Methods, systems, and apparatus for storage, transfer and/or control of information via matter wave dynamics

A method of transferring optical information between first and second spatially separated atomically identical Bose-Einstein condensates, the method comprising:

• A) irradiating the first Bose-Einstein condensate with an optical beam resonant or near-resonant with a first transition between a second energy state and a third energy state of bosons of the first Bose-Einstein condensate;
• B) irradiating the first Bose-Einstein condensate with a first optical pulse resonant or near-resonant with a second transition between a first energy state and the third energy state of the bosons of the first Bose-Einstein condensate, the first optical pulse propagating counter to a propagation direction of the optical beam, wherein the transferred optical information relates at least in part to a phase and/or amplitude of the first optical pulse;
• C) extinguishing the optical beam at a storage time at which the first optical pulse is contained completely within the first Bose-Einstein condensate, so as to eject from the first Bose-Einstein condensate a coherent matter wave pulse carrying the optical information from the first optical pulse;
• D) injecting the second Bose-Einstein condensate with the coherent matter wave pulse;
• and
• E) irradiating the second Bose-Einstein condensate with the optical beam at a revival time at which the coherent matter wave pulse is embedded in the second Bose-Einstein condensate so as to generate a second optical pulse from the second Bose-Einstein condensate based on the optical information carried by the coherent matter wave pulse.
