Toward an “unbreakable” message exchange
WÜRZBURG, Germany – Single particles of light produced and implemented into a quantum key distribution (QKD) link could pave the way for unbreakable communication networks. The single photons were produced by a collaboration of German scientists using two devices made...
Toward an ‘Unbreakable’ Message Exchange
WÜRZBURG, Germany, Aug. 6, 2012 — Single particles of light were produced and implemented into a quantum key distribution link, paving the way for unbreakable communication networks.
Physicists Confirm Born’s Rule
INNSBRUCK, Austria & WATERLOO, Ontario, Canada, July 22, 2010 — Using a single-photon source, Austrian and Canadian quantum physicists said they ruled out the existence of higher-order interferences experimentally and confirmed an axiom in quantum physics: Born’s rule.
Laser Device Produces Dark Pulses
GAITHERSBURG, Md., June 10, 2010 — Researchers have demonstrated a new type of pulsed laser that excels at not producing light. The new device generates sustained streams of "dark pulses" – repeated dips in light intensity – which is the opposite of the bright bursts in a...
Lasers Lengthen Qbit Memory
ANN ARBOR, Mich., June 24, 2009 – Physicists have found a way to drastically prolong the shelf life of quantum bits, the 0s and 1s of quantum computers. A quantum dot is a semiconductor nanostructure that is one candidate for creating quantum bits. The scientists, including the...
Polarized Raman Confocal Microscopy Maps Nanowires
Feb 1, 2006 — Scientists at the University of California, Berkeley, Lawrence Berkeley National Laboratory, also in California, and Université Bordeaux 1 in Talence, France, have reported that polarized Raman confocal microscopy may be used to collect information...
OPTICS, QUANTUM DOTS
Feb 1, 2005 — The 565-page resource Optics of Quantum Dots and Wires describes the status and potential of the technology. Chapters cover such areas as carrier relaxation in nanostructures, fabrication of stressor quantum dots, self-ordered quantum...
ASIP Lands Photonics R&D Grant
Aug 25, 2004 — SOMERSET, N.J., Aug. 25 -- ASIP, a Princeton University photonics spinoff company, has secured a $2.5 million contract from SenterNovem, part of the Dutch Ministry of Economic Affairs, to study advanced semiconductor nanostructures and photonic...
