单光子量子比特概率量子编码器

Probabilistic Quantum Encoder for Single-Photon Qubits

T. B. Pittman, B. C Jacobs, J. D. Franson

摘要:

我们描述了一个实验,其中一个物理量子比特表示的偏振状态的单光子的概率编码的逻辑状态的两个光子。该实验依赖于线性光学、后选择和由参量下转换光子对和弱相干态产生的三光子干涉效应。编码操作的一个有趣结果是能够观察到纠缠的三光子Greenberger-Horne-Zeilinger态。

英文摘要:

We describe an experiment in which a physical qubit represented by the polarization state of a single-photon was probabilistically encoded in the logical state of two photons. The experiment relied on linear optics, post-selection, and three-photon interference effects produced by a parametric down-conversion photon pair and a weak coherent state. An interesting consequence of the encoding operation was the ability to observe entangled three-photon Greenberger-Horne-Zeilinger states.
