| titleOfInvention | A quantum-enhanced magnetic field gradiometer and magnetometer |
| abstract | The invention discloses a quantum-enhanced magnetic field gradiometer. The magnetic field gradiometer uses a coherent light source such as a titanium sapphire laser or a semiconductor laser as an initial incident light source, and uses a twin beam detection method to combine the quantum magnetometer and the magnetic field gradiometer. The advantages are organically combined, and the shot noise and common-mode magnetic field noise of light are reduced at the same time, including the first coherent light source, the second coherent light source, the third coherent light source, the seed light, the rubidium-85 atomic ensemble, the idler light, the signal Light, light shield, first rubidium-87 atomic ensemble, second rubidium-87 atomic ensemble, first polarizing beam splitter, second polarizing beam splitter, first acousto-optic modulator, second acousto-optic modulator , The first photodetector, the second photodetector, the first 1/2 wave plate, the second 1/2 wave plate, the first 1/4 wave plate, the first 1/4 wave plate, the subtractor. The invention also discloses a magnetometer comprising the above quantum-enhanced magnetic field gradiometer. |
