Systems and methods for emulating a physical quantum system with a quantum computation. A model Hamiltonian that approximates a first quantization Hamiltonian of the physical quantum system is stored in memory. The physical system includes a plurality of particles. The first quantization Hamiltonian includes a plurality of first quantization energy operators, and the model Hamiltonian includes a plurality of energy terms corresponding to respective ones of the plurality of first quantization energy operators. Each energy term includes a respective energy operator, a respective energy register operator, and a respective inverse energy operator. The physical quantum system is emulated by performing a quantum computation on a plurality of qubits of the quantum computing system to emulate time evolution using the model Hamiltonian.

The application discloses a kind of fusion multi-scale morphological and adaptive energy threshold electrocardiosignal processing method and system, comprising: obtaining electrocardiosignal, utilize multi-scale morphological filter, to electrocardiosignal Parallel signal path calculation and baseline path calculation, the morphological reconstruction signal of weighted subtraction calculation result is obtained;By non-linear energy operator to morphological reconstruction signal is amplified, and energy sequence is obtained;Energy value in energy sequence is detected gradually, if the energy value is greater than main threshold, then directly confirm as R wave, and update main threshold;If the energy value is less than main threshold, judge distance last R wave time whether greater than 1.5 times average RR interval, if not greater than, then read next energy value;Otherwise, by backtracking search to obtain backtracking maximum value, judge backtracking maximum value whether greater than auxiliary threshold, if greater than, then mark as supplementary R wave;Otherwise, read next energy value;Based on confirmed R wave, output denoised electrocardiosignal waveform and heart rate parameter.
