Researchers document a quantum spin wave for light

Researchers at Purdue University have created a quantum spin wave for light. This can be a carrier of information for future nanotechnologies but with a unique twist: they only flow in one direction.

Travelling towards a quantum internet at light speed

A research team lead by Osaka University demonstrated how information encoded in the circular polarization of a laser beam can be translated into the spin state of an electron in a quantum dot, each being a quantum bit and ...

Researchers teleport information within a diamond

Researchers from the Yokohama National University have teleported quantum information securely within the confines of a diamond. The study has big implications for quantum information technology—the future of sharing and ...

New holographic technique opens the way for quantum computation

Photography measures how much light of different color hits the photographic film. However, light is also a wave, and is therefore characterized by the phase. Phase specifies the position of a point within the wave cycle ...

US searches of phones, laptops at airports rising, suit says

U.S. government searches of travelers' cellphones and laptops at airports and border crossings nearly quadrupled since 2015 and are being conducted for reasons beyond customs and immigration enforcement, according to papers ...
