任意光子偏振态的确定性远程制备

Deterministic remote preparation of arbitrary photon polarization states

Wei Wu, Wei-Tao Liu, Ping-Xing Chen, Cheng-Zu Li

摘要:

提出了一种利用纠缠、局域操作和经典通信的光子偏振量子比特态的确定性远程态制备方案。通过消耗一个最大纠缠态和两个经典比特,可以在远程位置确定性地制备任意(纯或混合)量子比特态。我们通过远程制备12个纯态和6个混合态的实验证明了这个方案。期望状态和实现状态之间的有序度均高于0.99,平均值为0.9947。

英文摘要:

We propose a deterministic remote state preparation scheme for photon polarization qubit states, where entanglement, local operations and classical communication are used. By consuming one maximally entangled state and two classical bits, an arbitrary (either pure or mixed) qubit state can be prepared deterministically at a remote location. We experimentally demonstrate the scheme by remotely preparing 12 pure states and 6 mixed states. The fidelities between the desired and achieved states are all higher than 0.99 and have an average of 0.9947.
