Toward quantum teleportation on demand

Quantum information processing relies on the ability to store, manipulate, and propagate information encoded in quantum states of matter. Doing so, however, may destroy or compromise these delicate quantum states. Pfaff et al. present a quantum teleportation protocol that uses two defects in diamond 3 m apart (see the Perspective by Atatüre and Morton). They then map the quantum state of one of the diamond defects onto the other. The work presents a key building block for the successful development of larger quantum networks.
