Sex

The Consequences of Decision by Jacob Livengood

SEX

(for Henry Stapp
who once conjectured
that consciousness is our reward
for collapsing the wave function.)

Could sexual cravings explain the equations
Of Heisenberg, Schrödinger, Born and Dirac
Is it sex that bedazzles the great Milky Way?
Is it sex that explains why quarks interact?

Sex that's animalistic
Sex that's deeply dirty and raw
Sex that feeds on Quantum Reality
Sex that fucks with Natural Law.

The hottest mystery in physics is this:
Out of what conceivable gateway
Do fresh new realities spring?
O World, please lead me to quantum temptation
Could "how matter gets real" be a sexual thing?

Sex that's subtle, sex that's delicate
As a single photon of light
Sex that tentatively fingers the Darkness
And, finding it good, impregnates the Night.

Innocent and uninhibited
By the ignorance of today
Sex that's teasing us to discover
How this Universe wants to play.

Neville's Brain

Although Neville's brain was in a state of superposition, he was, when fully probed, a naive realist. Lynden Stone 2014
Lynden Elizabeth Stone is an Australian visual artist who explores the richness and ambiguity of existence using metaphors derived from quantum physics. I first met Lynden in the context of her Metaphase Typewriter Revival project where she reproduced with modern technology a nutty old experiment of mine put together at the dawn of the computer age that explored the conjecture that elemental quantum randomness might be used by spirits, both embodied and immaterial, to communicate in human language if a suitable computer interface were provided.

Lynden recently came to America as an artist in residence at Crane Galleries in Philadelphia where she exhibited the revived metaphase machine and other work concerning the ambiguity of existence. She just now completed her PhD at Griffith University in Queensland for a thesis entitled Doubting Conventional Reality: Visual Art and Quantum Mechanics in which she surveys contemporary visual artists who are using quantum-physics metaphors in the visual arts -- including her own work in this arena.

Part of Lynden's PhD thesis included a public exhibition of her work. She asked me to contribute some program notes for this show and promised me "an original art work" in exchange. A few days ago I received in the mail a pizza-box-sized package that contained Lynden's art work Neville's Brain.

In one simple image Lynden invokes several famous physicists beginning with the image of the Moon in the upper left corner. Lynden renders this moon in lenticular photography which was invented by British physicist David Brewster (who also invented the kaleidoscope). In the present context the moon image also suggests Einstein's famous quantum question to physicist Abraham Pais: "Do you really believe that the Moon does not exist when nobody looks?".

The black-and-white background of Lynden's piece consists of distorted Greek letters "psi" which is the symbol for the wavefunction in quantum theory. Neville's superposed brain is reminiscent of the "Wigner's Friend paradox" in quantum mechanics as well as John von Neumann's conjecture that when humans observe a superposed quantum system, their brain states should also turn into superpositions.

The fact that Neville is a naive realist despite his superposed brain summarizes the basic quantum conundrum of why the world always appears "classical" despite the fact that physicists can prove that the world is entirely "quantum". Today, the real mystery is not quantum mechanics; the real mystery is why the world appears to humans to be stubbornly classical.

We house-broke quantum reality
Taught Schrödinger's Cat to purr
Now daily life's as uncanny
As atoms ever were.

At the bottom right is the fuzzy sketch of an animal which might possible represent the famously ambiguous Schrödinger Cat. Except that Lynden's animal looks just like a dog.

Thank you, Lynden Stone, for this rich and original work. I will treasure it like a quantum Picasso.

The Heart of Aikido

LInda Holiday Sensei, Aikido of Santa Cruz
For a long time I have been curious about the contention that some sort of invisible energy flows between people, an energy my dancer wife Betsy referred to as "just energy, Nick" and that many Oriental thinkers have called "prana", "chi" or "ki". So I decided a long while back to see if I could experience this mysterious psychic fluid first hand and started by signing up for aikido classes at North Bay Aikido in Santa Cruz. I purchased a "gi" (aikido uniform) and three times a week I was practicing throwing and being thrown to the mat by lots of different people of assorted sizes, abilities and genders. I liked aikido a lot, both as a sport, as a novel way of interacting with strangers and as a philosophy of life.

