Abstract

To establish remote quantum networks, the distribution of entanglement over long distances is required. In order to overcome transmission loss in quantum channels (e.g. optical fibers), quantum repeater architectures have been proposed [1]. The availability of single photons at telecom wavelength entangled with photons stored in long-lived quantum memories for synchronization issues [1] is a crucial resource in this context. In this contribution, we will describe our efforts towards the demonstration of entanglement between a telecom photon and a long-lived spin wave solid-state quantum memory.
