Josephson nanocircuit in the presence of linear quantum noise
arXiv:cond-mat/0301363 · doi:10.1016/S1386-9477(02)00948-7
Abstract
We derive the effective hamiltonian for a charge-Josephson qubit in a circuit with no use of phenomenological arguments, showing how energy renormalizations induced by the environment appear with no need of phenomenological counterterms. This analysis may be important for multiqubit systems and geometric quantum computation.
