    "abstract": "An examination of the concept of using classical degrees of freedom to drive\nthe evolution of quantum computers is given. Specifically, when externally\ngenerated, coherent states of the electromagnetic field are used to drive\ntransitions within the qubit system, a decoherence results due to the back\nreaction from the qubits onto the quantum field. We derive an expression for\nthe decoherence rate for two cases, that of the single-qubit Walsh-Hadamard\ntransform, and for an implementation of the controlled-NOT gate. We examine the\nimpact of this decoherence mechanism on Grover\u0027s search algorithm, and on the\nproposals for use of error-correcting codes in quantum computation.",
