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 […]

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 […]
