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…
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"…
Cross-Platform Verification of Intermediate Scale Quantum Devices
Andreas Elben, Benoît Vermersch, Rick van Bijnen +7
We describe a protocol for cross-platform verification of quantum simulators and quantum computers. We show how to measure directly the overlap an…
