Thermodynamic-limit dispersion relations on trapped-ion quantum hardware
Lucas Marti, Sumeet, Stefan Wolf +2
We run a numerical linked-cluster expansion with a quantum algorithm (NLCE+QA), computing ground-state energies and one quasi-particle dispersions in the thermodynamic limit using…

Shallow-depth GHZ state generation on NISQ devices
S. Siddardha Chelluri, Stephan Schuster, Sumeet +1
In this work, we focus on GHZ state generation under the practical constraint of limited qubit connectivity, a hallmark of current NISQ hardware. We study the GHZ state preparation…

Hybrid quantum-classical algorithm for the transverse-field Ising model in the thermodynamic limit
Sumeet, M. Hörmann, K. P. Schmidt
We describe a hybrid quantum-classical approach to treat quantum many-body systems in the thermodynamic limit. This is done by combining numerical linked-cluster expansions (NLCE)…
