| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Generally, superconducting qubits are controlled by an irradiation of a microwave pulse. We proposed a microwave pulse generator based on pulse density modulation for controlling qubits using single flux quantum (SFQ) circuits. The proposed microwave pulse generator is composed of a circular shift register (CSR) and a band-pass filter (BPF). In this study, we investigated a relationship between the target envelope of the microwave amplitude and the SFQ pulse density based on the transfer function of the BPF. | |
