Abstract |
|
|
| We propose a scheme to direct implementation the four-qubit phase gate by passing a five-level atom (which is initially in
the lower state) across a multi-mode cavity QED. The four qubit are represented by the photons in the four modes of the cavity field. In
particular, the four-qubit quantum phase gate can be implemented if certain conditions for transition strength, detuning and interaction
time are better satisfied. Subsequently we will discus this phase gate scheme. |
