(Phys.org) —The way that thoughts and memories arise from the physical material in our brains is one of the most complex questions in modern science. One important question in this area is how individual thoughts and memories ...
(Phys.org)—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 ...
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, ...

(PhysOrg.com) -- By greatly amplifying one photon from an entangled photon pair, physicists have theoretically shown that human eyes can be used as detectors to observe quantum effects. Usually, detecting quantum phenomena ...
(PhysOrg.com) -- The latest test in quantum mechanics provides even stronger support than before for the view that nature violates local realism and is thus in contradiction with a classical worldview. By performing an experiment ...
The efficient generation of entanglement between remote quantum nodes is a crucial step in securing quantum communications. In past research, entanglement has often been achieved using a number of different probabilistic ...
(PhysOrg.com) -- An international team of physicists, including a scientist based at The University of Queensland, has recently closed an additional 'loophole' in a test explaining one of science's strangest phenomena -- ...
