Quantum Secret Sharing Schemes and Reversibility of Quantum Operations

Tomohiro Ogawa, Akira Sasaki, Mitsugu Iwamoto +1

Quantum secret sharing schemes encrypting a quantum state into a multipartite entangled state are treated. The lower bound on the dimension of each share given by Gottesman [Phys.…
