Computer security systems may one day get a boost from quantum physics, as a result of recent research into a “one-shot” memory unit, whose contents can be read only a single time. The research, by Yi-Kai Liu from the National Institute of Standards and Technology, is being presented this week at Princeton’s Innovations in Theoretical […]
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 […]
Building on related research that showed how two entangled black holes could be linked by a wormhole, an MIT physicist has shown that two entangled quarks could also give rise to a wormhole that connects the pair of elementary particles. The new work bolsters the relatively new idea that the laws of gravity holding together […]
Using ultrafast spectroscopy, scientists have observed what happens at the subatomic level during the very first stage of photosynthesis and uncovered a much more fundamental interaction than had previously been considered possible. The researchers, from the U.S. Department of Energy’s Argonne National Laboratory and the University of Notre Dame, have published their findings in the […]
Physicists say they have found an equation which shows that non-locality and uncertainty, the two defining properties of quantum physics, are quantitatively linked and that the “amount” of non-locality is determined by the uncertainty principle. The result is a breakthrough in our basic understanding of quantum mechanics and addresses the question of why quantum behavior […]
