Phys. Rev. A 82, 022321 (2010) [10 pages]Coherent-state control of noninteracting quantum entanglementReceived 1 October 2009; published 19 August 2010 We exploit a novel approximation scheme to obtain a new and compact formula for the parameters underlying coherent-state control of the evolution of a pair of entangled two-level systems. It is appropriate for long times and for relatively strong external quantum control via coherent-state irradiation. We take account of both discrete-state and continuous-variable degrees of freedom. The formula predicts the relative heights of entanglement revivals and their timing and duration. © 2010 The American Physical Society URL:
