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 ...

Researchers have found a clever way to make quantum dots, tiny light-emitting crystals, produce streams of perfectly controlled photons without relying on expensive, complex electronics. By using a ...

In one sentence: A quantum dot laser is a semiconductor laser whose gain medium contains nanoscale quantum dots that confine electrons and holes in all three dimensions, producing discrete energy ...

Plastic films that can convert UV light into wavelengths that could supercharge crop growth are one potential use for a groundbreaking material produced from perovskite quantum dots (PeQDs).

Creating entangled photon pairs often requires intense excitation of nonlinear materials or the active manipulation of quantum devices. Now, entanglement between two photons has been created by ...

A team has developed printable, highly efficient light-emitting metasurfaces. In relationships, sharing closer spaces naturally deepens the connection as bonds form and strengthen through increasing ...
