Abstract
A physical field generator generates a magnetic field or an electric field corresponding to an input signal. An optical quantum sensor part generates light corresponding to the magnetic field or the electric field by a sensing member and converts the light into an electrical signal as a sensor signal by a photoelectric element. An analog/digital converter digitizes the sensor signal. Further, the optical quantum sensor part performs a quantum operation with respect to the sensing member mentioned above and causes the sensing member mentioned above to generate the light mentioned above corresponding to the magnetic field or the electric field mentioned above.
