Title: Software and Architecture for Reliable Quantum Computing
Abstract:
Quantum computers promise computational advantages for many important applications, but noisy quantum devices lead to computational errors which limit us from running these applications with high fidelity. Quantum information can be protected by using Quantum Error Correction (QEC) codes but requires huge redundancy which may be impractical on Noisy Intermediate Scale Quantum (NISQ) systems with few hundreds of qubits. Instead, NISQ systems execute programs in the presence of noise and are simultaneously used to study QEC so that large-scale fault-tolerant quantum computers can be built in future.
In this talk, I will discuss some of my recent works on software techniques to mitigate errors in NISQ systems and describe some architecture solutions for fault-tolerant quantum systems. First, I will discuss JigSaw, a software framework that reduces the impact of measurement errors by running additional copies of a program where each copy measures only a subset of qubits and uses the partial information from the subset measurements to improve the quality of solutions. Second, I will describe LILLIPUT, a lightweight reconfigurable practical lookup table decoder, a logic that identifies errors in real-time, for small QEC codes. Finally, I will describe the AFS decoder that focuses on the system level architecture and organization of decoders in large fault-tolerant systems.
