TRG Methods for Quantum Real-Time Scattering

Michael Hite; University of Iowa

In the current era of quantum computing, noise and decoherence restrict us to small systems and shallow circuit depth. As quantum computers continue to develop, we will need classical computing methods to benchmark them with. We present a novel approach for quantum real-time evolution using the tensor renormalization group, a method originally developed for statistical mechanics and lattice field theory. Using the 1D Transverse Ising Model as our test bed, we will compare one and two particle evolution with IBM's Qiskit quantum simulator and a traditional Matrix Product State approach called Time-Evolving Block Decimation.
