Contracted Quantum Eigensolver for the Quantum Simulation of Many-Electron Systems
Offered By: Institute for Pure & Applied Mathematics (IPAM) via YouTube
Course Description
Overview
Explore a 42-minute lecture on the Contracted Quantum Eigensolver (CQE) for quantum simulation of many-electron systems. Delve into this novel hybrid quantum-classical algorithm presented by David Mazziotti from the University of Chicago's Chemistry department at IPAM's Large-Scale Certified Numerical Methods in Quantum Mechanics Workshop. Learn about the CQE's advantages over variational quantum eigensolvers, its potential for exponential speed-up, and its application in resolving ground-state energies of benzyne isomers using IBM quantum processing units. Discover error-mitigation strategies, the integration of classical 2-RDM methods for total electron correlation, and the application of anti-Hermitian contracted Schrödinger equation (ACSE) and multi-component pair density functional (MC-PDFT) theories. Gain insights into molecular simulations, hardware-efficient onsets, and the accuracy of quantum eigensolvers in this comprehensive exploration of cutting-edge quantum computational methods.
