    "abstract": "Quantum search is a quantum mechanical technique for searching N\npossibilities in only sqrt(N) steps. This paper gives a fresh perspective on\nthe algorithm in terms of a resonance phenomenon which is implemented through\nclassical coupled oscillators. Consider N oscillators, one of which is of a\ndifferent resonant frequency. We could identify which one this is by measuring\nthe oscillation frequency of each oscillator, a procedure that would take about\nN cycles. We show how, by coupling the oscillators together in a very simple\nway, it is possible to identify the different one in only sqrt(N) cycles. An\nextension of this technique to the quantum case leads to the quantum search\nalgorithm.",
