Microwave bifurcation of a Josephson junction: Embedding-circuit requirements
Microwave bifurcation of a Josephson junction: Embedding-circuit requirements
A Josephson tunnel junction which is rf driven near a dynamical bifurcation point can amplify quantum signals. However, the bifurcation point will exist robustly only if the electrodynamic environment of the junction meets certain criteria. We develop a general formalism for dealing with the nonlinear dynamics of a Josephson junction …
