Scheme for Preparation of W State Among Three Cavity Modes
Zhiming Zhan, Jiahua Li, Wen‐Xing Yang · Communications in Theoretical Physics · 2005
We present a scheme of preparing the tripartite W state among three cavity modes of radiation field inside high-Q superconducting cavities. Our scheme is based on the interaction of a four-level atom with the cavity field for precalculated interaction times with every mode.
