论文摘要
提出了一种干涉安排，其中实现了弱值扩增的技术，以扩大单个光子对光腔的可移动镜的四倍体的影响。光子通过辐射压力与镜像弱相互作用，并在干涉仪的黑暗端口进行后选择。角动量型光子算子的弱值的真实和虚构部分会产生镜子四倍体的扩增，与考虑所有光子的考虑相比，这是很大的，即当不执行未执行后序列的情况时。研究了在热和相干状态初始初始化的镜子的效果。对于热状态，弱值扩增效果会随镜子的颗粒数量而增强，这是由于弱值的假想部分而发生的。
An interferometric arrangement is proposed in which the technique of weak value amplification is implemented in order to enlarge the effect of a single photon on the quadratures of a movable mirror of an optical cavity. The photon interacts weakly with the mirror via radiation pressure and is post-selected in the dark port of the interferometer. The real and imaginary parts of weak values of angular momentum type photonic operators produce an amplification of the mirror quadratures, which is large as compared to the scenario in which all photons are taken into consideration, i.e. when no post-selection is performed. The effect is studied both for a mirror initialized in a thermal and coherent states. For a thermal state, the weak value amplification effect is boosted with the number of particles of the mirror, which occurs due to the imaginary part of the weak values.
