Closing the last Bell-test loophole for photons
(Phys.org) —An international team of researchers has reached a milestone in experimental confirmation of a key tenet of quantum mechanics, using ultra-sensitive photon detectors devised by PML scientists.
Physics team entangles photons that never coexisted in time
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 ...
Physicists succeed in closing last local realistic loophole for systems of entangled photons
A team led by the Austrian physicist Anton Zeilinger has carried out an experiment with photons, in which they have closed an important loophole. The researchers have thus provided the most complete experimental ...
'Spooky action at a distance' aboard the ISS
(Phys.org) —Albert Einstein famously described quantum entanglement as "spooky action at distance"; however, up until now experiments that examine this peculiar aspect of physics have been limited to relatively ...
Quantum teleportation performed with light from a quantum dot embedded in an LED
Researchers discover a way to avoid decoherence in a quantum system
Metamaterials provide active control of 'slow light' devices
LANL researchers and collaborators have made the first demonstration of rapidly switching on and off "slow light" in specially designed metamaterials at room temperature. Metamaterials are assemblies of ...
Researchers explore quantum entanglement
Albert Einstein called quantum entanglement—two particles in different locations, even on other sides of the universe, influencing each other—"spooky action at a distance."
