Cryogenic CMOS and Quantum Computing


Energy dissipation has become the most critical challenge for today’s IC industry. High-speed and energy-efficient data centers are highly demanded in today’s Big Data era. When operating at cryogenic temperatures, the performance of transistors gets greatly boosted in terms of both speed (due to lower delay and turn-on characteristics) and power (due to suppressed leakage and smaller SS). In addition, low-temperature also opens new opportunities for superconductor/quantum computers and high-performance computing.
