Remote Preparation of Multipartite Equatorial Entangled States in High Dimensions with Three Parties
HOU Kui WANG Jing SHI Shou-Hua 《理论物理通讯》2009,51(4):641-647
A scheme for probabilistic remotely preparing N-particle d-dimensional equatorial entangled states via entangled swapping with three parties is presented. The quantum channel is composed of N - 1 pairs of bipartite d-dimensional non-maximally entangled states and a tripartite d-dimension non-maximally entangled state. It is shown that the sender can help either of the two receivers to remotely prepare the original state, and the N-particle projective measurement and the generalized Hadamard transformation are needed in this scheme. The total success probability and classical communication cost are calculated. 相似文献

Classical Communication Cost and Probabilistic Remote Preparation of Four-Particle Entangled W State
HOU Kui SHI Shou-Hua 《理论物理通讯》2009,51(3):411-418
We present a scheme for probabilistic remote preparation of the four-particle entangled W state by using four partial entangled two-particle states as the quantum channel. In this scheme, if Alice (sender) performs four-particle projective measurements and Bob (receiver) adopts some appropriate unitary operation, the remote state preparation can be successfully realized with certain probability. The classical communication cost is also calculated. However, the success probability of preparation can be increased to 1 for four kinds of special states. 相似文献
