Three scientists jointly won this year's Nobel Prize in physics on Tuesday for their work on quantum information science that has significant applications, for example in the field of encryption.
Alain Aspect, John F. Clauser and Anton Zeilinger were cited by the Royal Swedish Academy of Sciences for discovering the way that particles known as photons can be linked, or "entangled," with each other even when they are separated by large distances.
"Quantum information science is a vibrant and rapidly developing field," said Eva Olsson, a member of the Nobel committee. "It has broad and potential implications in areas such as secure information transfer, quantum computing and sensing technology."
"Its origin can be traced to that of quantum mechanics," she said. "Its predictions have opened doors to another world, and it has also shaken the very foundations of how we interpret measurements."
Three white men. I didn’t think that sort of thing was allowed these days. Has the Nobel committee received threats?
Working independently, the three laureates did key experiments that established the quantum property of entanglement. This is a curious effect whereby two or more particles display much stronger correlations than are possible in classical physics. Entanglement plays an important role in quantum computers, which in principle could outperform conventional computers at some tasks.
Bell’s inequality
All three of the experiments measured violations of Bell’s inequality, which places a limit on the correlations that can be observed in a classical system. Such violations are an important prediction of quantum theory.
The first experiment was done in 1972 at the University of California at Berkeley by Clauser, who measured the correlations between the polarizations of pairs of photons that were created in an atomic transition. He showed that Bell’s inequality was violated – which meant that the photon pairs were entangled.
However, there were several shortcomings or “loopholes” in this experiment, making it inconclusive. It is possible, for example, that the photons detected were not a fair sample of all photons emitted by the source – which is the detection loophole. It is also possible that some aspects of the experiment that are thought to be independent were somehow causally connected – which is the locality loophole.
Ten years later, in 1982, Aspect and colleagues at the Université Paris-Sud in Orsay, France, improved on Clauser’s experiment by using a two-channel detection scheme. This avoided making assumptions about the photons that were detected. They also varied the orientation of the polarizing filters during their measurements. Again, they found that Bell’s inequality was violated.
Third loophole
The locality loophole was closed in 1998 by Zeilinger and colleagues at the University of Innsbruck in Austria. They used two fully independent quantum random-number generators to set the directions of the photon measurements. As a result, the direction along which the polarization of each photon was measured was decided at the last instant, such that no signal travelling slower than the speed of light would be able to transfer information to the other side before that photon was registered.
As well as confirming a fundamental prediction of quantum mechanics, the three experiments laid the groundwork for the development of modern quantum technologies.

Long, long overdue for Alain Aspect.
Especially the one on the right...
From what I read, the ChiComs are trying to use quantum entanglement for stealth aircraft detection and communications security.
Not one of them has ever eaten bat soup.
They both won and didn’t win the Nobel Prize for Quantum Physics.
Soon there’ll be a Woke-bul Prize given to the Physicist who revealed that there was a massive particle/anti-particle war shortly after the big bang in which anti-matter was destroyed in a matter-civil war. We now have anti-matter phobia and must pay reparations to the anti-electron and its relatives.
Zeilinger has gone on from basic research to pioneer quantum encryption.
I did pretty well in high school algebra. If only I had stuck with it......
You mean Obama didn’t get it again for oh I dunno, owning a house on Martha’s Vinyard?

Spooky action at a distance.
Entangled quantum states hold the potential for new ways of storing, transferring and processing information.
Interesting things happen if the particles in an entangled pair travel in opposite directions and one of them then meets a third particle in such a manner that they become entangled. They then enter a new shared state. The third particle loses its identity, but its original properties have now been transferred to the solo particle from the original pair. This way of transferring an unknown quantum state from one particle to another is called quantum teleportation.
Great timing, what with Yom Kippur being "a day like Purim":

Half-Shekel -- Metaphor for Entanglement
A limitation of the model is that each recipient must already know what's on the other side, but isn't that the 'whole' idea.
Exo 30
11. And the Lord spoke to Moses, saying:
12. When you take the census of the people of Israel according to their number, then shall they give every man a ransom for his soul to the Lord, when you count them; that there should be no plague among them, when you count them:
13. This they shall give, every one who passes among those who are counted, half a shekel according to the shekel of the sanctuary; a shekel is twenty gerahs; a half shekel shall be the offering of the Lord:
14. Every one who passes among those who are counted, from twenty years old and above, shall give an offering to the Lord:
15. The rich shall not give more, and the poor shall not give less than half a shekel, when they give an offering to the Lord, to make an atonement for your souls:
16. And you shall take the atonement money of the people of Israel, and shall appoint it for the service of the Tent of Meeting; that it may be a memorial to the people of Israel before the Lord, to make an atonement for your souls:
17. And the Lord spoke to Moses, saying:
18. You shall also make a basin of bronze, and its pedestal also of bronze, to wash with; and you shall put it between the Tent of Meeting and the altar, and you shall put water in it:

The lone anagram "entanglement" word is interesting for a number of reasons. Within the manuscript letters is the half-uncial style.
Because an inch is defined as exactly 25.4 mm, 1/2 in. is 12.7 mm, and 50 in = 127 cm. (cognate meaning: Esther 1:1)
A modern half shekel = 50 agorot, and

This year he gets the peace prize for saying how he welcomes immigrants into his town and then providing an example of how government can be efficient by processing them for resettlement within 48 hours. Whatta guy!
