Enabling Quantum Leap: Q-AMASE-i: Quantum Foundry at UCSB

非技术摘要：该项目在加州大学圣巴巴拉分校建立了量子铸造厂-这是一家下一代铸造厂，开发材料和界面，托管为即将到来的基于量子的电子产品提供动力所需的相干量子态。在量子计算、量子传感和其他基于量子信息的应用中，新兴的技术前沿要求超越只处理单一经典态(例如比特)的传统电子学，而是访问多个叠加或纠缠的量子态(例如量子比特)。利用量子信息的这种多态范式需要开发新的材料，这些材料既能够容纳这些复杂的量子态，又能够保护它们的信息不会因环境退相干而丢失。Quantum Foundry通过(1)创造工具来创建和测量具有受保护的量子相干态的材料，以及(2)通过开发这些材料以避免其受控量子态的退相干，从而解决了这一挑战。在Foundry进行的研究开发了具有自然保护的相干性的量子电子态的宿主材料，进一步稳定了这些受保护的态在界面上，并设计了将其量子相干性传播到传统信息网络的方法。这些主题是Foundry工业合作伙伴的核心利益，所有这些合作伙伴都与Foundry运营的各个层面交织在一起，以最大限度地发挥其在不断增长的量子信息技术领域的影响。关键是Foundry的计划，即培训一支能够在这一新领域的前沿推动创新的多样化量子劳动力。特别是，量子信息科学研究生培训的重新构想和跨学科计划，与以量子为基础的本科生研究培训和针对不同社区的外联活动相结合，是量子铸造厂使命的重点。技术摘要：该项目为即将到来的基于量子信息的电子学时代建立了一个材料铸造厂。加州大学圣巴巴拉分校的量子铸造厂通过整合一系列跨学科的专业知识，支持关键的新工具开发，并利用加州大学圣巴巴拉分校和网络合作伙伴的庞大材料开发基础设施网络，旨在开发形成基于量子信息的设备和应用(例如，基于量子的计算和传感)的骨干所需的材料。实现这一愿景的关键是，Foundry开发块状晶体和薄膜材料，这些材料本身就包含具有受保护相干的量子电子态(如非阿贝尔任意子态)，在可扩展的界面上使这些和其他纠缠/叠加态具有功能化，并设计出在网络中传播量子相干的方法。例如，从开发拥有拓扑保护的非阿贝尔态的新形式的拓扑超导体，到开发用于操纵高度相干的局域量子态的平台。Foundry创新并利用新的工具来生长产生相干量子态的原始材料，以及用于表征其相干和纠缠的新工具。跨学科的理论、计算和数据科学的努力进一步支撑和指导了Foundry的研究，工业合作伙伴在Foundry的整个运营过程中相互交织。与这些行业合作伙伴的协同效应是Foundry加快国家量子技术经济部门发展的愿景的核心，而Foundry的一个关键目标是培训一支有量子能力的劳动力。Foundry新颖的量子信息科学研究生培训计划及其基于量子的本科生研究培训/拓展活动旨在建立一支多样化的下一代劳动力-能够利用基于量子的技术发展而出现的科学和商业机会的劳动力。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

Nontechnical Abstract: This project establishes the Quantum Foundry at UC Santa Barbara---a next generation foundry that develops materials and interfaces hosting the coherent quantum states needed to power the coming age of quantum-based electronics. Emerging technological frontiers in quantum computation, quantum sensing, and other quantum information-based applications require moving beyond conventional electronics, which address only a single classical state (e.g. a bit), and to instead access multiple superimposed or entangled quantum states (e.g. a quantum bit). Harnessing this multistate paradigm of quantum information requires the development of new materials that are capable of both hosting these complex quantum states and of protecting their information from being lost via environmental decoherence. The Quantum Foundry addresses this challenge through (1) the creation of tools for creating and measuring materials possessing protected quantum coherent states and (2) through developing these materials such that the decoherence of their controlled quantum states can be avoided. Research conducted in the Foundry develops materials that host quantum electronic states with natively protected coherence, further stabilizes these protected states at interfaces, and also engineers the means of propagating their quantum coherence into conventional information networks. These topics are core interests of the Foundry's industrial partners, all of whom are intertwined within all levels of the Foundry's operations to maximize its impact in the growing quantum information technologies sector. Key to this is the Foundry's program of training a diverse quantum workforce capable of driving innovation at the frontiers of this new sector. In particular, a reimagined and interdisciplinary program of graduate training in quantum information science combined with quantum-based undergraduate research training and outreach activities targeted at diverse communities is a focus of the Quantum Foundry's mission. Technical Abstract: This project establishes a materials foundry for the coming age of quantum information-based electronics. Through integrating a convergent array of interdisciplinary expertise, enabling critical new tool development, and leveraging a vast network of materials development infrastructure at UCSB and with network partners, the Quantum Foundry at UC Santa Barbara aims to develop the materials required to form the backbone of quantum information-based devices and applications (e.g., quantum-based computing and sensing). Key to realizing this vision, the Foundry develops both bulk crystalline and thin film materials that natively host quantum electronic states with protected coherence (such as non-abelian anyon states), functionalizes these and other entangled/superposition states at scalable interfaces, and engineers the means of propagating their quantum coherence across networks. Examples range from the development of new forms of topological superconductors hosting topologically protected non-abelian states to developing platforms for manipulating highly coherent, localized quantum states. The Foundry innovates and harnesses new tools for growing pristine materials that engender coherent quantum states as well as new instruments for characterizing their coherence and entanglement. Interdisciplinary theoretical, computational, and data science efforts further underpin and guide the Foundry's research, and industrial partners are intertwined throughout the Foundry's operation. Synergies with these industry partners are core to the Foundry's vision of accelerating the development of the nation's quantum technologies economic sector, and a key goal of the Foundry is the training of a quantum-capable workforce. The Foundry's novel graduate training program in quantum information science and its quantum-based undergraduate research training/outreach activities are targeted at building a diverse, next generation workforce---one capable of harnessing the scientific and commercial opportunities that arise as quantum-based technologies develop.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.
