Abstract:
A quantum interference device includes an atomic cell which has an internal space enclosing an alkali metal, a first light source which emits a resonance light pair circularly polarized in the same direction as each other and exciting the alkali metal, a second light source which emits an adjustment light, and a light receiver, wherein the atomic cell includes a first layer which is provided on an inner wall surface surrounding the internal space of the atomic cell and contains a compound derived from a first compound that is an oxide of a metal having a lower ionization tendency than the alkali metal, a second layer which is provided on the first layer and contains a compound derived from a second compound having a functional group that undergoes an elimination reaction with the compound derived from the first compound, and a third layer which is provided on the second layer and contains a compound derived from a third compound that is nonpolar.

Claim (Index 1):
A quantum interference device, comprising:\n an atomic cell which has an internal space enclosing an alkali metal; a first light source which emits a resonance light pair that is circularly polarized in the same direction as each other and excites the alkali metal; a second light source which emits an adjustment light that is circularly polarized in an opposite direction to that of the resonance light pair and excites the alkali metal; and a light receiver which receives the resonance light pair passing through the internal space, wherein the atomic cell includes\n a first layer which is provided on an inner wall surface surrounding the internal space of the atomic cell and contains a compound derived from a first compound that is an oxide of a metal having a lower ionization tendency than the alkali metal, \n a second layer which is provided on the first layer and contains a compound derived from a second compound having a functional group that undergoes an elimination reaction with the compound derived from the first compound, and a third layer which is provided on the second layer and contains a compound derived from a third compound that is nonpolar.
