GENERALIZED ENTANGLEMENT FORGING WITH SLATER DETERMINANTS

Abstract

Systems and techniques that facilitate generalized entanglement forging (GEF) of an electronic structure are provided. For example, one or more embodiments described herein can comprise a system, which can comprise a memory that can store computer executable components. The system can also comprise a processor, operably coupled to the memory that can execute at least one of the computer executable components that can generalize entanglement forging of an electronic structure for quantum operations, wherein GEF comprises initializing a calculation with a set of classical reference states, wherein the set of classical reference states are non-orthogonal Slater determinants. GEF can further comprise: correlating, on a quantum system, the set of classical reference states using a local unitary cluster Jastrow ansatz, wherein the Jastrow ansatz is initialized from a classical electronic structure calculation; and minimizing an energy function over a set of variational parameters of a wavefunction that represents the electronic structure.
