Non-Markovian effects in waveguide-mediated entanglement    [PDF]

C. Gonzalez-Ballestero, F. J. Garcia-Vidal, Esteban Moreno

We study the generation and evolution of entanglement between two qubits coupled through one-dimensional waveguide modes. By using a complete quantum electrodynamical formalism we go beyond the Markovian approximation. The diagonalization of the hamiltonian is carried out, and a set of quasi-localized eigenstates is found. We show that when the qubit-waveguide coupling is increased, the Markov approximation is not anymore valid, and the generation of entanglement is worsened.
