Latest Bell's theorem Stories
A team led by the Austrian physicist Anton Zeilinger has now carried out an experiment with photons, in which they have closed an important loophole.
Physicists have proposed an experiment that could force us to make a choice between extremes to describe the behavior of the Universe.
A fundamental characteristic of quantum physics is the fact that two or more particles can exhibit correlations stronger than classically allowed.
Physicists of the group of Prof. Anton Zeilinger at the Institute for Quantum Optics and Quantum Information (IQOQI), the University of Vienna, and the Vienna Center for Quantum Science and Technology (VCQ) have, for the first time, demonstrated in an experiment that the decision whether two particles were in an entangled or in a separable quantum state can be made even after these particles have been measured and may no longer exist.
Physicists have developed the first conclusive test to better understand high-energy particles correlations.
Researchers have uncovered a fundamental link between the two defining properties of quantum physics.
Researchers have devised a new kind of random number generator, for encrypted communications and other uses, that is cryptographically secure, inherently private and â€“ most importantly â€“ certified random by laws of physics.
Physicists at UC Santa Barbara have made an important advance in quantum mechanics using a superconducting electrical circuit.
In quantum mechanics, a vanguard of physics where science often merges into philosophy, much of our understanding is based on conjecture and probabilities, but a group of researchers in Japan has moved one of the fundamental paradoxes in quantum mechanics into the lab for experimentation and observed some of the 'spooky action of quantum mechanics' directly.
Researchers at the National Institute of Standards and Technology (NIST) and the Joint Quantum Institute (NIST/University of Maryland) have developed a new method for creating pairs of entangled photons, particles of light whose properties are interlinked in a very unusual way dictated by the rules of quantum physics. The researchers used the photons to test fundamental concepts in quantum theory.
