Quantum Cryptography Using Qutrits ... It has been published by the New Journal of Physics under the name "Experimental quantum cryptography with qutrits." Here is an introduction from this paper... In the last decades of the 20th century, cryptography schemes were proposed where the security relies on the laws of quantum mechanics...
Secure Video Conferencing Via Quantum Cryptography ... Here is the introduction from Nature. Scientists from Toshiba's Cambridge Research Laboratory unveiled their invention to business leaders and government officials at Britain's Department of Trade and Industry in London on 27 April....
First Six-Node Quantum Cryptography Network Is Unveiled ... Quantum cryptography has the potential to guarantee perfectly secure communications, but until now all of the prototype systems have been point-to-point links rather than networks that share connections....
New Quantum Cryptography Speed Record ... The demonstration, [which will be described in the May 3 issue of Optics Express,] is the first major reported result from a new NIST testbed built to demonstrate quantum communications technologies and cryptographic key distribution. The testbed provides a measurement and standards infrastructure for research, testing, calibrations and technology development...
