Future generations of quantum computers are expected to operate in a paradigm where multi-qubit devices will predominantly perform circuits support error correction. Highly integrated cryogenic electronics key enabling technology the control large numbers physical qubits that be required this fault-tolerant, error-corrected regime. Here, we describe our perspectives on cryoelectronics-driven qubit architectures, and then an implementation scalable, low-power, state controller includes domain-specific processor SSB upconversion I/Q-mixer-based RF AWG. We also FPGA-based emulation platform is able closely reproduce system intention, which was used verify different aspects ASIC design situ transmon experiments.
