This grant will support research that will be a leap forward in advancing sound as a classical analogue of quantum information science (QIS), promoting the progress of science, and ensuring US leadership in QIS, which is a national priority. The development of robust, classically entangled acoustic waves analogous to quantum bits, or qubits, can make impactful contributions as core components of practical quantum-like technologies without suffering from quantum fragility. By exploiting recently discovered analogies between acoustics, quantum mechanics, and condensed matter physics, this research will create the foundations for a path to promising and validating modes of storing, processing, and retrieving information in acoustic waves that complement conventional quantum technologies. This grant will support the development of educational resources that bridge the educational gap between classical mechanics and quantum mechanics for future QIS learners. It will help broaden the participation of underrepresented groups in gaining a working understanding of acoustic quantum analogies and related complex quantum concepts.At the core of QIS, quantum entanglement has the property of non-separability. While non-separability creates the possibility of operating in parallel on the coherent superpositions of states for multipartite quantum systems, the quantum coherent superpositions of wave functions (probability amplitude) collapse upon measurement or thermal fluctuations. Costly solutions are cryogenics and error corrections, both use significant hardware and software resources. However, quantum computing is essentially phase computing; it exploits the possibility of achieving and rotating the coherent superpositions of states of correlated multipartite systems with complex amplitudes that are represented as vectors in large, exponentially complex Hilbert spaces. The notion of “classical entanglement” for sound waves possesses the non-separability and complexity essential to reach the promise of parallelism in quantum computing, yet without the fragility of decoherence even at room temperature. The research team will investigate metamaterials comprising arrays of externally driven, linearly and nonlinearly coupled, acoustic waveguides, known for supporting acoustic waves analogous to qubits, namely phase-bits or phi-bits. The team will experimentally, computationally, and theoretically investigate the exponentially complex and scalable Hilbert spaces of states of multiple phi-bits and the non-separability of their coherent superpositions. They will analyze the scalability and controllability of Hilbert space with billions of dimensions and their QIS applicability, and demonstrate systematic and predictable proof-of-concept operations within these Hilbert spaces to establish foundations for acoustic quantum-like gates and algorithms for future quantum-like information processing.This project is jointly funded by Dynamics, Control and Systems Diagnostics (DCSD) Program and Mechanics of Materials & Structures (MOMS) Program.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.

这笔赠款将支持研究，这将是量子信息科学（QIS）经典模拟的飞跃发展，促进科学进步，并确保美国在 QIS 领域的领导地位，这是国家优先事项。类似于量子位或量子位的经典纠缠声波可以作为实用类量子技术的核心组成部分做出有影响力的贡献，而不会受到量子脆弱性的影响。研究将为有希望和验证的声波信息存储、处理和检索模式奠定基础，以补充量子技术。这笔赠款将支持教育资源的开发，以弥合经典力学和量子力学之间的教育差距。它将有助于扩大代表性不足的群体对声学量子类比和相关复杂量子概念的理解。在 QIS 的核心，量子纠缠具有不可分离性，而不可分离性则创造了量子纠缠。对于多部分量子系统的状态相干叠加并行操作的可能性，波函数（概率幅度）的量子相干叠加在测量或热波动时崩溃，成本高昂的解决方案是低温和纠错，两者都使用大量的硬件和软件资源。然而，量子计算本质上是相位计算；它利用了实现和旋转具有复杂幅度的相关多部分系统的状态相干叠加的可能性，这些复杂幅度被表示为大型指数复杂希尔伯特空间中的向量。声波的“经典纠缠”具有实现量子计算并行性所必需的不可分离性和复杂性，但即使在室温下也不存在退相干的脆弱性。研究小组将研究由外部驱动的线性和线性阵列组成的超材料。非线性耦合声波导，以支持类似于量子位（即相位位或 phi-位）的声波而闻名，该团队将通过实验、计算和理论上研究指数级。他们将分析具有数十亿维的希尔伯特空间的可扩展性和可控性及其 QIS 适用性，并展示系统性和可预测的证明。这些希尔伯特空间中的概念操作，为未来类量子信息处理的声学类量子门和算法奠定基础。该项目由动力学、控制和系统诊断（DCSD）联合资助计划和材料与结构力学 (MOMS) 计划。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
