Quantum sensor's advantages survive entanglement breakdown
The extraordinary promise of quantum information processing—solving problems that classical computers can't, perfectly secure communication—depends on a phenomenon called "entanglement," in which the physical states of ...
Physicists suggest theory versus observational differences in the sun could be due to dark matter
Distant quasar spectrum reveals no sign of changes in mass ratio of proton and electron over 12 billion years
Apparatus measures single electron's radiation to try to weigh a neutrino
University of Washington physicists are part of a team that made a step forward in their efforts to pin down the mass of a neutrino, an elusive subatomic particle that played a role in the formation of the universe.
Experiments show that the careful choice of witnesses makes it easier to detect entangled quantum states
Accurately probing the delicate relationship between linked, or 'entangled', photons—irrespective of the distance between them—is an important element of quantum cryptography, and perhaps even teleportation. Now, A*STAR ...
Multiphysics invisibility cloak manipulates both electric current and heat
Physicists study magnetism with the roles of position and momentum reversed
Quantum model helps solve mysteries of water
Water is one of the most common and extensively studied substances on earth. It is vital for all known forms of life but its unique behaviour has yet to be explained in terms of the properties of individual molecules.
From metal to insulator and back again
New work from Carnegie's Russell Hemley and Ivan Naumov hones in on the physics underlying the recently discovered fact that some metals stop being metallic under pressure. Their work is published in Physical Review Letters.
