Architectures and Applications for Scalable Quantum Information Systems

摘要

The goal of this project was to understand what key interchangeable elements form a scalable, fault-tolerant quantum information systems architecture. The effort was a collaboration between computer science and physical sciences involving four groups: MIT, providing experimental quantum technology parameters and fundamental expertise in quantum information theory; UC Davis, devising fault-tolerant architecture designs and implementing numerical simulations; UC Berkeley, creating quantum cryptosystems and providing distributed applications; and U Washington, focusing on languages for quantum computation and an architectural simulator. Accomplishments of project include: design of several complete quantum architectures for large-scale, reliable quantum computers; implementation of a predictive design-tool to analyze system reliability given technology parameters and constraints; evaluation of requirements and performance of Shor's factoring algorithm on a complete benchmark quantum architecture design; and design of experimental realizations of experiments to identify crucial parameters for fault-tolerant quantum architectures.
