摘要：
A scheme is proposed to implement a two-qubit conditional quantum phase gate for the intracavity field using a single ladder-type three-level atom driven by two modes in a high-Q cavity. The quantum information is encoded on the Fock states of a bimodal cavity. The averaged fidelity of the gate can be expected to reach 99.86%.
