The broader impact of this Small Business Innovation Research (SBIR) Phase II project will result from the development of a scalable, universal quantum computing platform. The range of applications are broad and will expand in parallel with the development of new quantum algorithms, with initial applications including molecular simulations for the chemical and pharmaceutical industries, currently limited by the approximations necessary to make calculations tractable for classical computers. In order to perform these simulations at a scale useful for commercial applications, quantum computing must be significantly scaled. The proposed system will develop a new method to trap and control individual atoms for scaling of quantum computers.This Small Business Innovation Research (SBIR) Phase II project will develop technology for parallel, high-fidelity single- and multi-qubit gates in neutral atom quantum computers. The technology will enable neutral atoms as a platform for scalable quantum computing technology with fault-tolerant capabilities. The proposed project includes: 1) development of systems to control atomic qubits in parallel; 2) a methodology to enact high-fidelity gates; and 3) development of necessary infrastructure for a cloud-accessed quantum computer. With a previously unrealized degree of coherent control to atomic systems, the proposed system will serve as an entirely novel tool to study many-body physics, enabling new quantum simulations of new phases of matter or high-energy physics.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.

小企业创新研究 (SBIR) 第二阶段项目的更广泛影响将源于可扩展、通用量子计算平台的开发。应用范围广泛，并将随着新量子算法的发展而扩展，最初的应用包括化学和制药行业的分子模拟，目前受到经典计算机易于计算所需的近似的限制。为了以对商业应用有用的规模执行这些模拟，必须大幅扩展量子计算。所提出的系统将开发一种新方法来捕获和控制单个原子，以扩展量子计算机的规模。这个小型企业创新研究（SBIR）第二阶段项目将开发中性原子中并行、高保真单量子位和多量子位门的技术量子计算机。该技术将使中性原子成为具有容错能力的可扩展量子计算技术的平台。 拟议的项目包括：1）开发并行控制原子量子位的系统； 2）制定高保真门的方法； 3）为云访问量子计算机开发必要的基础设施。 凭借以前未实现的对原子系统的相干控制程度，所提出的系统将作为研究多体物理学的全新工具，实现物质新阶段或高能物理学的新量子模拟。该奖项反映了 NSF 的法定使命通过使用基金会的智力优点和更广泛的影响审查标准进行评估，并被认为值得支持。
