Nonlocal quantum memory effects in a correlated multimode field
We review the model of two qubits coupled locally to an environment which consists of nonlocally correlated field modes [Phys. Rev.Lett. 108, 210402 (2012)]. We derive the correct expressions for the reduced dynamics of the two-qubit system and demonstrate that strong nonlocal memory effects are ind...

| Zusammenfassung: | We review the model of two qubits coupled locally to an environment which
consists of nonlocally correlated field modes [Phys. Rev.Lett. 108, 210402
(2012)]. We derive the correct expressions for the reduced dynamics of the
two-qubit system and demonstrate that strong nonlocal memory effects are indeed
present for suitable initial EPR-type Gaussian environmental states. |
