光场的压缩状态在 20 世纪 70 年代初期得到了理论上的描述，并在 20 世纪 80 年代中期首次被观测到。压缩态的测量光子数与同一系综的所有其他压缩态的测量光子数相关，提供亚泊松统计。如今，所有引力波天文台都使用压缩光作为进一步扩大光功率的经济高效的替代方案。量子关联的这种用户应用是通过 2002 年至 2010 年间对压缩光的专门研究和开发而实现的。
Squeezed states of the optical field were theoretically described in the early 1970s and first observed in the mid 1980s. The measured photon number of a squeezed state is correlated with the measured photon numbers of all other squeezed states of the same ensemble, providing sub-Poissonian statistics. Today all gravitational-wave observatories use squeezed light as the cost-efficient alternative to further scaling up the light power. This user application of quantum correlations was made possible through dedicated research and development of squeezed light between 2002 and 2010.
