can a maximally entangled state undergo unitary time evolution to another maximally entangled state?
... unitary time evolution then at a certain time t0<t<t1 the entanglement content of the state(at time t ) will not be maximal if we consider the S(tr_{A}(\rho_{AB})) as our measure of entanglement. So can we have this process in which our physical resource ...
