Gibbs state postulate from dynamical stability
Vjosa Blakaj, Matthias C. Caro, Anouar Kouraich +2
Gibbs states play a central role in quantum statistical mechanics as the standard description of thermal equilibrium. Traditionally, their use is justified either by a heuristic, a…
Renormalization-group-based preparation of matrix product states on up to 80 qubits
Moritz Scheer, Alberto Baiardi, Elisa Bäumer Marty +2
A key challenge for quantum computers is the efficient preparation of many-body entangled states across many qubits. In this work, we demonstrate the preparation of matrix product…
Gaussian tomography for cold-atom simulators
Matthew Kiser, Max McGinley, Daniel Malz
A limitation of analog quantum simulators based on cold atoms in optical lattices is that readout is typically limited to observables diagonal in the charge basis, i.e., densities…
Estimating applied potentials in cold atom lattice simulators
Bhavik Kumar, Daniel Malz
Cold atoms in optical lattices are a versatile and highly controllable platform for quantum simulation, capable of realizing a broad family of Hubbard models, and allowing site-res…
Robust Superradiance and Spontaneous Spin Ordering in Disordered Waveguide Quantum Electrodynamics
Xin H. H. Zhang, Daniel Malz, Peter Rabl
We study the collective emission of a disordered array of excited two-level atoms into a one-dimensional photonic waveguide. In the perfectly ordered case, where atoms are spac…
Measurement-induced entanglement in noisy 2D random circuits
Zhi-Yuan Wei, Jon Nelson, Joel Rajakumar +4
We study measurement-induced entanglement (MIE) generated by column-by-column sampling of noisy 2D random circuits of size and depth . Focusing primarily on Clifford circuit…
Computational complexity of injective projected entangled pair states
Dylan Harley, Freek Witteveen, Daniel Malz
Projected entangled pair states (PEPS) constitute a variational family of quantum states with area-law entanglement. PEPS are particularly relevant and successful for studying grou…
Random Permutation Circuits Beyond Qubits are Quantum Chaotic
Bruno Bertini, Katja Klobas, Pavel Kos +1
Random permutation circuits were recently introduced as minimal models for local many-body dynamics that can be interpreted both as classical and quantum. Standard dynamical comple…
Unraveling superradiance: Entanglement and mutual information in collective decay
Xin H. H. Zhang, Daniel Malz, Peter Rabl
We study the collective decay of an initially inverted ensemble of two-level emitters in two distinct scenarios: when coupled to a squeezed photonic reservoir and when interacting…
State preparation with parallel-sequential circuits
Zhi-Yuan Wei, Daniel Malz
We introduce parallel-sequential (PS) circuits, a family of quantum circuit layouts that interpolate between brickwall and sequential circuits, which introduces control parameters…
