Abstract

Fast, single-photon detection enables the observation of entanglement between a stationary quantum bit (a single quantum dot spin) and a propagating quantum bit (a single photon), marking a first step towards the implementation of a quantum network with nodes consisting of semiconductor spin quantum bits.