I practiced aikido for several months until a physical condition (not related to the dojo) forced me to give up the sport and I never returned. Although I failed in my attempt to "see ki", I gained a lot of confidence in the powers of my own body plus I became acutely aware of the bodies of other people -- everyone I met I perceived as a potential aikido partner. Throwing and being thrown hundreds of times by strangers had paradoxically made me more comfortable with people and more eager to engage with them.

AIKIDO = HARMONY KI WAY
The character "ki" is derived from a picture of rice cooking in a pot.

A friend of mine is writing a book for North Atlantic Books and invited me to go with him to visit the NAB offices in Berkeley. While skimming their archives, I discovered that NAB had just published a new book Journey to the Heart of Aikido by my former aikido teacher, Linda Holiday. So I returned to my old dojo (now in a big, brand-new location) and bought a copy from Linda herself.

Journey to the Heart of Aikido
The first thing I realized when studying aikido was that "no amount of reading is going to do you any good here, Nick. Aikido is something that you can't learn from books." But once you have practiced a bit of aikido, Linda's book can help deepen your appreciation of this marvelous sport.

In her book, Linda describes two hearts. One is a physical place and the other is an invisible entity.

The physical "heart of aikido" is the Kumano Juku Dojo in Shingu, Japan, where the founder of aikido, Morihei Ueshiba (known simply as O-Sensei = Great Teacher) began sharing this new martial art with his students. The city of Shingu is located in Pacific coastal mountains forested by Japanese sugi trees that resemble American redwoods. So much does the landscape of Shingu resemble Santa Cruz that now, largely through the efforts of aikido students, the two towns have officially become sister cities.

Given that Kumano Juku Dojo is the physical "heart of aikido", Linda describes three separate journeys to this aikido heartland. The first is the story of O-Sensei's life as a teacher of martial arts to an elite military and political class and his decision to teach a new kind of combat based on "harmony" and the notion of "no opponent". O-Sensei journeyed to Shingu to set up the Kumano Juku Dojo in a small rural town noted for its shrines, a obscure location in the Japanese countryside close to where he was born.

The second journey to the heartland is the story of Linda's own pilgrimage to Shingu to study aikido as one of the few Westerners and even fewer women members of the Kumano Dojo. O-Sensei had died a few years before Linda's arrival but she and her Western associates were privileged to practice aikido with many experts who had studied directly with the Master himself. This second story tells how Linda fell in love with aikido, and eventually with the Japanese culture and language out of which it arose.

The third journey to the aikido heartland is that of Motomichi Anno, a worker in a Japanese paper factory, who traveled to Shingu shortly after WW II to study with the mysterious martial artist in the woods and eventually become one of the directors of his dojo. Anno Sensei was one of Linda's favorite teachers. When she returned to America she invited him to come to her own dojo in Santa Cruz to teach and speak about aikido while Linda translated his talks from Japanese into English.

The journey to the "spiritual heart of aikido" consists of Linda's own impressions of her journey and her translations of the exchanges between American students and her venerable Japanese teacher about the language and philosophy that surrounds the practice of this wordless art. In these discourses, Anno Sensei gives his own impression of aikido and attempts to clarify exactly what's meant by such terms as "heart", "spirit" and yes (my old favorite) "ki", as he understands these terms as transmitted to him directly by the founder O-Sensei.

This book (richly illustrated with pictures of O-Sensei, aikido practices and the Kumano countryside) will be of interest to anyone curious about the history of aikido. Linda is a good story teller. But those who will derive the greatest value from this book will be aikido students of any rank. Reading Journey to the Heart of Aikido will deepen in many ways our appreciation of why we are taking and giving all these falls only to keep coming back for more.

Linda's book includes a glossary of Japanese words common in the aikido community and an illustrated warm-up exercise straight from the Kumano Juku Dojo. "This exercise," says Linda, "which combines meditation, breathing, visualization, and movement, is a purification practice that O-Sensei often did at the beginning of class. Its purpose is to develop a state of unity with the spirit of the universe."

