TL;DR: This work experimentally demonstrates a novel nanoscale temperature sensing technique based on optically detected electron spin resonance in single atomic defects in diamonds, which should allow the measurement of the heat produced by chemical interactions involving a few or single molecules even in heterogeneous environments like cells.

TL;DR: In this article, the authors demonstrate entanglement between two engineered single solid-state spin quantum bits (qubits) at ambient conditions and show that ground-state quantum correlations can be detected by quantum state tomography.

TL;DR: In this paper, a novel nanoscale temperature sensing technique based on optically detected electron spin resonance in single atomic defects in diamonds has been proposed to measure the heat produced by chemical interactions involving a few or single molecules.

TL;DR: Optimal control of a prototype spin qubit system consisting of two proximal nitrogen-vacancy centres in diamond is experimentally demonstrated, and nuclear spin entanglement over a length scale of 25 nm is demonstrated.

TL;DR: In this article, a microwave plasma-assisted chemical vapor deposition diamond growth technique on (111)-oriented substrates, which yields perfect alignment (94% ± 2%) of as-grown NV centers along a single crystallographic direction.
