The concept of quantum entanglement is emblematic of the gap between classical and quantum physics. Referring to a situation in which it is impossible to describe the physics of each photon separately ...

Scientists have pulled off a first: teleporting a photon’s state between two separate quantum dots. This was done over a 270-meter open-air link, proving quantum information can travel between ...

Photon 'time bins' and signal stability show promise for practical quantum communication via fiber optics by Lavinia Meier-Ewert, Leibniz Institute of Photonic Technology edited by Lisa Lock, reviewed ...

Physicists have developed a spectral-filtering technique that strips away unwanted extra photons from quantum light sources, tackling one of the most persistent obstacles in quantum optics. The method ...

The consortium of the BMBF project SPINNING coordinated by Fraunhofer IAF has succeeded in decisively advancing the development of spin-photon-based quantum computers. On October 22 and 23, 2024, the ...

A new platform developed by Illinois Grainger engineers demonstrates the utility of a ytterbium-171 atom array in quantum networking. Their work represents a key step toward long distance quantum ...
