Researchers have demonstrated the first quantum light-emitting diode (LED) that emits single photons and entangled photon pairs with a wavelength of around 1550 nm, which lies within the standard telecommunications window. ...
(PhysOrg.com) -- Many scientists believe that quantum entanglement is required in order for effective quantum computing. Entanglement takes place when there is a connection that exists between two objects - even when they ...
Scientists from the Russian Quantum Center (Moscow), lead by Prof. Alexander Lvovsky, have developed a method to restore quantum entanglement and have tested this method in an experiment. This research significantly broadens ...

(Phys.org) —While two-photon interference is an important way of entangling independent identical photons, it does not handle different-color photons with the same aplomb. Recently, scientists at the University of Science ...
Members of the Faculty of Physics at the Lomonosov Moscow State University have elaborated a new technique for creating entangled photon states. They have described their research in an article published in the journal Physical ...
