Backpropagating Pauli Propagation
Sheng-Hsuan Lin, Etienne Granet, Kevin Hémery +1
The paper presents a backpropagation algorithm that computes parameter gradients in quantum circuits via Pauli propagation, achieving similar computational cost to sparse Pauli sim…
Dynamical structure factor with a pumping approach on a trapped-ion quantum computer
Etienne Granet, Keisuke Murota, Henrik Dreyer +3
Dynamical structure factors (DSF) measured with neutron-scattering experiments provide key insights into the structure of materials. Their computation requires both the preparation…
Spectral functions on a quantum computer through system-environment interaction
Etienne Granet, Ramil Nigmatullin, David T. Stephen +1
Spectral functions measured with angle-resolved photoemission spectroscopy (ARPES) provide key insight to elucidate the band structure of materials. Comparison with theory requires…
Digital quantum magnetism on a trapped-ion quantum computer
Reza Haghshenas, Eli Chertkov, Michael Mills +56
Digital quantum matter -- realized when discrete quantum gates approximate continuous time evolution -- is susceptible to heating into chaotic, structureless states. If digitizatio…
Adiabatic preparation of thermal states and entropy-noise relation on noisy quantum computers
Etienne Granet, Henrik Dreyer
We consider the problem of preparing thermal equilibrium states at finite temperature on quantum computers. Assuming thermalization, we show that states that are locally at thermal…
Effect of slowly decaying long-range interactions on topological qubits
Etienne Granet, Michael Levin
We study the robustness of topological ground state degeneracy to long-range interactions in quantum many-body systems. We focus on slowly decaying two-body interactions that scale…
