| Abstract(in English) | Qubits with Josephson Junctions are controlled by microwave pulses of suitable duration time and amplitude. Control of each qubit is performed by external microwave pulses so far, but it is challenging for realizing large-scale quantum computing because of wiring problem and power consumption problem. In this study, we designed a microwave switch using rapid single-flux-quantum (RSFQ) logic, which generates microwave pulses of various amplitude and time width. In simulations, we confirmed that it could generate microwave pulses of 5 GHz whose amplitude is ranging 0.30-3.0 ?A. And it has adequate characteristics for quantum gate control. |
