High fidelity state mapping performed in a V-type level structure via stimulated Raman transition
arXiv:1401.0057 · doi:10.1088/0953-4075/48/5/055502
Abstract
It is proved that a qubit encoded in excited states of a V-type quantum system cannot be perfectly transferred to the state of the cavity field mode using a single rectangular laser pulse. This obstacle can be overcome by using a two-stage protocol, in which the fidelity of a state-mapping operation can be increased to nearly one.
