Abstract

The problem of formation of macroscopic (mesoscopic) coherent superposition of polarization states for boson-like systems are discussed for the first time. The quantum interference of two (and/or more) coherent states in boson systems results in nonclassical polarization states being described by us by different way: the Wigner quasi- distribution function, boson statistics and entropy of quantum states. The phase transition from classical to quantum state of the system in such a `frozen' mesoscopic system (quantum dots) is obtained. The behavior of the Wigner function under the phase transitino demonstrates the fractal-like structure. The application of considered coherent superposition of quantum states and induced phase transition in mesoscopic systems to construction of the quantum logical gates for quantum computation are discussed as well.