The best books are written by those who love their subject. For this scholarly, inspiring and loving glimpse into the many hearts of this fascinating martial art, domo arigato. Thank you very much, Linda Holiday Sensei.

WORK IN PROGRESS

Come for the lunch
And stay for the tantra:
Taking new chances
In life-and-death dances
With creatures
That you barely know.

Come for the truth
And stay for the magic:
Share drugs and kisses,
Hesitations, near misses
With seekers
You meet in the flow.

Come for the sex
Stay for quantum reality:
Learn tricks of attention
In half-sensed dimensions
From teachers
Whose lessons explode.

Nick Emits Antimatter

Nick emits: 1 positron every 12 seconds
Fausto Marcon recently drew my attention to a blog post  by "tertiary source" entitled What's the Antimatter Content of a Banana? .

I guessed "Zero" but I was wrong.

I know that bananas are radioactive because they contain a lot of Potassium. And some of that Potassium exists as Potassium-40 (K-40), a long-lived radio-isotope left over from the creation of the Earth. But I had imagined, that K-40, like most naturally occurring radio-active substances, emitted beta and gamma rays which are just high-speed electrons and high-frequency light. In other words, ordinary matter -- just a bit more highly excited than the matter in your lipstick and in your coffee cup.

And that's for the most part correct.

But if you look up Potassium-40 in Wikipedia (which can be trusted on subjects as uncontroversial as the properties of atoms), you will find that this isotope possesses three separate decay modes. And that one of these decay modes involves the emission of a positron (or anti-electron) which is a fundamental particle with the same mass as the electron but with opposite charge. The positron is the simplest example of "antimatter" with the property that when an electron (matter) meets up with a positron (antimatter) both particles disappear in a flash of light (gamma rays) -- a process aptly named matter-antimatter annihilation. The positron was the first anti-particle discovered (by Carl Andersen in 1932) but every known particle has an antimatter partner, all of whom (I believe) have now been detected.

So along with a bunch of ordinary radioactivity, a banana emits antimatter as well, at a rate "tertiary source" estimates to be about 1 positron every 75 minutes -- or about 20 positrons per day.

But my body is filled with Potassium too. And I weigh a lot more than a banana. How much antimatter does Nick emit per day?

Let's face it. Everybody emits radiation whether they are aware of it or not. The main bodily radioisotopes are Potassium-40 and Carbon-14. If you are of average height and build, your radioactive Potassium will produce about 5000 decays per second while your radioactive Carbon produces 3000 decays per second. Much of this radioactivity is absorbed by the body but some escapes and can be detected by a sensitive radiation detector.

Though no fault of your own your body is radioactive.

During the past 60 seconds, the Potassium and Carbon inside your body have produced nearly 1/2 a million radioactive decays. But only a small fraction of these half-million decays are made of antimatter. The body's positron emission rate is about 5 per minute.

A banana takes about 75 minutes to create a single positron, but Nick emits antimatter every 12 seconds.

Nick emits antimatter every 12 seconds.

And so do you.

Detour John

Quantum Physicist or Outlaw Biker?
Several years ago my friend Fred McPherson and I carried out a monthly Dump Run Ritual. We'd get up early, put on our old clothes, load up Fred's pickup truck with trash, brush and garbage from both our homes, then drive to the outdoor dump in Ben Lomond where we would empty the truck and hung out with other dumpers and scavengers. Afterwards we would return to Boulder Creek to eat lunch and drink beer at Adelita's Mexican restaurant -- alas no longer in business -- which served the best chile rellenos in Santa Cruz county.

As we pulled into Adelito's parking lot we noticed a cluster of newly arrived bikers who belonged to one of the local outlaw motorcycle clubs and who seemed to share our taste in Mexican food. (Such clubs were plentiful in Boulder Creek in the old days, but today a guy on a Harley in Boulder Creek is more likely to be a manager at Apple than a Hell's Angel from Oakland.) These guys in the lot were the real thing, not Angels I think but some local gang like Ghost Riders from Lompico.

