Impurity-induced dephasing of Andreev states
arXiv:cond-mat/0003344 · doi:10.1103/PhysRevB.63.094505
Abstract
A study is presented concerning the influence of flicker noise in the junction transparency on coherent transport in Andreev states. The amount of dephasing is estimated for a microwave-activated quantum interferometer. Possibilities of experimentally investigating the coupling between a superconducting quantum point contact and its electromagnetic environment are discussed.
