Relaxation and Dephasing in a Flux-qubit
P. Bertet, I. Chiorescu, G. Burkard +4
We report detailed measurements of the relaxation and dephasing time in a flux-qubit measured by a switching DC SQUID. We studied their dependence on the two important circuit bias…
Theory of solid state quantum information processing
Guido Burkard
Recent theoretical work on solid-state proposals for the implementation of quantum computation and quantum information processing is reviewed. The differences and similarities betw…
Circuit theory for decoherence in superconducting charge qubits
Guido Burkard
Based on a network graph analysis of the underlying circuit, a quantum theory of arbitrary superconducting charge qubits is derived. Describing the dissipative elements of the circ…
Non-additivity of decoherence rates in superconducting qubits
Guido Burkard, Frederico Brito
We show that the relaxation and decoherence rates 1/T_1 and 1/T_2 of a qubit coupled to several noise sources are in general not additive, i.e., that the total rates are not the su…
Asymmetry and decoherence in a double-layer persistent-current qubit
Guido Burkard, David P. DiVincenzo, P. Bertet +2
Superconducting circuits fabricated using the widely used shadow evaporation technique can contain unintended junctions which change their quantum dynamics. We discuss a supercondu…
Fault-Tolerant Quantum Computation For Local Non-Markovian Noise
Barbara M. Terhal, Guido Burkard
We derive a threshold result for fault-tolerant quantum computation for local non-Markovian noise models. The role of error amplitude in our analysis is played by the product of th…
