A robust scheme for quantum information processing in cavity QED
Shi‐Biao Zheng · Journal of Physics B Atomic Molecular and Optical Physics · 2006
We propose a robust scheme for the implementation of two-qubit phase gates with a cavity QED system. After the gate operation the computational basis states are equally damped by the decoherence effect and thus the gate error is suppressed. The scheme is based on resonant atom–cavity interaction and thus the operation speed is high. During the atom–cavity interaction no external laser fields are required and thus the gate errors arising from external sources are suppressed.
