Investigating Interface Disorder in Cryogenic CMOS Through Noise Spectroscopy

Quantum computers have the potential to solve problems that are beyond the capabilities of classical computers, such as prime number factorization. Systems with millions of logical qubits could revolutionize fields like cryptography, artificial intelligence, and physics simulations. However, scaling these systems presents a major challenge. Typically, qubits operate at millikelvin temperatures, while the control electronics remain outside the cryostat at room temperature, connected by long wires. This configuration adds complexity and makes wiring a significant bottleneck in the development of large-scale quantum computers. Cryogenic CMOS technology offers a promising solution by allowing control electronics to be integrated inside the cryostat, near the qubits, at temperatures around 4 K. Nevertheless, the performance of CMOS devices at cryogenic temperatures is limited by interface disorder, which generates excess noise and reduces the quantum processor's efficiency. This project will focus on using noise analysis to investigate the impact of interface disorder on scaled CMOS technology nodes. You will gain hands‑on experience with cutting‑edge technology and have access to world‑class laboratories, contributing directly to a better understanding future quantum computing control hardware.
