Space-borne quantum source to secure communication

Soon, powerful quantum computers will be able to easily crack conventional mathematically encrypted codes. Entangled photons generated by a spaceborne quantum source could enable hack-proof key exchange for ultra high security ...

Tracking down the mystery of entangled particles of light

Bernese researchers have taken an important step towards new measurement methods such as quantum spectroscopy. In an experiment, they succeeded in uncovering part of the mystery surrounding the so-called "entangled photons" ...

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. ...

Unbreakable quantum entanglement

Einstein's "spooky action at a distance" persists even at high accelerations, researchers of the Austrian Academy of Sciences and the University of Vienna were able to show in a new experiment. A source of entangled photon ...

New records set up with 'screws of light'

University of Vienna research team has succeeded in breaking two novel records while experimenting with so-called twisted particles of light. These results, now published in the journal PNAS, are not only of fundamental interest ...

Producing spin-entangled electrons

A team from the RIKEN Center for Emergent Matter Science, along with collaborators from several Japanese institutions, have successfully produced pairs of spin-entangled electrons and demonstrated, for the first time, that ...
