一种混合的长距离纠缠分布协议

A Hybrid Long-Distance Entanglement Distribution Protocol

Jonatan B. Brask, Ioannes Rigas, Eugene S. Polzik, Ulrik L. Andersen, Anders S. Sorensen

摘要:

我们提出了一个混合(连续离散变量)量子中继协议的纠缠分布在长距离。从通过单光子探测产生的纠缠态开始,我们展示了如何通过光的零差探测产生纠缠相干态叠加,也称为“薛定谔猫态”。我们表明,仅使用线性光学和零差探测器就可以实现与此类状态的近确定性纠缠交换,并且我们评估了结合这些元素的协议的性能。

英文摘要:

We propose a hybrid (continuous-discrete variable) quantum repeater protocol for distribution of entanglement over long distances. Starting from entangled states created by means of single-photon detection, we show how entangled coherent state superpositions, also known as `Schrödinger cat states', can be generated by means of homodyne detection of light. We show that near-deterministic entanglement swapping with such states is possible using only linear optics and homodyne detectors, and we evaluate the performance of our protocol combining these elements.
