Derandomized shallow shadows: Efficient Pauli learning with bounded-depth circuits
Katherine Van Kirk, Christian Kokail, Jonathan Kunjummen +7
Efficiently estimating large numbers of non-commuting observables is an important subroutine of many quantum science tasks. We present the derandomized shallow shadows (DSS) algori…
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…
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…
