Discovery of pure organic substances exhibiting the quantum spin liquid state
Researchers at the University of Tokyo and Japan's National Institute for Materials Science have discovered pure organic substances exhibiting the quantum spin liquid state.
Physicists find way to boot up quantum computers 72 times faster than previously possible
Press the start button, switch on the monitor, grab a cup of coffee and off you go. That is pretty much how most us experience booting up a computer. But with a quantum computer the situation is very different. ...
Experimentally testing nonlocality in many-body systems
In a recent study published in Science, researchers at ICFO construct multipartite Bell inequalities built from the easiest-to-measure quantities, the two-body correlators, which are capable of revealing ...
Independent research group testing D-Wave Two finds no quantum speedup
Simulating time travel: Doctor Who meets Professor Heisenberg
(Phys.org)—University of Queensland researchers have simulated time travel using light particles. Lead author and PhD student Martin Ringbauer, from UQ's School of Mathematics and Physics, said the study ...
New approach may be key to quantum dot solar cells with real gains in efficiency
(Phys.org) —Los Alamos researchers have demonstrated an almost four-fold boost of the carrier multiplication yield with nanoengineered quantum dots. Carrier multiplication is when a single photon can excite ...
Study finds 'lumpy' universe cannot explain cosmic acceleration
(Phys.org) —Astrophysicists at The University of Texas at Dallas are helping to better define the nature of the cosmos by examining why the universe appears to be expanding at an accelerating pace.
Graphene quantum dot flash memories look promising for data storage
A new model for quantum noise
The National Physical Laboratory (NPL) has published research in Nature Communications that updates one of the most fundamental concepts in the physics of quantum electronic devices - the standard tunnel ...
To test the effect of gravity on quantum entanglement, we need to go to space
There is an up-and-coming set of technologies that uses the strange properties of atomic particles predicted by the theory of quantum mechanics, which is the physics of the very small stuff. This technology ...
Physicists propose way to use quantum bidding in bridge
Strange physics turns off laser
Inspired by anomalies that arise in certain mathematical equations, researchers have demonstrated a laser system that paradoxically turns off when more power is added rather than becoming continuously brighter.
Ultra-thin wires for quantum computing
Take a fine strand of silica fiber, attach it at each end to a slow-turning motor, gently torture it over an unflickering flame until it just about reaches its melting point and then pull it apart. The middle ...
Quantum theory reveals puzzling pattern in how people respond to some surveys
Researchers used quantum theory – usually invoked to describe the actions of subatomic particles – to identify an unexpected and strange pattern in how people respond to survey questions.
