量子计算机可以帮助解决物理、化学、材料设计、优化和机器学习中的一些最复杂的问题。构建量子计算机 的主要挑战之一是在 量子噪声存在的情况下展示强大的量子信息处理。在过去的十年中，在实现容错量子 计算方面取得了巨大的理论和实验进展 。虽然 这些进步使几个原理证明逻辑量子比特 实验成为可能，但将量子系统扩展到许多应用所需的逻辑量子比特的 数量和质量需要新一代的系统工具流。 这个项目的目标是 开发一个基于 异质超导量子比特的实用架构，以及它的关键编译和基准测试 工具， 这将允许应用程序在需要 更少的资源的情况下执行容错，在 近期硬件上实现实用量子 优势的目标。教育和外展活动将朝着创造从K-12到研究生水平的持续和可持续的管道取得进展。该项目设想了一种基于 超导电路的容错架构，其中廉价、嘈杂的量子比特和昂贵的 纠错量子比特可以共存。将 开发智能编译软件，将应用程序映射到这种异构体系结构上， 同时实现 显著的容错资源节约。通过深入吸取 量子信息和计算机体系结构的思想， 该计划为跨学科合作创造了新的 机会，并通过 公开讲座、软件库和 外展活动向更广泛的 受众展示量子计算。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

Quantum computers can help solve some of the most complex problems in physics, chemistry, material design, optimization, and machine learning. One of the leading challenges in building quantum computers is to demonstrate robust quantum information processing in the presence of quantum noise. In the last decade, tremendous theoretical and experimental progress has been made toward realizing fault tolerant quantum computation. While these advances have made possible several proof-of-principle logical qubit experiments, scaling quantum systems to the quantity and quality of logical qubits needed by many applications requires a new generation of systems tool flows. The goal of this project is to develop a practical architecture based on heterogeneous superconducting qubits, as well as its crucial compiling and benchmarking tools, that will allow applications to be executed fault tolerantly while requiring fewer resources, bringing closer the goals of practical quantum advantage on near-term hardware. Education and outreach activities will make advances toward creating a sustained and sustainable pipeline from K-12 through graduate levels. This project envisions a fault-tolerant architecture based on superconducting circuits where cheap, noisy qubits and expensive, error-corrected qubits can co-exist. Intelligent compilation software will be developed to map applications onto this heterogeneous architecture, while achieving significant resource savings for fault tolerance. By drawing deeply on ideas from quantum information and computer architecture, the program creates new opportunities for interdisciplinary collaboration and exposes a broader audience to quantum computing through open lectures, software libraries, and outreach events.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
