量子态层析成像（QST）是评价纠缠光子对质量的一种重要方法，已广泛用于测量偏振纠缠。然而，QST还没有应用到时间盒纠缠中，而时间盒纠缠是一种适合光纤传输的纠缠。在本文中，我们阐明了使用1位延迟干涉仪在时间bin纠缠光子对上实现QST的方法。我们还提供了色散移位光纤中自发四波混频产生的时间bin纠缠光子对的QST的实验结果。(C) 2009年美国光学学会
Quantum state tomography (QST) is an important method for evaluating the quality of entangled photon pairs, and has been widely used to measure polarization entanglement. However, QST has not been applied to time-bin entanglement, which is a type of entanglement suitable for fiber transmission. In this paper, we clarify the way to implement QST on time-bin entangled photon pairs using a 1-bit delayed interferometer. We also provide experimental results for a demonstration of QST for time-bin entangled photon pairs generated using spontaneous four-wave mixing in a dispersion shifted fiber.
