Photon 'afterglow' could transmit information without transmitting energy
Traveling without moving: Quantum communication scheme transfers quantum states without transmitting physical particles
How well can information be stored from the beginning to the end of time?
Scientists achieve critical steps to building first practical quantum computer
IBM scientists today unveiled two critical advances towards the realization of a practical quantum computer. For the first time, they showed the ability to detect and measure both kinds of quantum errors ...
Electrical control of quantum bits in silicon paves the way to large quantum computers
A UNSW-led research team has encoded quantum information in silicon using simple electrical pulses for the first time, bringing the construction of affordable large-scale quantum computers one step closer ...
Black holes don't erase information, scientists say
The "information loss paradox" in black holes—a problem that has plagued physics for nearly 40 years—may not exist.
Quantum sensor's advantages survive entanglement breakdown
The extraordinary promise of quantum information processing—solving problems that classical computers can't, perfectly secure communication—depends on a phenomenon called "entanglement," in which the ...
Forbidden quantum leaps possible with high-resolution spectroscopy
A new twist on an old tool lets scientists use light to study and control matter with 1,000 times better resolution and precision than previously possible.
Correlations of quantum particles help in distinguishing physical processes
Communication security and metrology could be enhanced through a study of the role of quantum correlations in the distinguishability of physical processes, by researchers at the Universities of Strathclyde ...
Nanoscale mirrored cavities amplify, connect quantum memories
The idea of computing systems based on controlling atomic spins just got a boost from new research performed at the Massachusetts Institute of Technology (MIT) and the U.S. Department of Energy's (DOE) Brookhaven ...
'Single-photon emission enhancement' seen as step toward quantum technologies
(Phys.org)—Researchers have demonstrated a new way to enhance the emission of single photons by using "hyperbolic metamaterials," a step toward creating devices in work aimed at developing quantum computers ...
Amazon drone patent has tracking, talking details
Facebook not an information bubble, researchers conclude
Social media networks like Facebook are not putting users in an ideological information bubble, despite fears to the contrary, a new research report said Thursday.
Defects in atomically thin semiconductor emit single photons
Researchers at the University of Rochester have shown that defects on an atomically thin semiconductor can produce light-emitting quantum dots. The quantum dots serve as a source of single photons and could be useful for ...
