- Abstract: The properties of open quantum system in quantum information science is now
extensively investigated more generally by the research community as a
fundamental issue for a variety of applications. Usually, the states of the
open quantum system might be disturbed by the decoherence which will reduce the
fidelity in the quantum information processing. So it is better to eliminate
the influence of the environment. However, as part of the composite system,
rational use of the environment system could be beneficial to quantum
information processing. Here we theoretically studied the environment induced
quantum nonlinearity and energy spectrum tuning method in the optomechanical
system. And we found that the dissipation coupling of the hybrid dissipation
and dispersion optomechanical system can induce the coupling between the
environment and system in the cross- Kerr interaction form. When the symmetry
is broken with a directional pumping environment, the system exhibits the
non-reciprocal behavior during the photon excitation and photon blockade for
the clockwise and counterclockwise modes of the whispering-gallery mode
microcavity. Furthermore, we believe that the cross-Kerr coupling can also be
used in a more widely region in quantum information processing and quantum
simulation.
