Decoherence in a Cooper pair shuttle
arXiv:cond-mat/0212414 · doi:10.1103/PhysRevB.68.140502
Abstract
We examine decoherence effects in the Josephson current of a Cooper pair shuttle. Dephasing due to gate voltage fluctuations can either suppress or enhance the critical current and also change its sign. The current noise spectrum displays a peak at the Josephson coupling energy and shows a phase dependence.
