Abstract
A quantum information storage device includes a first gas cell, a second gas cell, a light splitter configured to cause first light in a first state to travel along a first optical path intersecting the first gas cell and the first light in a second state to travel along a second optical path intersecting the second gas cell, a second light source configured to emit, to the first gas cell and the second gas cell, second light capable of bringing an atom into a two-photon resonance state with the first light, and a light synthesizer at a subsequent section of the first gas cell and the second gas cell, configured to synthesize third light generated when a photon included in the second light acts on the atom in the two-photon resonance state in the first gas cell and the second gas cell.
