Claim 0:
1. A magnetic field measurement apparatus, comprising:
a magnetic resonance member that includes a crystal structure and 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 high-frequency magnetic field generator that applies a magnetic field as a microwave to the magnetic resonance member;
a high frequency power supply that causes the high-frequency magnetic field generator to conduct a current for the microwave;
a magnetic field transmission unit that senses 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 member along respective different directions corresponding to the arrangement orientations;
a detecting device that detects physical phenomena corresponding to the application magnetic fields using the magnetic resonance member;
a measurement control unit that controls the high frequency power supply, and determines detection values detected by the detecting device of the physical phenomena corresponding to the plural measurement positions; and
a calculation unit that calculates the measurement target magnetic field at the plural measurement positions on the basis of the detection values.
