TL;DR: In this paper, the use of diamond impurity centres as magnetic field sensors is explored, promising a new approach to single-spin detection and magnetic-field imaging at the nanoscale.

TL;DR: Coherent manipulation of an individual electron spin associated with a nitrogen-vacancy center in diamond was used to gain insight into its local environment, which shows that this environment is effectively separated into a set of individual proximal 13Cnuclear spins, which are coupled coherently to the electron spin, and the remainder of the 13C nuclear spins, who cause the loss of coherence.

TL;DR: Using optical and microwave radiation to control an electron spin associated with the nitrogen vacancy color center in diamond, robust initialization of electron and nuclear spin quantum bits (qubits) and transfer of arbitrary quantum states between them at room temperature are demonstrated.

TL;DR: Long-distance entanglement of two electron spin qubits in diamond with a spatial separation of three metres is established using a robust protocol based on creation of spin–photonEntanglement at each location and a subsequent joint measurement of the photons.

TL;DR: In this paper, the 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 is verified using the quantum eraser technique, and demonstrates that a high degree of control over interactions between a solid state qubit and the quantum light field can be achieved.
