论文摘要
研究了由参数下转换产生的挤压光子状态的制备和观察中时空自由度的作用。分析借助于半古典近似和薄晶近似的功能方法进行。发现挤压状态会随着下转换的效率提高，以取决于确定挤压量的同性恋测量条件的方式，因此失去了最小不确定性。
The role of the spatiotemporal degrees of freedom in the preparation and observation of squeezed photonic states, produced by parametric down-conversion, is investigated. The analysis is done with the aid of a functional approach under the semi-classical approximation and the thin-crystal approximation. It is found that the squeezed state loses its minimum uncertainty property as the efficiency of down-conversion is increased, in a way that depends on the conditions of the homodyne measurements with which the amount of squeezing is determined.