The bikers watched our truck pull up. And then the biggest, hairiest and most decorated of these Black Knights of the Road slowly walked over to my side of the car. I had no idea what to expect as this Levi-jacketed berserker stared me right in the eye and reached for my door handle.

Suddenly the big biker stopped and laughed. "Excuse me," he said. "I thought you were somebody I knew." Then he turned and sauntered back towards his pack. "Hey, come back here," I shouted to his retreating form, no longer puzzled about his purpose. When he turned in our direction, I asked him what was the name of the guy that I reminded him of?

"Detour John," said the biker and rejoined his crew.

I really like the name.

And it amused me immensely that Nick Herbert could be mistaken in Boulder Creek for an outlaw biker. But most of all, I was pleased that somewhere in this marvelous world there exists an outlaw biker whose name is Detour John and who looks like a quantum physicist from Stanford.

Speaking of quantum physics, Nick just co-authored a physics paper on a special class of faster-than-light signaling schemes. John Cramer (University of Washington, Seattle) came up with an original idea for an FTL signaling scheme that involves polarization-entangled photons interacting with a novel beam-spitting device -- a device which I dubbed the "Cramer wedge". At first, it looked as though this wedge could robustly accomplish its intended job, and that FTL signaling was indeed within our grasp. However soon John and I were able to show to our satisfaction, that when the operation of this wedge is correctly calculated, all signaling effects vanish. Our paper entitled "An Inquiry into the Possibility of Nonlocal Quantum Communication" is scheduled to be published in Foundations of Physics journal. A preprint of this work is available today on the ArXiv.

I was honored to be asked by John Cramer to take time out of my busy life to collaborate with him on this paper. I was glad for the chance to work with a famous physicist on a new FTL scheme that I had never before encountered.

Thanks for the engaging detour, John.

ALLAHPHONE

Suzi's hooked on meditation
Brian speaks to God on grass
Sufi Sam's a Whirling Dervish
And Brenda levitates at Mass.

Nature broadcasts night and morning
From every atom, leaf and bone
A trillion voices fill the Cosmos
But most are deaf to allahphone.

Go some place where humans aren't
Take an animal along
Allow yourself to deeply listen
Can you hear Dame Nature's song?

Nature broadcasts noon till midnight
From every rivulet, star and stone
A roaring wisdom fills the Cosmos
But most are deaf to allahphone.

Burning Man 2014

Burning Man 2014 -- the Playa after the rain
The Burning Man Festival, held every year at Black Rock desert near Reno, Nevada, is the closest thing in our modern God-is-Dead Era to a religious pilgrimage to a sacred site. Burning Man is reminiscent of Chaucer's Canterbury Tales in which Geoffrey Chaucer describes the adventures of a group of pious English pilgrims journeying to the shrine of St Thomas Becket at Canterbury cathedral near the end of the 14th Century.

Whan that Aprill, with his shoures soote
The droghte of March hath perced to the roote
And bathed every veyne in swich licour,
Of which vertu engendred is the flour...

And smale foweles maken melodye,
That slepen al the nyght with open eye
(So priketh hem Nature in hir corages)
Thanne longen folk to goon on pilgrimage.

In modern English:

When in April the sweet showers fall
That pierce March's drought into the root and all
And bathed every vein in sweet liquor with power
To generate therein and sire the flower...
And many little birds make melody
That sleep through all the night with open eye
(So Nature pricks them on to ramp and rage)
Then folk do long to go on pilgrimage.
"Then longen folk to go on pilgrimage". Not in April as in Chaucer's Tale. But in early September, just before the autumnal equinox, tens of thousands of people drive out to the middle of an empty desert to create their own temporary Canterburys, Stonehenges and Ka'abas on the sands of the Black Rock Playa. Burning Man still awaits its description at the hand of a Chaucer-class bard. But in lieu of that yet-to-be-famous Black Rock poet, my friend and neighbor, Bruce Damer, PhD, traveled to Burning Man this year to give a few talks and to take lots of photos which he has been sharing with his friends.

