A team of physicists has designed quantum algorithms that can model one of the most elusive behaviors in nature: a photon ...

In January, a team led by Jim Schuck, professor of mechanical engineering at Columbia Engineering, developed a method for creating entangled photon pairs, a critical component of emerging quantum ...

A photon enters a tiny disk of layered crystal no wider than a human hair. It circles the rim, bouncing along atomically ...

Emerging technologies for non-line-of-sight imaging can detect objects even if they are around a corner or behind a wall. In new work, researchers use a new type of detector to extend this method from ...

Schematic diagram and microscopic observation of an optical fiber doped with rare-earth atoms. The fluorescence from the entire optical fiber can be seen. (b) Schematic diagram and microscopic ...

Researchers have developed a new technique to detect photons -- elementary particles that span from visible light to radio frequencies and are instrumental in carrying cellular communication. The ...

A photon emitted from a star a billion light-years away arrives at a telescope having experienced no time whatsoever. Not ...
