| Abstract: | The entropy squeezing of an atom with a k-photon in the
Jaynes--Cummings model is investigated. For comparison, we also
study the corresponding variance squeezing and atomic inversion.
Analytical results show that entropy squeezing is preferable
to variance squeezing for zero atomic inversion. Moreover, for
initial conditions of the system the relation between squeezing and
photon transition number is also discussed. This provides a
theoretical approach to finding out the optimal entropy squeezing. |
