Robust spin-squeezing with random interaction graphs: the lesson from universality

Andrea Solfanelli, Augusto Smerzi, Peter Zoller +1

We establish the conditions under which scalable spin squeezing can be achieved in interacting spin ensembles embedded in arbitrary, inhomogeneous graph geometries. We identify two…

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…

Bounded-Error Quantum Simulation via Hamiltonian and Lindbladian Learning

Tristan Kraft, Manoj K. Joshi, William Lam +11

Analog Quantum Simulators offer a route to exploring strongly correlated many-body dynamics beyond classical computation, but their predictive power remains limited by the absence…

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…

Hamiltonian and Liouvillian learning in weakly-dissipative quantum many-body systems

Tobias Olsacher, Tristan Kraft, Christian Kokail +2

We discuss Hamiltonian and Liouvillian learning for analog quantum simulation from non-equilibrium quench dynamics in the limit of weakly dissipative many-body systems. We present…

Quantum Simulation of 2D Quantum Chemistry in Optical Lattices

Javier Argüello-Luengo, Alejandro González-Tudela, Tao Shi +2

Benchmarking numerical methods in quantum chemistry is one of the key opportunities that quantum simulators can offer. Here, we propose an analog simulator for discrete 2D quantum…

Self-Verifying Variational Quantum Simulation of the Lattice Schwinger Model

Christian Kokail, Christine Maier, Rick van Bijnen +8

Hybrid classical-quantum algorithms aim at variationally solving optimisation problems, using a feedback loop between a classical computer and a quantum co-processor, while benefit…

Rényi Entropies from Random Quenches in Atomic Hubbard and Spin Models

Andreas Elben, Benoît Vermersch, Marcello Dalmonte +2

We present a scheme for measuring Rényi entropies in generic atomic Hubbard and spin models using single copies of a quantum state and for partitions in arbitrary spatial dimension…
