| Outline of Final Research Achievements |
A single electron spin associated with a nitrogen-vacancy pair defect in diamond is used as a quantum sensor to realize a mission impossible by the classical means; measurement of the extremely small magnetic field arising from a single nuclear spin followed by quantum manipulation of the same nuclear spin (single nuclear spin magnetic resonance) to determine the exact position of the nuclear spin in the three-dimensional-space with the atomic-level (angstrom) spatial resolution. This level of atomic-scale magnetic resonance imaging (MRI) was performed at room temperature for the first time. In the course of reaching this goal, high quality NV sensor fabrication methods and a variety of a single electron and nuclear spin quantum manipulation protocols leading to quantum sensing was developed. In the area of biosensing, a temperature measurement within cells was demonstrated successfully while the original goal of sensing electric and magnetic field within cells was not achieved.
