Latest Patents
Christopher Foy holds a patent titled "On-chip detection of spin states in color centers for metrology and information processing." This patent focuses on the Zeeman shift of electronic spins in nitrogen-vacancy (NV) centers in diamond. It has been utilized in lab-scale instruments for ultra-high-resolution, vector-based magnetic sensing. The invention describes a quantum magnetometer in CMOS that incorporates a diamond-nanocrystal layer with NVs or NV-doped bulk diamond on a chip-integrated system. This system provides vector-based magnetic sensing in a compact package. It performs two essential functions for quantum magnetometry: strong generation and efficient delivery of microwave for quantum-state control, and optical filtering/detection of spin-dependent fluorescence for quantum-state readout. The microwave delivery can be achieved with a loop inductor or an array of wires integrated into the chip below the nanodiamond layer or diamond. Additionally, the wire array can suppress excitation light using a combination of plasmonic and, optionally, Talbot effects.
