New approach uses “twisted light” to increase the efficiency of quantum cryptography systems

New approach uses “twisted light” to increase the efficiency of quantum cryptography systems

March 20, 2015

Rochester researchers and their collaborators have developed a way to transfer 2.05 bits per photon by using “twisted light.” The new approach doubles the 1 bit per photon that is possible with current systems that rely on light polarization and could help increase the efficiency of quantum cryptography systems.

The red dwarf star, which has a mass about 8% that of the Sun and is orbited by a ‘brown dwarf’ companion, was discovered in 2013 in images recorded by NASA’s Wide-field Infrared Survey Explorer (WISE) mission. It is relatively nearby, at about 6 parsecs (19.6 light years) away.
