Anonymously protocols over classical networks have been achieved and implemented for long, but similar protocols for quantum networks have been still in development so far because facing implementation issues.
The researchers team from the University of Oxford, MIT, Sorbonne University, the University of Paris and CNRS, have proposed the first practical protocol for anonymous communication in quantum networks.
The concept is based on entangled quantum state called the Greenberger-Horne-Zeilinger (GHZ) state. The ability of the protocol to achieve perfect anonymity depends on the players performing perfect actions and sharing a perfect GHZ state. (Phys.org)
