(Â鶹ÒùÔº)—Like many mathematical puzzles, the grasshopper problem is simple to state but difficult to solve: A grasshopper lands at a random point on a lawn of area 1, then jumps once, a fixed distance, in a random direction. ...
Quantum secret communication realizes secure information transmission-based on quantum principles. At present, the most developed quantum secret communication schemes are-based on quantum key distribution. In these schemes, ...
The first quantum-safe video conference was held between President Chunli Bai of the Chinese Academy of Sciences in Beijing and President Anton Zeilinger of the Austria Academy of Sciences in Vienna as the first real-world ...
(Â鶹ÒùÔº)—Is entanglement really necessary for describing the physical world, or is it possible to have some post-quantum theory without entanglement?
A trio of scientists who defied Einstein by proving the nonlocal nature of quantum entanglement will be honoured with the John Stewart Bell Prize from the University of Toronto (U of T). The prize recognizes the most significant ...
(Â鶹ÒùÔº)—Â鶹ÒùÔºicists have reported some of the strongest evidence yet that that the quantum world does not obey local realism by demonstrating new evidence for the existence of quantum entanglement. By performing an essentially ...
Quantum entanglement, one of the most intriguing features of multi-particle quantum systems, has become a fundamental building block in both quantum information processing and quantum computation. If two particles are entangled, ...
Australian and German researchers have collaborated to develop a genetic algorithm to confirm the rejection of classical notions of causality.
(Â鶹ÒùÔº)—For the first time, physicists have experimentally demonstrated the violation of "bilocal causality"—a concept that is related to the more standard local causality, except that it accounts for the precise way ...
(Â鶹ÒùÔº)—Â鶹ÒùÔºicists have demonstrated Bell correlations in the largest physical system to date—an ensemble of half a million atoms at an ultracold temperature of 25 µK. The presence of Bell correlations indicates that ...
