论文摘要
我们为在干涉光谱设置中纠缠的光子对诱导的时间分辨光子计数信号开发了闭合表达式。 Liouville空间中的超级操纵器表达式被得出，可以解释耦合到浴缸引起的放松和脱落。干涉测量设置在非琐事上混合了物质和光变量，这使他们的解释变得复杂。我们为此设置提供了直观的模块化框架，以简化其描述。基于检测阶段和光 - 物质相互作用过程之间的分离。我们表明，对纠缠时间和干涉时间变化控制观察到的物理时间尺度。只有少数过程就样本响应的纠缠时间较小的限制案例造成了贡献，并且可以挑出具体的贡献。
We develop closed expressions for a time-resolved photon counting signal induced by an entangled photon pair in an interferometric spectroscopy setup. Superoperator expressions in Liouville-space are derived that can account for relaxation and dephasing induced by coupling to a bath. Interferometric setups mix matter and light variables non-trivially, which complicates their interpretation. We provide an intuitive modular framework for this setup that simplifies its description. Based on separation between the detection stage and the light-matter interaction processes. We show that the pair entanglement time and the interferometric time-variables control the observed physics time-scale. Only a few processes contribute in the limiting case of small entanglement time with respect to the sample response, and specific contributions can be singled out.
