Quantum key distribution (QKD) is a technique that enables secure communications between devices using a cryptographic protocol that is partly based on quantum mechanics. This communication method ultimately allows two parties ...
(PhysOrg.com) -- When an optical fiber is bent by 90° or more, the light begins to leak away, posing a problem for fiber optics communications. But by using special lenses that can bend light by not only 90°, but ...
(PhysOrg.com) -- One of the issues associated with quantum information schemes revolves around the ability to develop quantum memories that allow for the retrieval of information on demand. Overcoming this issue is especially ...
(PhysOrg.com) -- Quantum key distribution (QKD) could be the next commercial success of quantum physics, and a recent study has taken the field a step closer to this reality. Researchers from the University of Geneva in Switzerland ...
Han and Leia. George and Amal. Kermit and Miss Piggy. Gomez and Morticia. History's greatest couples rely on communication to make them so strong their power cannot be denied.
