Electronic Properties of Single-Layer CoO/Au(111)

Ann Julie U. Holt, Sahar Pakdel, Jonathan Rodríguez-Fernández +11

We report direct measurements via angle-resolved photoemission spectroscopy (ARPES) of the electronic dispersion of single-layer CoO. The Fermi contour consists of a large hole…

Adaptive Variational Quantum Imaginary Time Evolution Approach for Ground State Preparation

Niladri Gomes, Anirban Mukherjee, Feng Zhang +5

An adaptive variational quantum imaginary time evolution (AVQITE) approach is introduced that yields efficient representations of ground states for interacting Hamiltonians on near…

Adaptive Variational Quantum Dynamics Simulations

Yong-Xin Yao, Niladri Gomes, Feng Zhang +4

We propose a general-purpose, self-adaptive approach to construct variational wavefunction ansätze for highly accurate quantum dynamics simulations based on McLachlan's variational…

Bypassing the computational bottleneck of quantum-embedding theories for strong electron correlations with machine learning

John Rogers, Tsung-Han Lee, Sahar Pakdel +5

A cardinal obstacle to performing quantum-mechanical simulations of strongly-correlated matter is that, with the theoretical tools presently available, sufficiently-accurate comput…

Shallow-circuit variational quantum eigensolver based on symmetry-inspired Hilbert space partitioning for quantum chemical calculations

Feng Zhang, Niladri Gomes, Noah F. Berthusen +4

Development of resource-friendly quantum algorithms remains highly desirable for noisy intermediate-scale quantum computing. Based on the variational quantum eigensolver (VQE) with…

Efficient step-merged quantum imaginary time evolution algorithm for quantum chemistry

Niladri Gomes, Feng Zhang, Noah F. Berthusen +4

We develop a resource efficient step-merged quantum imaginary time evolution approach (smQITE) to solve for the ground state of a Hamiltonian on quantum computers. This heuristic m…
