Abstract: | This paper studies the dynamics of nonlocality for a bosonic
entangled coherent state in a phase damping model. The density
operator of the system is solved by using a superoperator method.
The dynamics of nonlocality for the bosonic entangled coherent state
is uncovered by the Bell operator based on the pseudospin operator
of a light field. The dynamics of the nonlocality for this state has
also been studied by other Bell operators. The result of the
numerical calculations of the Bell function shows that the quantum
nonlocality heavily depends on the chosen Bell operator. |
