Collaborative Research: CQIS: A Sound Leap (SouL)

这笔赠款将支持研究，这将是一个飞跃，推进声音作为量子信息科学（QIS）的经典模拟，促进科学的进步，并确保美国在QIS的领导地位，这是一个国家优先事项。 类似于量子比特或量子比特的鲁棒、经典纠缠声波的发展，可以作为实用类量子技术的核心组件做出有影响力的贡献，而不会受到量子脆弱性的影响。通过利用最近发现的声学、量子力学和凝聚态物理学之间的类比，这项研究将为一条有前途和有效的存储、处理和检索声波中信息的模式奠定基础，这些模式将补充传统的量子技术。这笔赠款将支持教育资源的开发，为未来的QIS学习者弥合经典力学和量子力学之间的教育差距。这将有助于扩大代表性不足的群体的参与，以获得声学量子类比和相关的复杂量子概念的工作理解。在QIS的核心，量子纠缠具有不可分离性。虽然不可分性为多体量子系统的相干叠加态创造了并行操作的可能性，但波函数（概率振幅）的量子相干叠加会在测量或热波动时崩溃。昂贵的解决方案是低温和错误校正，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振幅的相关多体系统的状态的相干叠加的可能性，这些复振幅表示为大型指数复希尔伯特空间中的向量。声波的“经典纠缠”概念具有不可分离性和复杂性，这对于实现量子计算中的并行性至关重要，但即使在室温下也没有退相干的脆弱性。该研究小组将研究由外部驱动的线性和非线性耦合声波波导阵列组成的超材料，该超材料以支持类似于量子比特的声波而闻名，即相位比特或Φ比特。该团队将通过实验、计算和理论研究多个Φ比特状态的指数复杂和可扩展的希尔伯特空间及其相干叠加的不可分离性。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，并在这些希尔伯特空间中展示系统和可预测的概念验证操作，为未来的类量子信息处理奠定声学量子门和算法的基础。&该奖项反映了NSF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。

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.
