摘要：

We present a theoretical proposal for a microwave-driven circuit composed of superconducting resonators and qubits, which shows a bistable behavior, and we present a simple mechanism that allows single-or few-photon microwave pulses to work as set and reset signals that switch the circuit between its stable modes. The resulting system constitutes an ultralow-energy set-reset flip-flop device, and we show that its memory lifetime far exceeds the lifetime of states stored in any of its separate components.
