Abstract To provide a quantum interference device that can realize a quantum interference effect having high frequency stability for magnetic field variation.SOLUTION: A quantum interference device 100 comprises: a space 2; and an alkali metal atom cell 3. A static magnetic field having a specific direction and intensity is applied to the space 2. The alkali metal atom cell 3 is provided within the space 2. Alkali metal atoms are filled in the alkali metal atom cell 3. A quantum interference state of the alkali metal atoms is generated by applying the static magnetic field to the alkali metal atom cell 3 and injecting excitation light having at least two different frequency components. A frequency component associated with formation of the quantum interference state, of frequency components of the excitation light is light including linear polarization being the same polarization direction to each other. The static magnetic field applied to the space 2 is adjusted to suppress variation for a magnetic field for a transition frequency between ground levels forming the quantum interference state.SELECTED DRAWING: Figure 21 【課題】磁場変動に対して周波数安定度の高い量子干渉効果を実現することが可能な量子干渉装置を提供する。【解決手段】量子干渉装置100は、空間2と、アルカリ金属原子セル3とを有する。空間2には、特定の方向及び強度の静磁場が印加されている。アルカリ金属原子セル3は、空間2の内部に設けられている。アルカリ金属原子セル3には、アルカリ金属原子が封入されている。アルカリ金属原子セル3に、静磁場が印加され、少なくとも2つの異なる周波数成分を有する励起光が入射されることにより、アルカリ金属原子の量子干渉状態が生じる。励起光の周波数成分のうち、量子干渉状態の形成に関与する周波数成分は、互いに同一の偏光方向である直線偏光を含む光である。空間2に印加された静磁場は、量子干渉状態を形成する基底準位間の遷移周波数についての磁場に対する変動が抑制されるように、調整されている。【選択図】図21
