Exact Many-body Quantum Dynamics in One-Dimensional Baths via Collective Spins
Joseph T. Lee, Silvia Cardenas-Lopez, Stuart J. Masson +2
Computing the exact dynamics of many-body quantum systems becomes intractable as system size grows. Here, we present a symmetry-based method that provides an exponential reduction…

Test of the unitary coupled-cluster variational quantum eigensolver for a simple strongly correlated condensed-matter system
Luogen Xu, Joseph T. Lee, J. K. Freericks
The variational quantum eigensolver has been proposed as a low-depth quantum circuit that can be employed to examine strongly correlated systems on today's noisy intermediate-scale…
