量子“猜我的号码”协议的拟议实验

Proposed experiment for the quantum "Guess my number" protocol

Adan Cabello, Antonio J. Lopez-Tarrida

摘要:

Steane和van Dam提出了一个实验性的实现方案,利用纠缠辅助的“猜我的号码”协议来降低通信复杂性,该方案需要产生和检测效率eta > 0.70的三量子比特GHZ态,这需要效率sigma > 0.89的单光子探测器。我们提出了一个修改的协议,可以转化为一个真正的实验,使用当今的技术。在所提出的实验中,多方通信复杂性的量子降低将需要效率eta > 0.05,对于四方,可以使用sigma > 0.47的检测器实现,并且对于三方,eta > 0.17(sigma > 0.55)。

英文摘要:

An experimental realization of the entanglement-assisted "Guess my number" protocol for the reduction of communication complexity, introduced by Steane and van Dam, would require producing and detecting three-qubit GHZ states with an efficiency eta > 0.70, which would require single photon detectors of efficiency sigma > 0.89. We propose a modification of the protocol which can be translated into a real experiment using present-day technology. In the proposed experiment, the quantum reduction of the multi-party communication complexity would require an efficiency eta > 0.05, achievable with detectors of sigma > 0.47, for four parties, and eta > 0.17 (sigma > 0.55) for three parties.
