dc.descriptionWe consider an atom-field coupled system, in which two pairs of four-level atoms are respectively driven by laser fields and trapped in two distant cavities that are connected by an optical fiber. First, we show that an effective squeezing reservoir can be engineered under appropriate conditions. Then, we show that a two-qubit geometric CPHASE gate between the atoms in the two cavities can be implemented through adiabatically manipulating the engineered reservoir along a closed loop. This scheme that combines engineering environment with decoherence-free space and geometric phase quantum computation together has the remarkable feature: a CPHASE gate with arbitrary phase shift is implemented by simply changing the strength and relative phase of the driving fields.
dc.description4 pages, 2 figures; v2, We have maken considerable changes. New model to engineer effective reservoir without broadband squeezing light is proposed, which makes the scheme more practical. Main results are not changed; v3, accepted for PRA. Change style to PRA
