Abstract
We develop a scheme for probabilistic controlled sign (CS) gate that is performed via modified GHZ mode entangled state. Success probability of the CS gate is 1/4. We show fidelity of the CS gate based on the GHZ quantum channel is higher then one of the same operation based on two-photon quantum channel.
