Abstract
Embodiments described herein provide systems and methods for acoustically driving spin rotations of diamond nitrogen-vacancy (NV) centers using acoustic transducers. The acoustic transducers may comprise devices such as bulk acoustic resonators or surface acoustic resonators. The systems and methods may allow driving of ms=0 to ms=−1, ms=0 to ms=+1, ms=−1 to ms=0, and ms=+1 to ms=0 single-quantum (SQ) spin transitions without the need to apply magnetic field pulses. This may substantially reduce the size and power requirements of NV center-based sensors. The systems and methods may be used to conduct a variety of measurements, such as measurements of magnetic field, electric field, orientation, strain, or temperature.
Claims20
A system comprising:
- a diamond substrate comprising at least one nitrogen-vacancy (NV) center therein;
- an acoustic transducer mechanically coupled to the diamond substrate;
- and
- a controller coupled to the acoustic transducer and configured to cause the acoustic transducer to generate acoustic waves within the diamond substrate to thereby drive a single-quantum (SQ) transition from a first spin state of the NV center to a second spin state of the NV center.
A method comprising:
- generating acoustic waves within a diamond substrate comprising at least one NV center therein to thereby drive a single-quantum transition from a first spin state of the NV center to a second spin state of the NV center.
