Latest Patents

One of Fahey's most significant patents is the Polariton-stabilized solid-state spin clock. This invention utilizes an ensemble of spin defect centers or other atom-like quantum systems in a solid-state host. It serves as a compact alternative for an atomic clock by overcoming magnetic and temperature-induced systematics. The architecture hybridizes a microwave resonator with a magnetic-field-insensitive spin transition within the ground state of a spin defect center, such as a nitrogen vacancy center in diamond. Detailed numerical and analytical modeling indicates a potential fractional frequency instability below 10 over a 1-second measurement time, assuming present-day experimental parameters. This stability represents a significant improvement over the state-of-the-art in miniaturized atomic vapor clocks.
