摘要： The magnetic resonance member 1 is a member that is arranged in a measurement target AC physical field, and in which a quantum operation can be performed in a specific quantum system. The coil 2 and the high frequency power supply 3 apply a magnetic field of a microwave to the magnetic resonance member 1. The irradiating device 4 irradiates the magnetic resonance member 1 with light, and the detecting device 5 detects from the magnetic resonance member 1 a physical phenomenon corresponding to the measurement target AC physical field. Further, the measurement control unit 21 performs the DC physical field measurement sequence a predetermined plural times, and in each of the plural times of the DC physical field measurement sequence, determines a detection value of the physical phenomenon detected by the detecting device 5. The calculation unit 22 calculates a measurement result for a specific time span of the measurement target AC physical field on the basis of the detection values corresponding to the plural times of the DC physical field measurement sequence.

摘要： An ODMR member is arranged in a measurement target AC magnetic field. A coil applies a magnetic field of a microwave to the ODMR member. A high frequency power supply causes the coil to conduct a current of the microwave. An irradiating device irradiates the ODMR member with light. A light receiving device detects light that the ODMR member emits. A measurement control unit performs a predetermined DC magnetic field measurement sequence at a predetermined phase of the measurement target AC magnetic field, and in the DC magnetic field measurement sequence, controls the high frequency power supply and the irradiating device and thereby determines a detection light intensity of the light detected by the light receiving device. A magnetic field calculation unit calculates an intensity of the measurement target AC magnetic field on the basis of the predetermined phase and the detection light intensity.

摘要： A substrate 1 includes a color center excited by excitation light, and at least a pair of reflection members 21a, 21b are arranged with gaps from the substrate 1. The substrate 1 causes the excitation light entering the substrate 1 to exit through its surfaces without reflection, and the reflection members 21a, 21b cause the exited excitation light to reflect at the reflection surface 21-1 or 21-2 and enter the substrate 1, and cause the excitation light to repeatedly enter and exit the substrate 1 and thereby pass through the substrate 1 only a predetermined number of times. Here, the irradiating device 4 emits the excitation light such that the excitation light is incident to the reflection surface 21-1 or 21-2 with an angle perpendicular to one axis among two axes of the reflection surface 21-1 or 21-2 and with a predetermined slant angle from the other axis.

摘要： A magnetic resonance member 1 includes 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 unit 4 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 1 along respective different directions corresponding to the aforementioned arrangement orientations. A measurement control unit 21 controls a high frequency power supply 12, and determines detection values detected by a detecting device (an irradiating device 5 and a light receiving device 6) of the physical phenomena corresponding to the plural measurement positions. A calculation unit 22 calculates the measurement target magnetic field at the plural measurement positions on the basis of the detection values.
