用受激发射直接测量光子对的时间模

Direct temporal mode measurement of photon pairs by stimulated emission

Xin Chen, Xiaoying Li, Z. Y. Ou

摘要:

脉冲泵浦自发参量过程产生的光子对可以用独立的时间模描述,并形成多时间模纠缠态。然而,时间模式的确切形式是不知道的,即使联合光谱强度的光子对可以测量的方法,受激发射层析成像。本文提出了一种反馈迭代方法,它与受激发射方法相结合,可以得到时间纠缠光子对的独立时间模的精确形式。

英文摘要:

It is known that photon pairs generated from pulse-pumped spontaneous parametric processes can be described by independent temporal modes and form a multi-temporal mode entangled state. However, the exact form of the temporal modes is not known even though the joint spectral intensity of photon pairs can be measured by the method of stimulated emission tomography. In this paper, we describe a feedback-iteration method which, combined with the stimulated emission method, can give rise to the exact forms of the independent temporal modes for the temporally entangled photon pairs.
