Design and Experimental Demonstration of a Scalable Acoustic Analogue of Quantum Computers

Computers have transformed the way we live, work, and innovate. While Quantum computers based on quantum bits (qubits) exploit principles such as superposition and entanglement to offer unprecedented computational power compared to conventional computers. However, their scalability and practical realization are limited by challenges associated with wavefunction decoherence, the need for cryogenic temperatures, and extreme sensitivity to noise and environmental disturbances. The analogy between topological acoustic waves and quantum mechanics offers a path toward the design and operation of an acoustic quantum-analogue computer which does not suffer from the fragility of qubits. In this work, we present the demonstration and characterization of such a scalable, cost-effective, room-temperature acoustic analogue quantum computing platform. This platform harnesses the intrinsic nonlinearity of physical systems to generate wave superposition. We demonstrate several scalable quantum operations, including the realization of quantum permutation gates and quantum-inspired cryptography, using experimental results from this system. In addition, we discuss the underlying concepts and characterization of the platform, along with the ongoing efforts both through analytical simulation in ANSYS mechanical and experimental validation to develop a model of the acoustic quantum analogue computer. Finally, the dissertation concludes with an assessment of the platform’s reliability and robustness, highlighting its promise as a practical alternative for quantum-inspired computation.
