Abstract: A novel approach for computing efficiently quantum based signal autocorrelations includes example designs associated with quantum circuits for computing the quantum autocorrelation of the signal. Importantly, to compensate for unique challenges associated with quantum signal processing (particularly regarding probabilistic measurements that result from QFT and IQFT operations), normalization and denormalization steps ensure that quantum measurement results are comparable to ranges that would be obtained with classical autocorrelation computation methods. In addition, because probabilistic measurements resulting from QFT and IQFT operations lose important phase information, lost phase information can be restored following measurement using QFT and IQFT.
