A high-frequency magnetic field generatorapplies microwave to a magnetic resonance membercapable of an electron spin quantum operation using the microwave. A magnetapplies a static magnetic field to the magnetic resonance member. An irradiating deviceirradiates the magnetic resonance memberwith light of a specific wavelength. A flux transformersenses a measurement target magnetic field using a primary coiland applies an application magnetic field corresponding to the sensed measurement target magnetic field to the magnetic resonance memberusing a secondary coil. Further, the magnetic resonance memberis arranged at a position in a hollow part of the secondary coilof the flux transformerand in a hollow part of the magnet

Magnetic field measurement apparatus and magnetic field measurement method

A magnetic resonance memberincludes a crystal structure and is capable of electron spin quantum operations with microwaves of different frequencies corresponding to arrangement orientations of a vacancy and an impurity in a crystal lattice. A magnetic field transmission unitsenses a measurement target magnetic field at plural measurement positions different from each other, and applies application magnetic fields corresponding to the measurement target magnetic field sensed at the plural measurement positions to the magnetic resonance memberalong respective different directions corresponding to the aforementioned arrangement orientations. A measurement control unitcontrols a high frequency power supply, and determines detection values detected by a detecting device (an irradiating deviceand a light receiving device) of the physical phenomena corresponding to the plural measurement positions. A calculation unitcalculates the measurement target magnetic field at the plural measurement positions on the basis of the detection values.
