Variational quantum eigensolvers (VQEs) are a promising class of quantum algorithms for preparing approximate ground states in near-term quantum devices. Minimizing the error in such an approximation requires designing ansatzes using physical considerations that target the studied system. One such consideration is size-extensivity. meaning that the ground state quantum correlations ar... https://www.roneverhart.com/Annie-Brocoli-Noel-en-spectacle/
