Study identifies recipe for Goldilocks quantum phase transitions

University of Miami researchers have found that crossing a quantum phase transition at just-the-right speed generates the richest, most complex light-matter entanglement – a characteristic evident in our Universe. Such structure resembles “defects” in an otherwise smooth and empty space. The findings are published in Physical Review A, the American Physical Society’s main journal. “Our […]

Physicists map quantum to classical collapse




Extracting information from a system as it collapses from a quantum state to a classical state was never considered possible by the original founders of quantum theory, but Berkeley physicists have managed to extract information from a system continuously throughout its change of state, an achievement they say is like monitoring Schrodinger’s cat through the […]

Quasars at opposite ends of the Universe could close a loophole in quantum mechanics




Physicists have proposed an experiment that may close the last major loophole of Bell’s inequality – a 50-year-old theorem that, if violated by experiments, would mean that our Universe is based not on the laws of classical physics, but on the probabilities of quantum mechanics. In 1964, physicist John Bell took on this seeming disparity […]

The cloning of quantum information from the past may be Achilles’ heel of quantum cryptography




While the notion of physically travelling through time may still be the stuff of science fiction, a new research paper from Louisiana State University shows that it is theoretically possible to copy quantum data from the past. The new work has surprising ramifications for the field of quantum cryptography, which is widely touted as the […]
