Abstract: Entanglement of two electron spin qubits in diamond with a spatial separation of three metres is reported; such entanglement can be combined with recently achieved initialization, readout and entanglement operations on local long-lived nuclear spin registers, and paves the way for deterministic long-distance teleportation, quantum repeaters and extended quantum networks.
