摘要:

我们报道了利用远距离通信波长的光子进行四光子量子干涉的实验演示。实现多光子量子干涉是实现线性光学量子信息处理和基于测量的量子计算的关键。我们已经开发了一种源,有效地发射光子对在一个纯粹的spectrotemporal模式在电信波长区域,并已证明了量子干涉表现出减少条纹的间隔,对应于减少德布罗意波长的四光子“NOON”状态。我们的研究结果将为利用电信波长的光子进行实际的量子信息处理开辟一条道路。

英文摘要:

We report the experimental demonstration of four-photon quantum interference using telecom-wavelength photons. Realization of multi-photon quantum interference is essential to linear optics quantum information processing and measurement-based quantum computing. We have developed a source that efficiently emits photon pairs in a pure spectrotemporal mode at a telecom wavelength region, and have demonstrated the quantum interference exhibiting the reduced fringe intervals that correspond to the reduced de Broglie wavelength of up to the four photon `NOON' state. Our result should open a path to practical quantum information processing using telecom-wavelength photons.
