A survey of modern cryogenic electronics patents is the focus of this article. Modern patent databases such as PatSearch, Espacenet, and Orbit Questel were used to conduct an information search. Patent families related to cryogenic electronics over the past 20 years have been identified. The dynamics of patenting in this area is shown. The world leaders in the number of patents are revealed. The largest number of patents is registered in China. IBM holds the most patents in this field worldwide. Cryogenic electronics are the most dynamically developing industry. Modern commercially attractive solutions are associated with the development of a quantum computer. The development of wireless systems of qubit control and reading is the most relevant. It was found that there is no available information about the possibility of using an industrially produced electronic component base to create cryogenic electronics devices. Electronic components specially designed for cryogenic conditions are most often used, as a rule, using the superconductivity effect.

Quantum computing is developing rapidly, especially those systems based on superconductors, electron or hole spin in semiconductors[1], which generally operate at sub-1 K temperatures[2]. And the classical electronics control system for qubits at room temperature meets increasing challenges, due to utter interconnect complexity, poor system reliability, and cost. Integrating part or all of the interface electronics inside the dilution refrigerator becomes an promising branch. For the convenience of cryo-electronics testing and establishing of the whole electronics control system for quantum computing at cryogenic temperatures, we describe the operation of some commercial devices at cryogenic temperatures, including two FPGAs respectively on 28 nm and 16 nm process node and three GaAs RF switches.

Cryogenic CMOS control and readout electronics for quantum computing using superconducting qubits offers several potential advantages versus the use of room temperature electronics, including reduced wiring and lower cost per control channel. The development and practical implementation of such electronics at a mass-production scale for systems with tens of thousands of channels, however, requires circuit characterization in the target cryogenic use environment and with interfaces as close as possible to those that will be used in a real quantum machine. The cryogenic use environment and interfaces for test are usually far from the almost ideal conditions that can be achieved in a regular cryogenic probe station. In this paper, we describe a new testbed for the characterization of CMOS circuits at cryogenic temperatures that solves some of these problems.
