Abstract

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.
