Scientists have used a first-of-its-kind technique to visualize two entangled light particles in real time — making them appear as a stunning quantum "yin-yang" symbol. The new method, called biphoton ...

Researchers at the Cavendish Laboratory in Cambridge and Toshiba Research Europe have produced a new way to produce entangled photons, a key technique for quantum encryption and computing. The ...

Quantum entanglement has long been framed as a strange communication channel between particles, but the latest experiments suggest it can do something more concrete and practical: make light itself ...

Chaotic speckle: a pattern resulting from light being scrambled by a complex medium such as a multimode optical fibre. (Courtesy: M Malik and S Goel) Light passing through a disordered (or “complex”) ...

Driving late at night, you come upon a red light and stop the car. You lift your hand wearily to block the red glow streaming through your windshield. Suddenly, both the green and yellow lights come ...

Cluster creation: artistic impression of a state containing multiple entangled photons. (Courtesy: iStock/agsandrew) Pairs of entangled photons are a key ingredient of photonic quantum computers, ...

Researchers propose an unconventional way to generate light made from entangled photons. In the graphic above, photons meet the electrons of a helium atom, which then emits two entangled photons.

Researchers have revealed the necessary conditions for the robust transport of entangled states of two-photon light in photonic topological insulators, paving the way the towards noise-resistant ...

Tailoring light is much like tailoring cloth, cutting and snipping to turn a bland fabric into one with some desired pattern. In the case of light, the tailoring is usually done in the spatial degrees ...

The stunning experiment, which reconstructs the properties of entangled photons from a 2D interference pattern, could be used to design faster quantum computers. When you purchase through links on our ...
