Latest Quantum cryptography Stories
Atomic antennae transmit quantum information across a microchip.
Scientists have moved a step closer to creating quantum computers by generating 10 billion bits of quantum entanglement in silicon for the first time.
Discovery moves quantum networks closer to reality.
When the military needs to send the key to encrypted data across the world, it can't necessarily rely on today's communication lines, where the message could be covertly intercepted.
Physicists at UC Santa Barbara have succeeded in combining laser light with trapped electrons to detect and control the electrons' fragile quantum state without erasing it.
An international research group led by scientists from the University of Bristol has developed a new approach to quantum computing that could soon be used to perform complex calculations that cannot be done by today's computers.
Tokyo, Sept 10, 2010 - (JCN Newswire) - Institute for Nano Quantum Information Electronics, The University of Tokyo (Director: Yasuhiko Arakawa), Fujitsu Laboratories Limited, and NEC Corporation today announced that they have achieved quantum cryptographic key distribution(1) at a world-record distance of 50 km using transmission from a single-photon emitter(2).
The Norwegian University of Science and Technology (NTNU) and the University of Erlangen-NÃ¼rnberg together with the Max Planck Institute for the Science of Light in Erlangen have recently developed and tested a technique exploiting imperfections in quantum cryptography systems to implement an attack.
Physicists demonstrate means for quantum bits to communicate over long distances.
A quantum particle is hard to grasp, because one cannot determine all its properties precisely at the same time.
