Abstract: Quantum state signal for most time is Non-orthogonal signal; it's not fit to applying the classical signal processing methods to their signal analyzing and estimating. In accordance with this, we discussed a basic model for pure quantum signal processing. By combining the least-squares estimation and Positive-Operator-Valued Measure, we furthermore developed a novel quantum detection method for non-orthogonal state signal. The simulation test result in addition verified its effectiveness.

 

Keywords: Signal processing, Quantum detection, Non-orthogonal state, Least-square estimation, POVM.
