Quantum Variational Learning of the Entanglement Hamiltonian
Christian Kokail, Bhuvanesh Sundar, Torsten V. Zache +5
Learning the structure of the entanglement Hamiltonian (EH) is central to characterizing quantum many-body states in analog quantum simulation. We describe a protocol where spatial…
Theoretical and Experimental Perspectives of Quantum Verification
Jose Carrasco, Andreas Elben, Christian Kokail +2
In this perspective we discuss verification of quantum devices in the context of specific examples, formulated as proposed experiments. Our first example is verification of analog…
Entanglement Hamiltonian Tomography in Quantum Simulation
Christian Kokail, Rick van Bijnen, Andreas Elben +2
Entanglement is the crucial ingredient of quantum many-body physics, and characterizing and quantifying entanglement in closed system dynamics of quantum simulators is an outstandi…
Mixed-state entanglement from local randomized measurements
Andreas Elben, Richard Kueng, Hsin-Yuan Huang +8
We propose a method for detecting bipartite entanglement in a many-body mixed state based on estimating moments of the partially transposed density matrix. The estimates are obtain…
Many-body Chern number from statistical correlations of randomized measurements
Ze-Pei Cian, Hossein Dehghani, Andreas Elben +5
One of the main topological invariants that characterizes several topologically-ordered phases is the many-body Chern number (MBCN). Paradigmatic examples include several fractiona…
Quantum information scrambling in a trapped-ion quantum simulator with tunable range interactions
Manoj K. Joshi, Andreas Elben, Benoît Vermersch +5
In ergodic many-body quantum systems, locally encoded quantum information becomes, in the course of time evolution, inaccessible to local measurements. This concept of "scrambling"…
