For the first time, researchers in China have demonstrated how quantum dots can be engineered to consistently generate pairs of entangled photons. By carefully tailoring the photonic environment ...

Over the past decade, researchers have become good at creating devices that emit single ...

Physicists at the Max Planck Institute have developed an efficient new method to drive the quantum entanglement of photons, and demonstrated it by entangling a record number of photons. The technique ...

Photons, the elementary particles that make up light, are known to be fast, weightless and to not interact with each other. But in new experiments, physicists at MIT and Harvard have now created a new ...

A team of optics researchers has demonstrated the first-ever nonmagnetic topological insulator laser, a finding that has the potential to substantially improve the efficiency, beam quality, and ...

Using an organic solution as a gain medium, US researchers have observed stimulated emission by direct three-photon excitation for the first time. This breakthrough promises to find applications ...
