    • According to each embodiment of the present invention, a phase-correlation can be generated between respective laser fields produced by a plurality of independent lasers. Specifically, based on a structure that first and second laser fields each having a mixed quantum state represented by a single-mode Glauber coherent state that a phase is completely indeterminate are mixed with each other and a quantum continuous measurement is performed by causing absorbers to individually cross two output quantum states, the phase-correlation can be generated between the first and second laser fields when absorption by the absorbers massively occurs in one of the two quantum states as a result of the quantum continuous measurement.
    • 根据本发明的每个实施例,可以在由多个独立激光器产生的各个激光场之间产生相位相关。 具体而言,基于以相位完全不确定的单模Glauber相干状态表示的具有混合量子态的第一激光场和第二激光场彼此混合的结构,并且通过使吸收体分别进行量子连续测量 通过交叉两个输出量子态,当吸收体的吸收作为量子连续测量的结果在两个量子态之一中大量发生时,可以在第一和第二激光场之间产生相位相关。
