Superconductor-based integrated circuits are promising for scaling up quantum computer systems by providing high-speed digital signal processing near qubits. We have studied significantly low-power single-flux-quantum (SFQ) circuits employing the lowered critical current density fabrication process for reducing supply currents and also the low-voltage driving technique. In this talk, we report the development of SFQ standard cells for cell-based circuit design.
