Description
Quantum computers can produce real time correlators of field theories. We adapt the generalized eigenvalue problem to these real-time correlators in order to extract energy eigenvalues. We test the method with both simulations in classical computers and on actual quantum hardware. We are able to resolve several low-lying energy levels, in agreement with exact diagonalization results. We also compare our results the energy level extractions by Fourier transforming the time-dependence of the signals and show that our method is far more efficient.
