摘要:

本文研究了由热态减去光子产生的光学量子态。讨论了它们的光子数和正交分布的某些方面,并进行了实验验证。我们展示了一个原始的方法,多达10个光子减去状态的准备与使用只有一个单光子探测器。用平衡零差法测量了所有的态,并重建了相应的密度矩阵。所需状态和重建状态之间的保真度超过99%

英文摘要:

We present a study of optical quantum states generated by subtraction of photons from the thermal state. Some aspects of their photon number and quadrature distributions are discussed and checked experimentally. We demonstrate an original method of up to ten photon subtracted state preparation with use of just one single-photon detector. All the states where measured with use of balanced homodyne technique, and the corresponding density matrices where reconstructed. The fidelity between desired and reconstructed states exceeds 99%
