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 ...

Add Yahoo as a preferred source to see more of our stories on Google. A yin-yang-like shape made of pink and green dots shows two particles in a state of quantum entanglement Scientists have used a ...

Entangled photons can be used to improve imaging and measurement techniques. A team of researchers from the Fraunhofer Institute for Applied Optics and Precision Engineering IOF in Jena has developed ...

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 ...

Quantum manipulation: The squeezer – an optical parametric oscillator (OPO) that uses a nonlinear crystal inside an optical cavity to manipulate the quantum fluctuations of light – is responsible for ...

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”) ...

Entangled light sources are considered as core technology for multiple quantum network architectures. Of particular interest are sources that are based on a single quantum system as these offer ...

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 ...

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.

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 ...
