Initial states for quantum field simulations in phase space
Peter D. Drummond, Bogdan Opanchuk · Physical Review Research · 2020
This paper studies methods for numerical simulations of many-body quantum systems, useful for simulating photonic networks and some quantum computers. The authors show that different phase-space methods have an exponentially large range of efficiency and speed for computing high-order correlations. The results can be either exponentially faster or slower than experimental measurement.
