Technology Introduction:
Our cryo-CMOS qubit controller consists of a digital control circuit, an I/Q numerically controlled oscillator, a high-speed digital-to-analog converter, an 18-GHz mixer, and a balun. The architecture provides programmable control of the output signal for manipulating qubit states. This technology plays a pivotal role in replacing room-temperature electronics for a large-scale quantum computer.
Industry Applicability:
Cryo-CMOS enables scalable, energy-efficient quantum control at cryogenic temperatures, reducing wiring, signal loss, and costs. It technically, economically accelerates the commercialization of quantum computers and also has applications in sensors and communication. With Taiwan’s semiconductor industries, this technique can be one of the driving forces behind Taiwan quantum computing technology.
