Continuous-variable quantum-state sharing via quantum disentanglement

Lance, Andrew; Symul, Thomas; Bowen, Warwick P; Sanders, Barry Cyril; Tyc, Tomas; Ralph, Timothy Cameron; Lam, Ping Koy

Description

Quantum-state sharing is a protocol where perfect reconstruction of quantum states is achieved with incomplete or partial information in a multipartite quantum network. Quantum-state sharing allows for secure communication in a quantum network where partial information is lost or acquired by malicious parties. This protocol utilizes entanglement for the secret-state distribution and a class of "quantum disentangling" protocols for the state reconstruction. We demonstrate a quantum-state sharing...[Show more]
