All-optical quantum computation, step 1: A controlled-NOT photonic gate
Quantum algorithm breakthrough
An international research group led by scientists from the University of Bristol, UK, and the University of Queensland, Australia, has demonstrated a quantum algorithm that performs a true calculation for the first time. ...
First-ever calculation performed on optical quantum computer chip
(PhysOrg.com) -- A primitive quantum computer that uses single particles of light (photons) whizzing through a silicon chip has performed its first mathematical calculation. This is the first time a calculation ...
Researchers create on-chip interference between pairs of photon sources
Distant artificial atoms cooperate by sharing light, physicists show
An international team of scientists has shown for the first time that atoms can work collectively rather than independently of each other to share light.
Quantum dot commands light: A solid state ultrafast logic gate on a photon
(Phys.org) —If you could peek at the inner workings of a computer processor you would see billions of transistors switching back and forth between two states. In optical communications, information from ...
Physicists build highly efficient 'no-waste' laser
A team of University of California, San Diego researchers has built the smallest room-temperature nanolaser to date, as well as an even more startling device: a highly efficient, "thresholdless" laser that ...
Teleported by electronic circuit: Physicists 'beam' information
ETH-researchers cannot "beam" objects or humans of flesh and blood through space yet, a feat sometimes alluded to in science fiction movies. They managed, however, to teleport information from A to B – for the first time ...
Advancing graphene for post-silicon computer logic: Researchers pioneer new approach for graphene logic circuits
A team of researchers from the University of California, Riverside's Bourns College of Engineering have solved a problem that previously presented a serious hurdle for the use of graphene in electronic devices.
Electronics play by a new set of rules at the molecular scale
(Phys.org)—In a paper published in Nature Nanontechnology on September 2, 2012, scientists from the DOE's Brookhaven National Laboratory and Columbia University's departments of Chemistry and of Applie ...
