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 ...

A team of physicists has uncovered a surprising new way to explore one of science's greatest challenges: uniting the two fundamental theories that explain how our universe works—Einstein's theory of ...

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

Photonic Router: a 2-by-2 device that guides input photons to any one of the output ports with control signals. Imagine the benefits if the entire internet got a game-changing upgrade to speed and ...

The experimental layout of the sender Alice and the receiver Bob. Alice’s setup contains the excitation and collection setup of the single photon source, and a Sagnac-like polarization modulator for ...

Scientists have developed a new way to manufacture semiconductor quantum dots that emit faster ...

A method to make quantum dots lets them release single photons. The approach could support quantum communication systems.

Light is an unusually rich carrier of information. Its direction of travel, wavelength, and polarization can all be used to encode signals or images ...

Imagine the benefits if the entire internet got a game-changing upgrade to speed and security. This is the promise of the quantum internet—an advanced system that uses single photons to operate.
