Making quantum encryption practical
One of the many promising applications of quantum mechanics in the information sciences is quantum key distribution (QKD), in which the counterintuitive behavior of quantum particles guarantees that no one can eavesdrop on ...
Physicists develop revolutionary low-power polariton laser
(Phys.org) —Lasers are an unseen backbone of modern society. They're integral to technologies ranging from high-speed Internet services to Blu-ray players.
Lab sets a new record for creating heralded photons
(Phys.org) —Entanglement, by general consensus of physicists, is the weirdest part of quantum science. To say that two particles, A and B, are entangled means that they are actually two parts of an inseparable ...
IceCube Neutrino Observatory reports first evidence for extraterrestrial high-energy neutrinos
(Phys.org) —A massive telescope in the Antarctic ice reports the detection of 28 extremely high-energy neutrinos that might have their origin in cosmic sources. Two of these reached energies greater than ...
Superfluids: Observation of 'second sound' in a quantum gas
Second sound is a quantum mechanical phenomenon, which has been observed only in superfluid helium. Physicists from the University of Innsbruck, Austria, in collaboration with colleagues from the University ...
Team uncovers fundamental property of astatine, rarest atom on Earth
An international team of scientists, including a University of York researcher, has carried out ground-breaking experiments to investigate the atomic structure of astatine (Z=85), the rarest naturally occurring ...
New principle may help explain why nature is quantum
Like small children, scientists are always asking the question 'why?'. One question they've yet to answer is why nature picked quantum physics, in all its weird glory, as a sensible way to behave. Researchers ...
