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…
Dynamical preparation of laser-excited anisotropic Rydberg crystals in 2D optical lattices
Benoît Vermersch, Matthias Punk, Alexander W. Glaetzle +2
We describe the dynamical preparation of anisotropic crystalline phases obtained by laser-exciting ultracold Alkali atoms to Rydberg p-states where they interact via anisotropic va…
Interference of Bose condensates
M. Naraschewski, H. Wallis, A. Schenzle +2
We investigate the prospects of atomic interference using samples of Bose condensed atoms. First we show the ability of two independent Bose condensates to create an interference p…
