Abstract
A study is presented concerning the influence of flicker noise in the junct ion transparency on coherent transport in Andreev states. The amount of dep hasing is estimated for a microwave-activated quantum interferometer. Possi bilities of experimentally investigating the coupling between a superconduc ting quantum point contact and its electromagnetic environment are discusse d.
