Abstract
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.
