Quantum Entanglement Visible to theNaked EyeBy Laura Sanders, Science News09.28.095:41 PM
By linking the electrical currents of two superconductors large enough to be seen with thenaked eye, researchers have extended the domain of observable quantum effects. Billions offlowing electrons in the superconductors can collectively exhibit a weird quantum propertycalled entanglement, usually confined to the realm of tiny particles, scientists report in theSeptember 24 Nature.
“It’s an exciting piece of work,” comments physicist Steven Girvin of Yale University. “Peopleare interested in pushing the boundaries of quantum mechanics.”Entanglement is one of the strangest consequences of quantum mechanics. After interacting ina certain way, objects become mysteriously linked, or entangled, so that what happens to oneseems to affect the fate of the other. For the most part, researchers have only found signs of

entanglement between tiny particles, such as ions, atoms and photons.John Martinis and colleagues at the University of California, Santa Barbara looked forentanglement between two superconductors, each less than a millimeter across. Thesesuperconducting circuits, made of aluminum, were separated by a few millimeters on anelectronic chip. At low temperatures, electrons in the superconductors flow collectively,unfettered by resistance.Despite each superconductor’s relatively large size, the electrons within move together in anaturally coherent way. “There are very few moving parts, so to speak,” Girvin says, whichhelped the scientists spot evidence of entanglement. “It’s a general fact that the larger an objectis, the more classical it is in its behavior, and the more difficult it is to see quantum mechanicaleffects.”In the new study, researchers used a microwave pulse to attempt to entangle the electricalcurrents of the two superconductors. If the currents were quantummechanically linked, onecurrent would flow clockwise at the time of measurement (assigned a value of 0), while theother would flow counterclockwise when measured (assigned a value of 1), Martinis says. Onthe other hand, the currents’ directions would be completely independent of each other ifeveryday, classical physics were at work.After attempting to entangle the superconducting circuits, Martinis and his team measured thedirections of the currents 34.1 million times. When one current flowed clockwise (measured asa 0), the team found, the other flowed counterclockwise (measured as a 1) with very highprobability. So the two were linked in a way that only quantum mechanics could explain.“It has to be in this weird quantum state for you to get those particular probabilities that wemeasure,” Martinis says. “The percentages of those different things are not something that youcan classically predict.”Finding entanglement between superconductors is “a fairly important milestone,” commentsAnthony Leggett of the University of Illinois at UrbanaChampaign. The new study “does seemto be rather unambiguous evidence for entanglement.”Such entangled superconductors might be used as a component in a powerful quantumcomputer, Leggett says. “People are very interested in the possibility of building a quantumcomputer,” and these kinds of systems may be quite good for that, he says.Martinis says that the technology for building advanced electrical circuits may be used to buildquantum circuits, too. “The hope is that since we know how to put together integrated circuitsin complex ways, that maybe we can make very complex quantum circuits in the same way,” hesays.He cautions, though, that a good quantum computer is a long way off. Researchers still need tofind a way to make entangled superconducting circuits last longer. And a good quantumcomputer would need more than two circuits. Martinis says his group will try to entangle threeand four such circuits next.In addition to providing technological advances, the new results add to the debate over whereto draw the line between quantum mechanics and the everyday physics that governs largescalephenomena. Researchers want to know how far quantum weirdness can go.“It’s interesting to test quantum mechanics on a large scale,” Girvin says. “Do things lookclassical on large scales because there’s something wrong with quantum mechanics?Personally, I think that’s wrong, but one never knows.”Image: Erik LuceroSee Also:Science News stories on Wired Science“Sudden Death” Threatens Quantum ComputingLast Days of Big American Physics: One More Triumph, or Just Another Heartbreak?NextGen Atom Smashers: Smaller, Cheaper and Super PowerfulRelatedYou Might Like

As an Orthodox Christian priest, I view the advances in subatomic physicswith interest and delight.
Here we have evidence, at the fundamental level, of the unity of all thingswithin the creation. It's sort of like when charmed particles were discovered, and we saw,rigjhty in front of us, the interaction betweenthe creation and the Creator.
We have all heard the one about the physicists, after days of climbing,finally summiting the mountain only to see a group of theologians havinga picnic.
God bless you, and may you enjoy the climb as much as I'm enjoying watching it.
in Christ,

Entanglement is very interesting stuff. Einstein predicted it in the EPR paper (see wikipedia),but he published the paper to try to show how incomplete and unlikely quantum mechanicstheory was, not to justify/support it. He argued it was more logical that the 1/0 pairs werealready there all along for every property (what was called 'hidden variables') they justweren't measured yet. Entanglement says that when you measure a property of one part ofthe pair that it will be random (not hidden/predetermined), but whatever it's value, the otherpart of the pair (for just that one property!) must be the opposite if entangled (this happensfaster than light! but since you would have to know what the random value was of the first,no information can be transferred so no laws of physics are broken). And, all other propertieswould have zero correlation, purely random. It wasn't until Bell came up with a theorem(Bell's Theorem) that there was a statistical way to test for entanglement. Later experimentson entangled photons proved, using Bell's Theorem, that Einstein was wrong and QM wasreal. God *does* play dice, and spooky action at a distance (faster than light) *does* happen.Greene's book Fabric of the Cosmos has a great and easy to understand explanation ofentanglement.

