Researchers at NIST Center for Nanoscale Science and Technology were able to make photons emitted by quantum dots at different frequencies identical to each other by shifting their frequencies to ...

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.

Physicists at the Max Planck Institute of Quantum Optics have managed to entangle more than a dozen photons efficiently and in a defined way. They are thus creating a basis for a new type of quantum ...

Physicists have managed to entangle more than a dozen photons efficiently and in a defined way. They are thus creating a basis for a new type of quantum computer. In order to effectively use a quantum ...

Photons, for centuries both a puzzle and a tool, continue to help scientists illuminate nature at the smallest and largest ...

(Nanowerk News) Physicists at the Max Planck Institute of Quantum Optics have managed to entangle more than a dozen photons efficiently and in a defined way (Nature, "Efficient generation of entangled ...

Quantum systems cannot be cloned - or duplicated - perfectly, but the development of quantum cryptography and computing relies on a knowledge of exactly how well they can be copied. Antia ...

2D projection of the cosmic web as obtained from a supercomputer simulation. CREDIT Dr Ewald Puchwein and the Sherwood-Relics collaboration Dark matter could be made up of ultralight dark photons that ...

An international research team involving Paderborn University has achieved a crucial breakthrough on the road to a quantum ...

A gas made of particles of light, or photons, becomes easier to compress the more you squash it. This strange property could prove useful in making highly sensitive sensors. While gases are normally ...
