摘要: We propose a scheme to implement the Deutsch--Jozsa algorithm by using Schr\"{o}dinger cat states in cavity quantum electron-dynamics (QED). The scheme is based on the Raman interaction of a degenerate three-level \Lambda -type atom with a coherent state in a cavity. By using Schr\"{o}dinger cat states, the atomic spontaneous emission can be minimized and the Hadamard transformation in our scheme is not needed.
