    "abstract": "Grover\u0027s database search algorithm, although discovered in the context of\nquantum computation, can be implemented using any system that allows\nsuperposition of states. A physical realization of this algorithm is described\nusing coupled simple harmonic oscillators, which can be exactly solved in both\nclassical and quantum domains. Classical wave algorithms are far more stable\nagainst decoherence compared to their quantum counterparts. In addition to\nproviding convenient demonstration models, they may have a role in practical\nsituations, such as catalysis.",
