受驱动谐振子的量子二分法

Quantum Binary Decision for Driven Harmonic Oscillator

Matteo G. A. Paris

摘要:

我们解决的问题,确定是否谐振子已被扰动的外力。量子探测和估计理论已被用于设计最佳测量方案。计算了振子不同初态准备情况下的探测概率。相应的最小可检测扰动强度的下限已被评估和随机相位扰动的一般界也已被诱导。

英文摘要:

We address the problem of determining whether or not a harmonic oscillator has been perturbed by an external force. Quantum detection and estimation theory has been used in devising optimum measurement schemes. Detection probability has been evaluated for different initial state preparations of oscillator. The corresponding lower bounds on minimum detectable perturbation intensity has been evaluated and a general bound for random phase perturbation has been also induced.
