光子计数实验中量子相空间采样的精度

Accuracy of Sampling Quantum Phase Space in Photon Counting Experiment

Konrad Banaszek, Krzysztof Wodkiewicz

摘要:

通过光子计数实验研究了确定单个量子化光模相空间准分布的准确性。我们推导出一个精确的分析公式的实验结果的误差。这一结果提供了一个估计的实验参数,如事件的数量,需要确定的quasidistribution与假设的精度。我们的分析还表明,它是在一般情况下,不可能补偿的光电探测器在实验数据的数值处理的不稳定性。用蒙特卡罗模拟对相干态、单光子Fock态和薛定谔猫态的光子计数实验进行了讨论。

英文摘要:

We study the accuracy of determining the phase space quasidistribution of a single quantized light mode by a photon counting experiment. We derive an exact analytical formula for the error of the experimental outcome. This result provides an estimation for the experimental parameters, such as the number of events, required to determine the quasidistribution with assumed precision. Our analysis also shows that it is in general not possible to compensate the imperfectness of the photodetector in a numerical processing of the experimental data. The discussion is illustrated with Monte Carlo simulations of the photon counting experiment for the coherent state, the one photon Fock state, and the Schroedinger cat state.
