Optical Data Transport for Faster Computers and Ultra-Secure Quantum Communications

Stanford electrical engineer Jelena Vuckovic wants to make computers faster and more efficient by reinventing how they send data back and forth between chips, where the work is done.

JQI Researchers Study Magnetization Dynamics in Checkerboard Optical Lattice

Physicists use theoretical and experimental techniques to develop explanations of the goings-on in nature. Somewhat surprisingly, many phenomena such as electrical conduction can be explained through relatively simplified mathematical pictures — models that were constructed well before the advent of modern computation. And then there are things in nature that push even the limits of high performance computing and sophisticated experimental tools.

ERC Awards €2.5 Million Grant for Project on Scalable Quantum Photonic Networks

Peter Lodahl, professor and head of the Quantum Photonics research group at the Niels Bohr Institute at the University of Copenhagen, has received a large and prestigious grant from the European Research Council, the ERC Advanced Grant. The grant of just over 18.6 million kroner (2½ million euro) has a duration of five years and is for the project: Scalable Quantum Photonic Networks.

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.
