Cavity-Assisted Entanglement Generation between Spins and Photon Pulses — •Ferdinand Omlor, Benedikt Tissot, and Guido Burkard — Department of Physics, University of Konstanz, D-78457 Konstanz, Germany

The reliable entanglement generation between distant nodes of a quantum network is a core challenge for the realization of quantum communication. Spin qubits contained in optical cavities are promising systems which can be interconnected by photons using fiber optics. So far the focus of theoretical studies was on single modes. We present a way to study multimode signals, in particular pulses of finite duration. This multimode character needs to be taken into account to correctly calculate the fidelity of entanglement generation between a single photon pulse and a spin qubit. We specifically study this with the network architecture proposed by K. Nemoto et al., Phys. Rev. X 4, 031022 (2014) in mind.
