一种类型的未知三粒子GHZ态的辅助概率克隆
Assisted cloning of a class of unknown three-qubit GHZ state
摘要
Abstract
A protocol for probabilistic cloning of a class of three-qubit Greenberger-Horne-Zeilinger (GHZ)state and its orthogonal complement state by using three maximally two-qubit entangled states as the quantum channel is proposed.In this protocol,Bob(the state receiver)can receive theunknown state usual teleportation process.With the assistance of Victor(the state preparer),Alice(the state sender)can produce the perfect copies and complement copies of an unknown state.A protocol for the teleportation is given by using non-maximally entangled states as quantum channel,and the clones and complement clones of unknown state also Can be obtained by Alice with assistance offered by the state preparer.关键词
