Quantum dots provide complete control of photons

By emitting photons from a quantum dot at the top of a micropyramid, researchers at Linköping University are creating a polarized light source for such things as energy-saving computer screens and wiretap-proof communications.

NSA eyes encryption-breaking 'quantum' machine

The US National Security Agency is making strides toward building a "quantum computer" that could break nearly any kind of encryption, The Washington Post reported Thursday.

Researchers test quantum encryption hacking risk

(Phys.org) —Quantum communication systems offer the promise of virtually unbreakable encryption. Unlike classical encryption, which is used to send secure data over networks today and whose security depends on the difficulty ...

'Spooky action at a distance' aboard the ISS

(Phys.org) —Albert Einstein famously described quantum entanglement as "spooky action at distance"; however, up until now experiments that examine this peculiar aspect of physics have been limited to relatively small distances ...

Space race under way to create quantum satellite

In this month's special edition of Physics World, focusing on quantum physics, Thomas Jennewein and Brendon Higgins from the Institute for Quantum Computing at the University of Waterloo, Canada, describe how a quantum space ...
