Multiparty Remote State Preparation With Linear Optical Elements

Abstract

We present a linear optical protocol for multiparty remote state preparation (MRSP) in terms of optical elements. MRPS is a procedure for multiparty collaboration with each other to remote preparation of a known quantum state to a distant party. We show that it is possible to achieve unity fidelity remote preparation of the polarization state using optical elements. This protocol may be used for converging the split information at one point.

Improving the Success Probability of Remote State Preparation by Using Partial Classical Knowledge

“…That is, in detail, if Bob knows , the total success probability of RSP will be given by Eq. (19); if Bob knows ', the total success probability of RSP will be 2b 2 .…”

Deterministic joint remote state preparation via partially entangled quantum channel

“…[8][9][10][11][12][13][14][15] In general, maximally entangled quantum channels guarantee the achievement of deterministic JRSP. [16][17][18][19][20] Nevertheless, due to the inevitable interaction between the quantum channel and its surrounding environments, it is challenging to prepare and distribute maximally entangled states.…”

Joint remote state preparation of a qubit state via a W state using single-atom rotation operations

“…Soon after, the JRSP schemes for various quantum states via different types of quantum channel have been reported [33]- [41]. However, to our knowledge, there is a few works for realizing JRSP in real physical system [31], [42].…”
