Posted by klaurent MIT

Kavli Affiliate: Saul Rappaport | First 5 Authors: Kevin B. Burdge, Kareem El-Badry, Thomas R. Marsh, Saul Rappaport, Warren R. Brown | Summary: In over a thousand known cataclysmic variables (CVs), where a white dwarf is accreting from a hydrogen-rich star, only a dozen have orbital periods below 75 minutes. One way to achieve these […]

Long-Range QKD without Trusted Nodes is Not Possible with Current Technology

Posted by dbos Delft

Kavli Affiliate: Wolfgang Tittel | First 5 Authors: Bruno Huttner, Romain Alléaume, Eleni Diamanti, Florian Fröwis, Philippe Grangier | Summary: A recently published patent (https://www.ipo.gov.uk/p-ipsum/Case/PublicationNumber/GB2590064) has claimed the development of a novel quantum key distribution protocol purporting to achieve long-range quantum security without trusted nodes and without use of quantum repeaters. Here we present a […]
