Cryogenic CMOS

Research area · SDU Microelectronics

Quantum computing harnesses the unique properties of the quantum world to achieve information processing beyond classical limits, yet scaling to thousands of qubits remains a major challenge due to coherence loss, interconnect complexity, and the need for precise control at cryogenic temperatures.

Research focus

A promising solution is to use CMOS chips, containing billions of transistors, as the foundation for scalable quantum systems, with cryo-CMOS controllers operating near the quantum processor at cryogenic temperatures.

Cryo-CMOS circuits

We develop and model cryo-CMOS circuits that function reliably from 30 mK to 77 K.
