Learning Low-Energy Subspace Overlaps in Many-Body Systems with Measurement-Based and Coherent Quantum Strategies
Shamminuj Aktar, Rishabh Bhardwaj, Tanmoy Bhattacharya +1
Predicting the overlap of quantum states with specified low-energy subspaces is a key diagnostic for quantum many-body dynamics, with direct applications in state preparation, subs…
Fault tolerant computation of the static structure factor and finite size effects
Rishabh Bhardwaj, Alexander Reed Muñoz, Travis E. Jones +1
Fault-tolerant quantum algorithms offer a promising pathway for estimating the ground-state energies of periodic materials that are beyond the practical reach of classical electron…
The Quantum Hamiltonian Analysis Toolkit: Lowering the Barrier to Quantum Computing with Hamiltonians
Brendan K. Krueger, Stephan Eidenbenz, Shamminuj Aktar +8
We present the Quantum Hamiltonian Analysis Toolkit (QHAT), a newly developed application that provides a user-friendly interface for studying Hamiltonians and performing Hamiltoni…
Fault-tolerant simulation of the electronic structure using Projector Augmented-Waves and Bloch orbitals
Rishabh Bhardwaj, Alexander Reed Muñoz, Travis E. Jones +1
Strongly correlated materials are a natural target for fault-tolerant quantum computers, but they require tools beyond those developed for molecules. Electronic wavefunctions vary…
