摘要：

Nonunitary time evolution of an initially highly squeezed state under continuous photon-number measurement is investigated using the quasiprobability distribution. It is found that the measured quantum state bifurcates into two macroscopically distinguishable states upon the detection of a single photon, while preserving purity by feeding back real-time readout information.
