"The new findings, being reported this week in the journal Science, are purely theoretical, but Lloyd says that laboratory experiments have already proven the feasibility of both the light sources and the detectors needed for such a quantum-based photodetection system, so he anticipates that within a year it should be possible to build a laboratory-scale system to demonstrate the new concept.
"It should be possible to have at least a proof-of-principle demonstration within six months to a year," Lloyd said.
For example, military applications could include improved night-vision systems, which send out beams of infrared light--invisible to the naked eye--to sweep across a scene, and then use an infrared detector to reconstruct an image from the light that is reflected back. A more efficient system, using the quantum-entanglement effect, would make it much more difficult for an adversary to detect the fact that such a system was being used, because there would be so much less infrared light needed to provide the illumination."

Discussing the paper 'Love-in-idleness' for the CR Greece with Milena Szafir and Ralf Flores. And here a list of shared references...
Andy warhol's experimental film
Andy Warhol's original Screen Tests were originally filmed from early 1964 - November 1966 (GM25). Factory visitors who had potential "star" quality would be seated in front of a tripod mounted camera, asked to be as still as possible, and told not to blink while the camera was running. These film portraits were some of the earliest examples of Warhol's Screen Test series. It is interesting to note that they were filmed in Edey's apartment prior to Warhol's move to the silver Factory where most, but not all, of the other Screen Tests were made. More than 500 Screen Tests were made. In addition to The 13 Most Beautiful Boys, some of the footage was incorporated into other compilation reels such as The 13 Most Beautiful Women (1964) and 50 Fantastics and 50 Personalities (1964). Malanga also used some reels in his multimedia poetry readings called Screen Test Poems in 1965. In 1966 Andy and Gerard also prepared a book together of Screen Test stills from 54 subjects (17 women and 37 men) and Gerard's poetry called Screen Tests/A Diary (NY: Kulchur Press, 1967).

Eye Tracking in Video Game Player Experience
Researchers at the Blekinge Institute of Technology conducted an eye tracking experiment on players’ experience with Half Life 2. A specially modified Half Life 2 game was built using the game’s software development kit to correspond with the players’ eye tracking gaze. In the experiment, players do not completely control the game through eye tracking. Instead, a keyboard controls each player’s movement and eye tracking is used to control the first person camera view. The researchers measured the players’ ability to navigate through the game environment using gaze as a steering method. To help contrast the differences, players were allowed to switch between gaze and mouse navigation.

We derive the optimal curve satisfied by the reduction factors, in the case of universal disentangling machine which uses only local operations. Impossibility of constructing a better disentangling machine, by using non-local operations, is discussed.

Disentangling Quantum States while Preserving All Local Properties

Electrical Engineering, UCLA, Los Angeles, California 90095-1594
Received 12 January 1999; published in the issue dated 16 August 1999
We consider here a disentanglement process which transforms a state ρ of two subsystems into an unentangled (i.e., separable) state, while not affecting the reduced density matrix of either subsystem. Recently, Terno [Phys. Rev. A 59, 3320 (1999)] showed that an arbitrary state cannot be disentangled, by a physically allowable process, into a tensor product of its reduced density matrices. In this Letter we show that there are sets of states which can be disentangled, but only into separable states other than the product of the reduced density matrices, and other sets of states which cannot be disentangled at all. Thus, we prove that a universal disentangling machine cannot exist.

hyper-entanglement
Controlling multiple qubits with hyper-entanglement
Controlling multiple qubits with hyper-entanglement
Controlling multiple qubits with hyper-entanglement
By Casey Johnston | Published about a year ago
Scientists are quickly putting the single-qubit system out of fashion with new setups that can simultaneously manipulate and read multiple qubits. An international collaboration recently completed an experiment involving the control of up to ten qubits at once, using hyper-entanglement and simple "cat states." While the system doesn't always read out perfectly, the approach could be further refined to produce better results.
Because qubit behavior is based in probability, it is difficult to exert a lot of control over a qubit. This problem gets a bit more significant as each additional qubit is added to the system, which has limited the number we can entangle at once. To hold down uncertainty and increase control as they add more qubits, scientists are now experimenting with hyper-entanglement, or entangling qubits on multiple levels at once. To put that another way, instead of entangling 10 different quantum objects, the authors entangled two separate properties of five items.
In this new experiment, scientists hyper-entangled sets of six, eight, and ten qubits in "cat states," or an equal superposition of two states (named after Schrodinger's cat, which occupied a superposition of the states "dead" or "alive"). The photons were entangled in two degrees of freedom: their polarization and their spatial modes. To get output from the photons once they were entangled, scientists used a special kind of interferometer that could gather information about one of the degrees of freedom without disturbing the other.
When the photons were measured, the photons produced the desired state around 60 percent of the time, with anything greater than 50% considered to be good enough to indicate that the system works at all. The eight-qubit system gave the best results, at 77.6 percent. The greatest limit of the system, according to the authors, was the photon detection efficiency, which will need to be significantly improved before implementation would be practical.
(Incidentally, the references to cat states start in the title—"Experimental demonstration of a hyper-entangled ten-qubit Schrödinger cat state"—and continue from there, with references to "ideal cat states" and "the hyper-entangled 2n-qubit cat state." "Cat" even appears as a term in some equations.

