Quantum computing and fundamental limit of self-switching effect for nonlinear spatially inhomogeneous bosonic systems

摘要

The quantum theory of nonlinear dynamics and self-switching effect for two coupled bosonic modes in nonlinear spatially inhomogeneous systems have been developed using Hartree approximation for the first time. The quantum limits of observation of self-switching effect for the polarization characteristics have been founded. We also predict the formation of nonclassical mesoscopic states (Schrodinger cat like states) in such a systems as well. We also propose four-mode interaction in the systems under consideration for quantum XOR and SWAP logic operations.
