Entangled LED first to operate in the telecom window

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. ...

Scientists discover how to distinguish beams of entangled photons

A team from the Faculty of Physics, MSU, has developed a method for creating two beams of entangled photons to measure the delay between them. In the future the results of the study may be used in high-precision measurements, ...

Fingerprints of quantum entanglement

Quantum entanglement is a key feature of quantum computing. Yet, how can researchers verify that a quantum computer actually incorporates large-scale entanglement? Conventional methods require a large number of repeated measurements, ...
