We analyse decoherence in Josephson qubits induced by background charges responsible for 1/f noise. To this end we introduce a quantum mechanical model of a discrete environment. The discrete nature of the environment leads to a number of new features which are mostly pronounced for slowly moving charges.

Abstract
We analyse decoherence in Josephson qubits induced by background charges responsible for 1/f noise. To this end we introduce a quantum mechanical model of a discrete environment. The discrete nature of the environment leads to a number of new features which are mostly pronounced for slowly moving charges.File in questo prodotto:
