摘要：

The heating effect-i.e., photon fluctuation-occurs in the geometric logic gating in cavity QED due to a noisy environment. We propose an efficient scheme to suppress this heating by combining the displacementlike operator method [Phys. Rev. A 73, 032344 (2006)] with the method of double-Hamiltonian evolution [Phys. Rev. Lett. 90, 217901 (2003)]. Discussions about the fidelity and the success probability of the proposed scheme as well as the experimental feasibility are made in detail.
