Abstract

An n-NV-based gyroscope is provided that includes a diamond structure implanted with a plurality of NV centers, whose nuclear spins form a spin gyroscope. A number of radio-frequency (rf) coils and microwave (μw) co-planar waveguides are fabricated on the diamond structure to provide a sensitive and stable three-axis gyroscope in the solid state while achieving gyroscopic sensitivity by exploiting the coherence time of the ¹⁴N nuclear spin associated with the NV centers in the diamond structure combined with the efficient optical polarization and measurement of electronic spin.

Claims

1. An n-NV-based gyroscope comprising:

a diamond structure implanted with a plurality of NV centers, whose nuclear spins form a spin gyroscope; and

a plurality of radio-frequency (rf) coils and microwave (μ

w) co-planar waveguides being fabricated on the diamond structure to provide a sensitive and stable three-axis gyroscope in the solid state while achieving gyroscopic sensitivity by exploiting the coherence time of the nuclear spin associated with the NV centers in the diamond structure combined with the efficient optical polarization and measurement of electronic spin.
