Measuring the Rényi entropy of a two-site Fermi-Hubbard model on a trapped ion quantum computer
The efficient simulation of correlated quantum systems is a promising near-term application of quantum computers. Here, we present a measurement of the second R\'enyi entropy of the ground state of the two-site Fermi-Hubbard model on a five-qubit programmable quantum computer based on trapped ions. Our work illustrates the extraction of …
