Patent ID: 8484000

Claim:
A method to determine a presence of a signal of interest from among sample signals, the method comprising: receiving, by a computer, reference data that characterizes physical samples from which sample signals including a signal of interest are obtained; generating, by the computer, a measurement probe based on the reference data and based on a dynamical system that responds to excitations that are correlated with the sample signals, wherein the measurement probe is configured to enhance the signal of interest in the sample signals; injecting, by the computer, the measurement probe into a quantum mechanical system configured to receive the sample signals including the signal of interest, to convert the sample signals from a spatial domain into a spectral domain, and to enhance the signal of interest in the spectral domain due to the measurement probe the injecting comprising repeatedly injecting the measurement probe into the quantum mechanical system for a number of iterations required to collapse the quantum mechanical system; determining, by the computer, whether the injection of the measurement probe into the quantum mechanical system results in a collapse of the quantum mechanical system; and determining, by the computer, a presence of the signal of interest within the sample signals if the quantum mechanical system collapses.
