Universal scaling framework for parameterized quantum evolutions at criticality
Jan T. Schneider, Cristian Tabares, Alejandro González-Tudela +1
Variational ansätze are a cornerstone of quantum many-body physics, providing compact approximations to complex ground states using finite resources. Recent quantum-technology adv…
Programming long-range interactions in analog quantum simulators
Cristian Tabares, Alberto Muñoz de las Heras, Jan T. Schneider +1
Long-range interactions are the source of many equilibrium and out-of-equilibrium quantum many-body phenomena. Analog simulators based on ionic, atomic, superconducting, and molecu…
Estimating ground-state properties in quantum simulators with global control
Cristian Tabares, Dominik S. Wild, J. Ignacio Cirac +3
Accurately determining ground-state properties of quantum many-body systems remains one of the major challenges of quantum simulation. In this work, we present a protocol for estim…
Programming optical-lattice Fermi-Hubbard quantum simulators
Cristian Tabares, Christian Kokail, Peter Zoller +2
Fermionic atoms in optical lattices provide a native implementation of Fermi-Hubbard (FH) models that can be used as analog quantum simulators of many-body fermionic systems. Recen…
