Forte: A Suite of Advanced Multireference Quantum Chemistry Methods
Francesco A. Evangelista, Chenyang Li, Prakash Verma +14
Forte is an open-source library specialized in multireference electronic structure theories for molecular systems and the rapid prototyping of new methods. This paper gives an over…
A stochastic quantum Krylov protocol with double factorized Hamiltonians
Nicholas H. Stair, Cristian L. Cortes, Robert M. Parrish +2
We propose a class of randomized quantum Krylov diagonalization (rQKD) algorithms capable of solving the eigenstate estimation problem with modest quantum resource requirements. Co…
QForte: an efficient state simulator and quantum algorithms library for molecular electronic structure
Nicholas H. Stair, Francesco A. Evangelista
We introduce a novel open-source software package QForte, a comprehensive development tool for new quantum simulation algorithms. QForte incorporates functionality for handling mol…
Simulating Many-Body Systems with a Projective Quantum Eigensolver
Nicholas H. Stair, Francesco A. Evangelista
We present a new hybrid quantum-classical algorithm for optimizing unitary coupled-cluster (UCC) wave functions deemed the projective quantum eigensolver (PQE), amenable to near-te…
Exploring Hilbert space on a budget: Novel benchmark set and performance metric for testing electronic structure methods in the regime of strong correlation
Nicholas H. Stair, Francesco A. Evangelista
This work explores the ability of classical electronic structure methods to efficiently represent (compress) the information content of full configuration interaction (FCI) wave fu…
A Multireference Quantum Krylov Algorithm for Strongly Correlated Electrons
Nicholas H. Stair, Renke Huang, Francesco A. Evangelista
We introduce a multireference selected quantum Krylov (MRSQK) algorithm suitable for quantum simulation of many-body problems. MRSQK is a low-cost alternative to the quantum phase…
