Today the qubits are mostly controlled by conventional electronics wor king at room temperature. This thermal gap can be readily bridged by a few wires since today’s quantum computers employ only a few qubits. However \, practical quantum computers will require more than thousands of qubits\ , making this approach impractical. A more scalable approach requires oper ating a complex electronic interface at cryogenic temperature\, very close to the quantum processor\, eventually in the same package or even on the same chip. Thanks to its high integration capabilities\, CMOS is the most viable technology for such a cryogenic interface. In this talk\, we will f irst review the functionalities required to drive and control the most pop ular qubit technologies\, and the requirements on the performance of the e lectronics. Based on those requirements and the behavior of CMOS devices a t cryogenic temperature\, several state-of-the-art cryo-CMOS circuits and systems have been designed\, both for qubit drive and readout\, and we wil l show their verification with real-world qubits\, highlighting challenges and opportunities. Finally\, the prospects towards large-scale quantum co mputers will be outlined\, and we will try to answer the questions: Is the electronics a bottleneck for future quantum computers? How will we design cryo-CMOS circuits to tackle this challenge?\n\nFabio Sebastiano received the B.Sc. (cum laude) and M.Sc.
