Cryogenic CMOS Circuits for Quantum Computing Control Electronics

Quick fact

Some cryogenic CMOS circuits operate at 4 kelvin (about -269°C) and consume microwatts per qubit, drastically reducing the number of cables entering the fridge.

Why this is interesting

Quantum computers need to be kept colder than outer space, yet their control electronics are usually warm and far away. How can we shrink the gap and still control a million qubits?
