TL;DR: It is demonstrated coherent control of a quantum two-level system based on two-electron spin states in a double quantum dot, allowing state preparation, coherent manipulation, and projective readout based on rapid electrical control of the exchange interaction.

TL;DR: An approach to nanoscale magnetic sensing is experimentally demonstrated, using coherent manipulation of an individual electronic spin qubit associated with a nitrogen-vacancy impurity in diamond at room temperature to achieve detection of 3 nT magnetic fields at kilohertz frequencies after 100 s of averaging.

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: In this article, a scanning single-electron transistor is used to map the local density of states and the carrier density landscape in the vicinity of the neutrality point, and it is shown that electron-hole puddles can be quantitatively accounted for by considering noninteracting electrons and holes.

TL;DR: A robust method for scanning a single nitrogen-vacancy centre within tens of nanometres from a sample surface that addresses both of these concerns is demonstrated, and is able to image magnetic domains with widths of 25 nm, and demonstrate a magnetic field sensitivity of 56 nT Hz(-1/2) at a frequency of 33 kHz, which is unprecedented for scanning nitrogen-Vacancy centres.
