Fermionic correlation functions from randomized measurements in programmable atomic quantum devices
arXiv:2205.00981 · doi:10.1103/PhysRevLett.131.060601
Abstract
We provide a measurement protocol to estimate 2- and 4-point fermionic correlations in ultra-cold atom experiments. Our approach is based on combining random atomic beam splitter operations, which can be realized with programmable optical landscapes, with high-resolution imaging systems such as quantum gas microscopes. We illustrate our results in the context of the variational quantum eigensolver algorithm for solving quantum chemistry problems.
