量子询问逻辑门

Quantum interrogation logic gates

Juan Carlos Garcia-Escartin, Pedro Chamorro-Posada

摘要:

量子询问可以作为量子信息的基本资源。本文介绍了它在纠缠产生和光量子计算中的应用。从光子到粒子的量子询问CZ门出发,推导出三种光学CNOT门。这些门是非破坏性的,并且可以以任意接近1的概率工作。一个可能的实验实现与原子系综进行了讨论。

英文摘要:

Quantum interrogation can be used as a basic resource for quantum information. This paper presents its applications to entanglement creation and to optical quantum computation. The starting point will be a photon to particle quantum interrogation CZ gate, from which three families of optical CNOT gates will be derived. These gates are nondestructive and can work with probabilities arbitrarily close to 1. A possible experimental implementation with atomic ensembles is also discussed.
