Abstract

We give a simple way to realize the C-NOT gate through conditional geometric phase shift with NMR. Comparing with the previous work(Jones et al Nature {\bf 403}, 869(2000)), our scheme has two advantages. We use the non-adiabatic operation, thus the detection is less affected by the decoherence. Also, we take the time evolution on zero dynamic phase loop, we need not take any extra operation to cancel the dynamic phase.
