R. G. Herb Condensed Matter Seminar
CNOT quantum logic with weakly coupled cubits
Time: 10:00 am
Place: 5310 Chamberlin
Speaker: Mike Geller, Dept. of Physics and Astronomy, University of Georgia
Abstract: Effective protocols for performing CNOT quantum logic with qubit devices coupled by particular high-symmetry (Ising or Heisenberg) interactions are well established. However, many architectures being considered for practical quantum computation involve qubits or qubits and resonators coupled by more complicated and less symmetric interactions. Here we investigate the general problem of weakly but otherwise arbitrarily coupled two-level systems, and present a simple and generally applicable CNOT gate construction. The design will be especially effective when applied to architectures with fast and accurate single-qubit control.