Here's Burning Man 2014 through Bruce's eyes. Thank you, dear Doctor Damer, Our Man in the Playa, for recording some fragment of this modern-day pilgrimage for the enjoyment of us stay-at-homes.

May the spirit
of Blessed Sasha Shulgin
be with you
as we mine new magic
out of the old mystery.


Some kinda impromptu temple in the desert?

Quantum Vampire Effect

Bela Lugosi as Dracula
Quantum mechanics is full of subtle and unusual processes that challenge our common-sense understanding of the world, for instance simultaneous particle/wave behavior, quantum non-locality, quantum entanglement and instant quantum teleportation. Now, thanks to four Russian researchers in Moscow and Calgary, Canada, a new example of quantum weirdness has been added to the list, the peculiar phenomenon called Quantum Vampire Effect (QVE).

Ilya Fedorov, Alex Ulanov, Yury Kurochkin and Alex Lvovsky announced the discovery of the Quantum Vampire Effect in a recent ArXiv post. Here I will attempt a brief description of the four Russians' discovery.

Quantum Vampire Effect: Removing a photon from part of a state removes the photon from the entire state.
The picture above illustrates an INTERFEROMETER, one of the physicist's most sensitive measuring devices. It works like this. A quantum state ψ at the left is split into two parts by beam splitter BS1 and then later recombined at beam splitter BS2. If the two paths suffer no change, the state ψ re-emerges intact. However if one of the two paths is perturbed by even the most minuscule change, reconstruction fails and some of the state ψ will end up in detector A.

Possible changes that might hinder the perfect reconstruction of ψ include changes in the density of the air, vibrations of the mirrors caused by a car passing outside or by people talking in the room. The INTERFEROMETER is a very very sensitive device.

So now we take this change-sensitive INTERFEROMETER and remove one photon from one of its paths by means of a weakly-transmitting mirror and a single-photon detector (see above). What do you think will happen? The answer to this question is the basis of the Quantum Vampire Effect.

What happens if we remove one photon from one of the beams is NOTHING. Well not exactly nothing, but almost nothing. The original state is preserved at the final detector; sensitive-change-detector A does not click. But the final state is missing one photon.

The final state is missing one photon. This means that taking ONE PHOTON from the PARTIAL STATE (one of the two beams into which the original state was split) is entirely equivalent to taking ONE PHOTON from the ENTIRE STATE. As far as the final result is concerned, the photon-eating device (weakly-transmitting mirror and detector) in partial beam φ1 could just as well have been placed at the beginning of the experiment where it would grab a photon from the whole beam instead of just a part.

In physics slang this photon-grabbing device is the material realization of the "photon annihilation operator" (symbolized by lower case a) which removes one photon from the associated quantum state. If operator a is applied to partial beam φ1 , this operation is written a(φ1). If the full state ψ has one photon removed, this photon removal operation is written a(ψ). The Quantum Vampire Effect amounts to the discovery that under very general conditions:
 

a (φ1) = a (ψ). 

That is, taking a photon from part of the state is exactly equivalent to taking a photon from ALL OF THE STATE.

So what?

Here's what.

If ordinary light absorption worked this way, objects would not cast shadows (hence the Dracula-inspired name). Instead the light as a whole would be dimmed.

The Quantum Vampire Effect does not cast a shadow but reduces the intensity of the light as a whole.
Ordinary Optical Absorption is much more complicated than the simple removal of one photon at a time by physical application of the annihilation operator "a". The realization of "a" is a DIP & CLICK operation which rarely happens in real life but is easy to do in an optics lab. What you do is DIP a mirror into the beam. And if you happen to catch a photon, your detector CLICKS. The Quantum Vampire Effect illustrated above can only be demonstrated if you throw away all ordinary absorptions and just keep the few chance events associated with DIPS & CLICKS.

But however artificial the Vampire Effect might seem, it has enormous philosophical import because it is a concrete example of an action on the part being equivalent TO THE SAME ACTION acting on the whole. One more little puzzle piece in the Great Quantum Mystery.

And perhaps the key to a brand-new super technology. If an action on a part can instantly affect the whole, can one perhaps use the Quantum Vampire Effect to send signals faster-than-light (FTL)?

