Non-Markovian effects in waveguide-mediated entanglement
C Gonzalez-Ballestero, F J García-Vidal, Esteban Moreno · New Journal of Physics · 2013
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 We show that when the qubit–waveguide coupling is increased, the Markov approximation is no longer valid, and the generation of entanglement is worsened.
