Physicists Explain How Human Eyes Can Detect Quantum Effects
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.
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 ...
Don't call it vaporware: Scientists use cloud of atoms as optical memory device (w/ video)
(Phys.org) —Talk about storing data in the cloud. Scientists at the Joint Quantum Institute (JQI) of the National Institute of Standards and Technology (NIST) and the University of Maryland have taken this ...
Building quantum states with individual silicon atoms
(Phys.org) —By introducing individual silicon atom 'defects' using a scanning tunnelling microscope, scientists at the London Centre for Nanotechnology have coupled single atoms to form quantum states.
Testing Einstein's E=mc2 in outer space
(Phys.org)—University of Arizona physicist Andrei Lebed has stirred the physics community with an intriguing idea yet to be tested experimentally: The world's most iconic equation, Albert Einstein's E=mc2, may be cor ...
Disappearing light: Precision measurement of an atomic transition
(Phys.org)—Modern precision measurements are spectacular feats of engineering. An excellent example is determining the passage of time. Before John Harrison's marine chronometer in the mid 18th century, ...
