Magnetic sensing and imaging using interactions between surface electron spins and solid state spins

摘要

Systems and methods for magnetic sensing and imaging include a sensor having a network of isolated electron-spin quantum bits (qubits) disposed on the surface of the sensor; and a solid state electronic spin system disposed below the surface of the sensor, wherein the solid state electronic spin system has a spin-state dependent fluorescence; a source of light; a source of first external perturbation, wherein the source of first external perturbation generates a magnetic field; a source of second external perturbation; wherein, the source of light and the first and second external perturbations are configured to coherently and independently manipulate the spin states of at least one qubit and at least one solid state electronic spin system; and a detector to optically measure the solid-state electronic spins spin-state dependent fluorescence.
