Abstract :
A necessary part of a quantum repeater is an on-demand quantum memory. In this paper we report on recent progress of achieving such a memory in a solid-state system. We show storage of a few photon optical pulse as a spin-wave in a crystal, preserving the states´ coherence. We show how it is possible to extend the storage time and increase the process efficiency.
