摘要：
We have been studying a superconducting quantum-computing system where superconducting qubits are controlled and read out by rapid single-flux- quantum (RSFQ) circuits In this study, we designed and fabricated an RSFQ microwave chopper. which turns on and oil an externally applied microwave to control qubit states with the time resolution of sub-nanosecond The chopper is implemented in a microwave module and mounted in a dilution refrigerator We tested the microwave chopper at 4 2 K The amplitude of the output microwave was approximately 100 mu V which is much larger than that of previously designed chopper We also confirmed that the irradiation time can be controlled by RSFQ control circuits
