- Abstract
- We have constructed a new type of amplifier whose primary purpose is the readout of superconducting
quantum bits. It is based on the transition of a rf-driven Josephson junction between two
distinct oscillation states near a dynamical bifurcation point. The main advantages of this new amplifier
are speed, high sensitivity, low backaction, and the absence of on-chip dissipation. Pulsed microwave
reflection measurements on nanofabricated Al junctions show that actual devices attain the performance
predicted by theory. (literal)
