论文摘要
在这封信中，我们提出了一种纠缠光子对量子层析成像中的深度计数校正方法。该框架基于黑暗计数的线性模型，该模型施加在测量形式上。该方法是根据从极化输入光子实验得出的经验数据测试的。我们证明，黑暗计数校正的数值方法可确保与标准估计相比更可靠的状态重建。然而，最重要的是，与实验技术相比，在概念上简单的理论方法在纠缠量化方面更有效。
In this letter, we propose a method of dark count correction in quantum state tomography of entangled photon pairs. The framework is based on a linear model of dark counts, which is imposed on the measurement formalism. The method is tested on empirical data derived from an experiment on polarization-entangled photons. We demonstrate that the numerical approach to dark count correction guarantees more reliable state reconstruction compared with standard estimation. Most importantly, however, the conceptually simple theoretical approach proves to be more efficient at entanglement quantification than experimental techniques.
