Using Game Theory Physicists Shown How Bosons Can Form Multiple Groups

Quantum particles behave in strange ways and are often difficult to study experimentally. Using mathematical methods drawn from game theory, physicists of Ludwig-Maximilias-Universitaet (LMU) in Munich have shown how bosons, which like to enter the same state, can form multiple groups.

Quantum Correlated Light Beams Help Overcome Fundamental Detection Limit of Microcantilever-Based Sensors

Thermal imaging, microscopy and ultra-trace sensing could take a quantum leap with a technique developed by researchers at the Department of Energy’s Oak Ridge National Laboratory.

Astronomers Spot 11 Galaxies Exiled From Their Clusters

We know of about two dozen runaway stars, and have even found one runaway star cluster escaping its galaxy forever. Now, astronomers have spotted 11 runaway galaxies that have been flung out of their homes to wander the void of intergalactic space.

Students Successfully Image Photons Forming Pairs

In the quantum world of light, being distinguishable means staying lonely. Only those photons that are indistinguishable can wind up in a pair, through what is called Hong-Ou-Mandel interference. This subtle quantum effect has been successfully imaged for the first time by two doctoral students from the Faculty of Physics at the University of Warsaw.

New Quantum Engineering Technology Labs at University of Bristol

The University of Bristol has today launched its new state-of-the-art Quantum Engineering Technology (QET) Labs. The QET Labs will provide unique world-leading facilities, bringing together industrial and academic collaborators to build devices that span numerous areas of quantum technology development from the nano-fabrication of quantum devices to a city-scale Quantum Key Distribution network.

Researchers Design All-Photonic Quantum Repeaters for Quantum Cryptography

Imagine having your MRI results sent directly to your phone, with no concern over the security of your private health data. Or knowing your financial information was safe on a server halfway around the world. Or sending highly sensitive business correspondence, without worrying that it would fall into the wrong hands.

Light Brought to a Standstill by Coupling Atoms to Glass Fibers

Light is an extremely useful tool for quantum communication, but it has one major disadvantage: it usually travels at the speed of light and cannot be kept in place.
