CMOS Cryo-Electronics for Quantum Computing
2020
To scale up quantum computers to large number of qubits, there is a need to bring the classical interface electronics closer to the qubits operating at milli-Kelvin temperature. This has sparked a recent revival in cryo electronics research. This paper presents a short overview of recent state of the art, shows how nanoscale CMOS transistor properties are conveniently well suited for this task when properly modeled, and discusses a 4K superconducting dispersive readout circuit and a mK RF multiplexer as two examples.
