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…
Celestial soft currents at one-loop and their OPEs
Rishabh Bhardwaj, Akshay Yelleshpur Srikant
Conformally soft operators and their associated soft theorems on the celestial sphere encode the low energy behaviour of bulk scattering amplitudes. They lead to an infinite dimens…
A double copy from twisted (co)homology at genus one
Rishabh Bhardwaj, Andrzej Pokraka, Lecheng Ren +1
We study the twisted (co)homology of a family of genus-one integrals -- the so called Riemann-Wirtinger integrals. These integrals are closely related to one-loop string amplitudes…
