Evolution of Relative Entropy of Coherence for Two Qubits States
In this paper, we calculate relative entropy of coherence of the output state of two qubits X states with 5 parameters when one subsystem or two subsystems goes through the amplitude damping channel n times. We find that relative entropy of coherence of the output state decreases as the parameter g...

| description | In this paper, we calculate relative entropy of coherence of the output state of two qubits
X
states with 5 parameters when one subsystem or two subsystems goes through the amplitude damping channel
n
times. We find that relative entropy of coherence of the output state decreases as the parameter
g
of the amplitude damping channel continuously changes from zero to one no matter how much
n
is. The curvature of relative entropy of coherence for the output state loosely increases gradually as
n
increases. Furthermore when
n
is larger, frozen coherence can appear as the parameter
g
of the amplitude damping channel increases. |
