Quantum Reliability: Circuit Susceptibility, Faults, and Integration Issues

Summary:
Quantum computing is ushering in a transformative era in computation. The fundamental building blocks, qubits, exploit quantum physics to amplify computational parallelism and speed. Yet, these devices grapple with intrinsic noise and external factors like ionizing radiation, necessitating inventive strategies for enhanced reliability. Our presentation delves into vulnerabilities in current quantum technologies, exploring intrinsic noise with predictable effects and radiation-induced transient faults with unpredictable alterations to qubits. A focal point is the introduction of QuFI, the Quantum Fault Injector—an open-source tool designed to inject noise into quantum circuits for monitoring its propagation to the circuit output. QuFI serves as a valuable resource for scrutinizing the susceptibility of both qubits and circuits, identifying critical areas and primary sources of output corruption. As a case study, we showcase the application of QuFI to superconducting qubits, offering real-world insights into its efficacy. Additionally, we extend our exploration to the integration challenges of quantum computing with high-performance computing infrastructures. Our aim is to provide a comprehensive understanding of the prevailing reliability challenges in quantum computing, fostering further research and innovative solutions in this evolving field.
