Abstract

Solid entanglement Quantum entanglement is widely used for fundamental tests of quantum mechanics and applications such as quantum cryptography. Previous experiments have demonstrated entanglement of optical photons with trapped atoms or ions and atomic ensembles. Here the authors realize quantum entanglement between the polarization of a single optical photon and a solid-state qubit associated with the single electronic spin of a nitrogen vacancy centre in diamond. This may provide a key building block for the solid-state realization of quantum optical networks.
