Real-Space Quantum Chemistry on Quantum Devices

Watch this 52-minute lecture where Stijn De Baerdemacker from the University of New Brunswick presents his research on "Real-space quantum chemistry on quantum devices" at IPAM's Optimal Transport for Density Operators workshop at UCLA. Recorded on April 3, 2025, the talk explores limitations of the current orbital-picture paradigm in quantum chemical implementations and introduces an alternative grid-based approach for implementing wavefunctions and density matrices on digital quantum devices. The presentation covers joint research with Ehsan Ghasempouri and Gerhard Dueck, addressing how this approach can enhance versatility in both Variational Quantum Eigensolver (VQE) and Quantum Phase Estimation (QPE) contexts.
