A quantum interference device includes: an atomic cell in which alkali metal is sealed; a light source that emits light that excites the alkali metal; a light source temperature adjuster that adjusts temperature of the light source; a light receiver that receives light transmitted through the atomic cell and outputs an output signal in accordance with a light reception intensity; a detector that outputs an output signal in accordance with a chronological change in an amount of the light transmitted through the atomic cell based on the output signal of the light receiver; and a light source temperature controller that controls driving of the light source temperature adjuster based on the output signal of the detector.
