Abstract:A method for storing quantum information is presented for 3-level atomic systems interacting dipolarly with a single radiation field. The method involves performing simple local SU(2) rotations on the Hamiltonian. Under equal detuning, these transformations decouple one of the atomic levels from the electromagnetic field for the Λ- and V -configurations, yielding two effective 2-level systems (qubits) plus an isolated atomic level; this allows for the exchange of information between the qubits. This rotation prese… Show more
