Keywords:superconductor, quantum bit, single flux quantum circuit

We have designed single-flux-quantum circuits with a critical current density process lowered to 250 A/cm2 toward quantum bit control in dilution refrigerators. We will report expected operating frequency, estimated power consumption, and obtained results from the fabricated devices.
