NASA demos CubeSat laser communications capability

Two NASA CubeSats teamed up on an impromptu optical, or laser, communications pointing experiment. The laser beam is seen as a brief flash of light close to the center of the focal plane, to the left of Earth's horizon.

Quantum optical cooling of nanoparticles

When a particle is completely isolated from its environment, the laws of quantum physics start to play a crucial role. One important requirement to see quantum effects is to remove all thermal energy from the particle motion, ...

A long-sighted laser beam

Sometimes, opportunities fall into our laps when we're least expecting them. A team of CERN surveyors, in collaboration with the Institute of Plasma Physics in Prague (IPP), has developed a pioneering laser beam while working ...

Nonlinear integrated quantum electro-optic circuits

Physicists envision that the future of quantum computation networks will contain scalable, monolithic circuits, which include advanced functionalities on a single physical substrate. While substantial progress has already ...

Scientists move quantum optic networks a step closer to reality

Scientists have moved quantum optic networks a step closer to reality. The ability to precisely control the interactions of light and matter at the nanoscale could help such a network transmit larger amounts of data more ...