Since I have been devising impromptu FTL signaling devices for most of my physics career, it was not difficult to see how to exploit the Quantum Vampire Effect to achieve ultra-fast telegraphy.

The trick is this: to start with a quantum state that possesses very few photons, so that the hyper-holistic DIP & CLICK operation results in an enormous change. For this purpose, the best input state one could imagine would be a 2-photon state. Then the DIP & CLICK operation would maximally switch the state (non-locally?) from a state consisting of two photons (symbolized |2>) to a state consisting of just one photon (symbolized |1>).

Accordingly, my new FTL design consists of a 2-photon Diagonally-polarized (D) input state which is split by a polarized beam splitter (PBS) into a Vertically-polarized (V) beam sent to ALICE and a Horizontally-polarized (H) beam sent to BOB.

For starts the initial D beam possesses two photons, which in each pulse are shared between ALICE and BOB. If ALICE detects two photons, BOB detects none. If ALICE detects one photon, BOB gets one too. And so on.

But now ALICE introduces a DIP & CLICK machine into her beam which locally removes one photon from her beam. But according to the Quantum Vampire Effect, Alice's act is NOT ONLY LOCAL BUT GLOBAL. Suddenly instead of sharing a two-photon D state, both ALICE and BOB are sharing a one-photon D state.

And these two kinds of state are easily distinguishable -- mainly by the utter lack of any two-photon counting events.

Is this it? Has the fair Muse of Physics finally delivered Nick his long-sought FTL signaling scheme? Please read on.
VLAD: a proposed FTL signaling scheme based on Quantum Vampire Effect


I decided to call it VLAD (for Vampire-Licit Ansible Device) -- "Ansible" being a famous fictitious FTL signaling device invented by sci-fi writer Ursula Le Guin.

And sure enough it works. The above illustration shows the VLAD scheme, including ALICE'S use of a partially-reflecting mirror to DIP & CLICK single photons out of her beam and record every such events with her "a Detector". ("a", you will recall, stands for the quantum photon annihilation operator).

For the VLAD setup, the Quantum Vampire Effect works as advertised: when nothing is done, the input is a two-photon state. But whenever ALICE snatches a photon from her local beam, the ENTIRE SYSTEM acts as though the input was just one photon all along.

The two equations accompanying the drawing represent the quantum wavefunctions for these two cases. 1. When there are two photons in the starting state, ψ(1) describes the situation; 2. When there is only one photon in the starting state, ψ(2) is the correct description.

VLAD "works" in the sense that BOB could easily distinguish which of these two wavefunctions describes the situation by looking at the pattern of photon counts at his detector. VLAD "works" in the sense that ALICE can select, by deploying her DIP & CLICK device or not, whether the wavefunction shall consist of two photons (ψ(1)) or of only one photon (ψ(2)).

But, alas, VLAD finally fails to work after all, because the output of ALICE'S DIP & CLICK occurs at random. Only if Alice sends BOB a signal (at light speed or slower) whenever her "a detector" clicks, can BOB know for sure that that he is looking at a one-photon state. Absent news of ALICE'S "a detector" click, BOB sees no change whatsoever in his pattern of photon clicks. Even through ALICE'S action has randomly embedded a one-photon pattern in the full photon stream, without a decoding signal from ALICE, BOB cannot extract these special events from the original two-photon situation. So says the mathematics. Once again clever Nature has prevented us from using Her marvelous quantum entanglement to send signals faster than light.

Goodbye to VLAD as an FTL signaling device. Farewell, VLAD. Da svedanya.

And the four Russians conclude their QVE paper thus: "We expect the quantum vampire effect to find applications in quantum information technology...The ability to "steal" a photon without casting a shadow may prove useful for eavesdropping in quantum key distributions as well as developing quantum cloaking devices. We also believe the effect to be of fundamental interest, as quantum action at a distance that is not associated with a local state collapse has not yet been studied."

I wish to thank Doctor Alex Lvovsky for patiently clarifying for me many subtle features of the Quantum Vampire Effect. Without his help this post would have been impossible.