@JohnStClair: Oh c'mon man! Give it up with the craziness! We all know there's no "left handChakra" and "right hand Chakra". We can all spot this sort of phony nonsense a mile away!To produce the sort of energetic effects you describe, one would have to open the rootChakra and allow the energy flow to elevate up, hold it in the heart Chakra until alignment isreached and then resume the flow sending wave-sparks out through the crown! Here's alittle diagram just in case you're a bit confused: http://upload.wikimedia.org/wi...

I remember an article in Scientific American about designing analog circuits using geneticalgorithms. One circuit that came out of the process was more efficient than the rest but hadsome kind of weird vestigial loop off to one side - it seemed to add nothing to the circuit,and in fact the circuit could work without it. But with it, it was more efficient. It makes mewonder: Could that have been the result of a macroscopic quantum effect?

Quantum entanglement can be seen in energy healing known as Matrix Energeticsdeveloped by Richard Bartlett. Information on the patient is obtained through the left handchakra which reads the patient's condition. A pulsed wave is sent out the right hand chakrawhich causes the energy field to oscillate. A wave is sent into the future and into the past.The healed state in the future is hit by the wave and sends out its own wave into the futureand into the past. All waves cancel except for the two waves between future and presentstates. The collapsed wave brings the healed state into the present where say a broken footis healed by the next day. What I find remarkable is that before you transmit a wave on anantenna, the advanced wave from the future arrives before you transmit the retarded wave.This of course keeps the energy in the universe balanced.

Quantum entanglement has been accessed in the experiments, irrelevant to quantummechanics, but the result is a speed difference of electricity with magnetism As it comes in: - Galilean relativity is correct. Einstein relativity is wrong.- The speed of light is not relevant to the observer.- The speed of light is related to the properties of ether. As the speed of sound is related tothe properties of air.- The speed of light is the speed of electricity. The speed of light is not relevant to the

magneto speed.- Speed of magnetic waves is related to the magnetic properties of ether. So it is muchgreater than the speed of light. As the speed of gravitational waves is much greater than thespeed of light. 10 ^ 24 times.- That is right, space (not spacetime) is made up of pieces, like light is made of photons. Forthe structure of these pieces, please contact us: [email protected]

Most of you people speaking about ether or Aether make up retarded crazy storiesabout science. light is an ElectroMagnetic wave; it is a combo of electric andmagnetic fields and I'm sorry they travel at the same rate. Nonsense; One day maybea valid Aether theory will pop up; But it seems to attact nutjobs whose think scienceis what they think instead of observations.

Most of you scientists are religious to the founders, and to the basicknowledge. Light is an electric current, without electron, in a magnetic media.entanglement experiment show different speed between light and magnetism.yes; A valid Aether theory poped up.

@ Badtim_1 Gosh, I don't know what more I can do for you. In my blog I gave you four majordiscoveries in physics. They are:1. The discovery of the circular co-gravitational k field similar to the magnetic field inelectromagnetism.2. The discovery of hyperspace.3. The discovery of instantaneous energy healing of viral, fungal and bacterial infectionsincluding broken bones and MS.

So given this experiment, what would happen if one of the circuits were placed on Mars afterinitial entanglement? Would we be able to communicate faster than the speed of light bymanipulating the earthbound circuit and having a robot on Mars interpret commands byobserving the direction of the current on the second circuit?

@JohnStClair But only if the incident left hand chakra pulse is perpendicular to the flux ofretarded co-dimensional quantum response wave. And only on every other Saturday (excepton leap years) between the hours of 3pm and 5pm. And not in AL, GA, or TN...their chakrawaves are too biblically inhibited.

As quantum communication circuits entangle does their power potential increaseexponentially, so that a minimum core entanglement will provide and produce prodigiousamounts of information.
Two circuits/cores .... potential power two sources squaredThree circuits/cores ....potential power three sources cubed

I always thought that the Heisenberg Uncertainty Principle was confined to quantummechanics. However it applies to any wave. I would modify the experiment by flooding thesuperconductor with low density hyperspace energy. This would pull electrons out ofdimension. Information lost to hyperspace is negative energy. Thus the device could beconverted into a negative energy generator. Mounted on a space station, the negativeenergy would cool the earth and eliminate global warming.

The energy healer has to disentangle from the healing, so the left hand is removed from theneck. It is necessary to disentangle the energy side "by tossing the left brain a bone." Thebone is a picture of a zany duck which the left brain is forced to process. This frees the rightbrain from the collapse of the quantum field. The healer can get into low light speed co-dimensions where space-time becomes wavy as the detection of gravitational wavesbecomes apparent.

The headline is in need of some editing -- you can see the *components* of the circuit, butyou can't actually see the entangled currents. Also, how high is the "very high" probability?Much higher than expected (e.g. 51% of the time) or close to 100%?

if someone wants to demonstrate meso or macroscopic scale entanglement, it would bebetter to have something more than a study that"does seem to be rather unambiguous evidence for entanglement".
