TL;DR: This work shows how magneto-optical spin detection can be used to determine the location of a spin associated with a single nitrogen-vacancy centre in diamond with nanometre resolution under ambient conditions, and demonstrates the use of a single diamond spin as a scanning probe magnetometer to map nanoscale magnetic field variations.

TL;DR: Here, it is demonstrated the synthesis and application of ultrapure isotopically controlled single-crystal chemical vapour deposition (CVD) diamond with a remarkably low concentration of paramagnetic impurities, and single electron spins show the longest room-temperature spin dephasing times ever observed in solid-state systems.

TL;DR: In this paper, point defects in diamond known as nitrogen-vacancy centres have been shown to be sensitive to minute magnetic fields, even at room temperature, and a demonstration that the spin associated with these defect centres is also sensitive to electric fields holds out the prospect of a sensor that can resolve single spins and single elementary charges at the nanoscale.

TL;DR: In this article, coherent coupling between two electron spins separated by almost 10 nm has been demonstrated, which might enable the construction of a network of connected quantum registers at room temperature, at this distance, the spins can be addressed individually.

TL;DR: A versatile method to polarize single nuclear spins in diamond, based on optical pumping of a single nitrogen-vacancy (NV) defect and mediated by a level anticrossing in its excited state is reported.