Wide Open
Midsummer Nights Dream Act IV Scene I - A wood - Titiania [i.e., Titania], queen of the fairies, Bottom, fairies attending & etc."
by Henry Fuseli, 1741-1825
... neither the reality of a single night nor even of a person's entire life can be equated with the full truth about his innermost being. And no dream, he responds is altogether a dream.( Schnitzler )
Wide Open or Around Quantum Entanglement, Dreams and Synchronicity//
Around December 23 2011 me and Milena Szafir, started talking via e-mail, bringing to discussion ideias that could converge in a paper that we can write together for the next Consciousness Refremed conference, that will be held in Greece - TECHNOETIC TELOS Art, Myth and Media
"Its theme from the conjunction of telos and tele, in the purposes and processes of art in the post-digital culture. At the center of these considerations is Mind, and the rich variability of consciousness and reality, to which technoetic systems and syncretic creativity aspire. Papers and projects are welcomed that address these issues, and which seek insights into the function of metaphor and myth in the emergent complexity of the post-biological era."
Here, some of the references we wandered and shared:

NATHANAEL TO LOTHAlR
"Oh! my dear, dear Lothair, what shall I say to make you feel, if only in an inadequate way, that that which happened to me a few days ago could thus really exercise such a hostile and disturbing influence upon my life?"
. . . . .
"When Nathanael awoke he felt as if he had been oppressed by a terrible nightmare; he opened his eyes and experienced an indescribable sensation of mental comfort, whilst a soft and most beautiful sensation of warmth pervaded his body. He lay on his own bed in his own room at home; Clara was bending over him, and at a little distance stood his mother and Lothair. "At last, at last, O my darling Nathanael; now we have you again; now you are cured of your grievous illness, now you are mine again."
can we start talking about synchronicity?
unus mundus...
One of Jung's favourite quotes on Synchronicity was from Through the Looking Glass (And What Alice Found There) by Lewis Carroll:
The rule is, jam to-morrow and jam yesterday--but never jam to-day.'
'It MUST come sometimes to "jam to-day,"' Alice objected.
'No, it can't,' said the Queen. 'It's jam every OTHER day: to-day isn't any OTHER day, you know.'
'I don't understand you,' said Alice. 'It's dreadfully confusing!'
'That's the effect of living backwards,' the Queen said kindly: 'it always makes one a little giddy at first--'
'Living backwards!' Alice repeated in great astonishment. 'I never heard of such a thing!'
--but there's one great advantage in it, that one's memory works both ways.'
'I'm sure MINE only works one way,' Alice remarked. 'I can't remember things before they happen.'
'It's a poor sort of memory that only works backwards,' the Queen remarked.

How to See Quantum Entanglement
Human eyes can detect the spooky phenomenon of quantum entanglement — but only sometimes, a new study on the physics preprint website arXiv.org claims. While eyes can help determine if two individual photons were recently entangled, they can’t tell if the brighter bunch of photons that actually hit the retina are in this bizarre quantum state.
“In general you think these quantum phenomena that involve only a few particles, they’re really far removed from us. That is actually not so true anymore,” said physicist Nicolas Brunner of the University of Bristol. “You could really go to an experiment by just having people look at these photons, and from there really actually see entanglement.”
In an earlier paper, Brunner and colleagues at the University of Geneva in Switzerland sketched out an experiment in which a human observer could replace a standard quantum detector. This isn’t as far-fetched as it sounds, they say, because the eye’s most important job is to be a sensitive photon detector...
Quantum Entanglement Visible to the Naked Eye
"By linking the electrical currents of two superconductors large enough to be seen with the naked eye, researchers have extended the domain of observable quantum effects. Billions of flowing electrons in the superconductors can collectively exhibit a weird quantum property called entanglement, usually confined to the realm of tiny particles, scientists report in the September 24 Nature."

Shakespeare’s Botanical References – Love In Idleness Flowers:
"It is evident that William Shakespeare was fluent in the folklore and history of the flora and fauna of his homeland. You can find references to different species of plants and their related superstitions and histories in all of his published works. Many Shakespearean scholars have devoted entire works to his botanical and folklore references. Here we will deal with only one species, Heartsease (Viola tricolor) otherwise known as the Love in Idleness Pansy. A common wild flower of the day, it was well-known to the Elizabethan herbalists."
from Shakespeare's A Midsummer Night's Dream: (wiki ref.)
Oberon calls for his court jester Robin Goodfellow to help him apply a magical juice from a flower called "love-in-idleness," which when applied to a person's eyelids while sleeping makes the victim fall in love with the first living thing seen upon awakening:
Yet mark'd I where the bolt of Cupid fell:
It fell upon a little western flower,—
Before milk-white, now purple with love's wound,—
And maidens call it love-in-idleness.
Fetch me that flower, the herb I showed thee once:
The juice of it on sleeping eyelids laid
Will make or man or woman madly dote
Upon the next live creature that it sees.
— Shakespeare's A Midsummer Night's Dream (Act 2, Scene 1)

Synchronicity
Synchronicity is the experience of two or more events that are apparently causally unrelated or unlikely to occur together by chance and that are observed to occur together in a meaningful manner. The concept of synchronicity was first described in this terminology by Carl Gustav Jung, a Swiss psychologist, in the 1920s.[1]
The concept does not question, or compete with, the notion of causality. Instead it maintains that, just as events may be grouped by cause, they may also be grouped by meaning. A grouping of events by meaning need not have an explanation in terms of cause and effect. For example, the words Jung and junk both contain three of the same letters, in the same order. Such a grouping is acausal, yet meaningful, and would have utility in an English dictionary or a telephone directory.
