Abstract
A quantum interference device includes: a gas cell in which metal atoms are sealed; a light emitting unit which emits light to the gas cell; a light receiving unit which receives the light penetrating the gas cell and outputs a light receiving signal; an input unit which inputs the light receiving signal; a light receiving circuit which processes the light receiving signal output from the input unit; a high frequency current generation unit which is arranged with the light emitting unit in a line, and generates high frequency current; and a first output unit which outputs the high frequency current output from the high frequency current generation unit to the light emitting unit, in which the gas cell is disposed between the input unit and the first output unit.
