光的多次光的散射引起的量子干涉和纠缠

Quantum interference and entanglement induced by multiple scattering of light

J. R. Ott, N. A. Mortensen, P. Lodahl

摘要:

本文研究了任意数量的光学量子态通过多重散射介质时的量子干涉效应。我们确定了量子干涉对光子关联和两个输出模式之间的连续变量纠缠度的作用。研究表明,量子干涉效应在所有无序集合中平均化后仍然存在,并表现为光子相关性的增加,从而引起光子反聚束。最后,预测了体散斑图中连续变量纠缠关联的存在。我们的研究结果表明,多重散射提供了一个有前途的方式相干干涉许多独立的量子态的光的潜在用途在量子信息处理。

英文摘要:

We report on the effects of quantum interference induced by transmission of an arbitrary number of optical quantum states through a multiple scattering medium. We identify the role of quantum interference on the photon correlations and the degree of continuous variable entanglement between two output modes. It is shown that the effect of quantum interference survives averaging over all ensembles of disorder and manifests itself as increased photon correlations giving rise to photon anti-bunching. Finally, the existence of continuous variable entanglement correlations in a volume speckle pattern is predicted. Our results suggest that multiple scattering provides a promising way of coherently interfering many independent quantum states of light of potential use in quantum information processing.
