Faithful sharing of multipartite entanglement over noisy quantum channels
Soojoon Lee, Sora Choi, Dong Pyo Chi
abstract: We present a protocol in which two or more parties can share multipartite
entanglement over noisy quantum channels. The protocol is based on the
entanglement purification presented by Shor and Preskill [Phys. Rev. Lett. 85,
441 (2000)] and the quantum teleportation via an isotropic state. We show that
a nearly perfect purification implies a nearly perfect sharing of multipartite
entanglement between two parties so that the protocol can assure a faithful
sharing of multipartite entanglement with Shor and Preskill's proof on the
entanglement purification.
