A tipping pulse scheme for an rf-SQUID qubit

Abstract

We present a technique of using a stream of single flux quantum (SFQ) pulses magnetically coupled to the qubit junction to control the state of a rf-SQUID qubit. This momentarily suppresses the critical current of the junction and lowers the potential barrier so the tunneling oscillation frequency is increased.
