CryoCMOS ASICs for controlling transmon qubits

CryoCMOS control electronics have the potential to reduce system costs, minimize complexity and improve performance of quantum gates. Historically, commercially available control electronics have been used to support quantum processor research and development; however, these electronics tend to be general purpose, power hungry and over-engineered for fault tolerant operation of a specific quantum processor architecture. Application specific integrated circuits (ASICs) that are designed uniquely to a quantum processor are a better suited to satisfy performance requirements and scaling demands of fault tolerant quantum computation of a specific QPU implementation. In this presentation we discuss a cryoCMOS ASIC designed for controlling transmon qubits, along with qubit measurements including noise characterization as measured by dephasing and two-qubit randomized benchmarking.
