QuSeC-TAQS: Noise Engineering For Enhanced Quantum Sensing

从根本上理解量子现象是非常有趣的，因为这些现象在从量子信息处理到磁共振成像的应用中都很重要。这个项目将探索量子尺度上的电子噪声，是什么环境因素控制它，然后如何通过设计来控制它。在更大的量子技术研究领域，这些信息将使设计有效的量子比特用于信息处理和生物医学传感应用成为可能。在科学之外，这项工作将建立以量子信息科学与工程（QISE）为重点的课程，以广泛分发，并组织一个以量子信息科学与工程为重点的本地研讨会，以理解量子水平的噪声。该项目的技术目标是在原子水平上实现快速、有效的磁噪声分析。在量子计算机和传感器的当前状态下，这种规模的噪声是一个关键挑战，因为噪声会导致退相干，从而破坏量子比特的效用。为了处理上述噪音，技术人员需要了解它：噪音的频率，噪音的大小，以及产生噪音的原因。该项目由来自科罗拉多大学博尔德分校和科罗拉多州立大学的跨学科化学和物理团队组成，将探索一种有效表征噪声的新技术，并通过光谱和理论方法对固态量子比特（如钻石中的NV中心）和含金属分子的新方法进行基准测试。这些研究将把对磁噪声的理解扩展到原子水平，超越目前已知的边界。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。

Understanding fundamentally quantum phenomena is of high interest because those phenomena are important in applications that span from quantum information processing to magnetic resonance imaging. This project will explore electronic noise at the quantum scale, what environmental factors control it, and then how to control it by design. In the larger landscape of quantum technology research, this information will enable the design of effective quantum bits for information processing and biomedical sensing applications. Beyond science, this effort will build curricula focused on quantum information science and engineering (QISE) for wide distribution and organize a local QISE-focused workshop on understanding noise at the quantum level. The technical goal of this project is to enable fast, efficient profiling of magnetic noise at the atomic level. Noise at this scale is a critical challenge in the current state of quantum computers and sensors because noise causes decoherence which destroys a qubit’s utility. To deal with said noise, technologists need to understand it: what frequency is the noise, how loud is is, and what causes it. This project, comprising an interdisciplinary chemistry and physics team from University of Colorado Boulder and Colorado State University, will explore a new technique for the efficient characterization of noise and benchmark the new method with both solid-state qubits (like the NV center in diamond) and metal-containing molecules through spectroscopic and theoretical methods. These studies will extend the understanding of magnetic noise to an atomistic level beyond the border of what it currently known.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.
