Post-Critical Meson Dynamics of Kibble-Zurek Excitations in a 5,564-Qubit Quantum Annealer

Francis A. Bayocboc, Jacek Dziarmaga, Marek M. Rams +1

Quantum phase transitions provide a controlled route for generating many-body excitations, but the dynamics after the critical point can be as important as the initial defect creat…

Approaching the scaling limit of transport through lattices with dephasing

Subhajit Sarkar, Gabriela Wójtowicz, Bartłomiej Gardas +2

We examine the stationary--state equations for lattices with generalized Markovian dephasing and relaxation. When the Hamiltonian is quadratic, the single--particle correlation mat…

Finite temperature dopant-induced spin reorganization explored via tensor networks in the two-dimensional - model

Yintai Zhang, Aritra Sinha, Marek M. Rams +1

We study the two-dimensional -- model at finite temperature directly in the thermodynamic limit using purification represented by an infinite projected entangled-pair state (…

Evaluating the Limits of QAOA Parameter Transfer at High-Rounds on Sparse Ising Models With Geometrically Local Cubic Terms

Elijah Pelofske, Marek Rams, Andreas Bärtschi +4

The emergent practical applicability of the Quantum Approximate Optimization Algorithm (QAOA) for approximate combinatorial optimization is a subject of considerable interest. One…

Quantum Fisher information from tensor network integration of Lyapunov equation

Gabriela Wójtowicz, Susana F. Huelga, Marek M. Rams +1

The Quantum Fisher Information (QFI) is a geometric measure of state deformation calculated along the trajectory parameterizing an ensemble of quantum states. It serves as a key co…

Comment on: "Dynamics of disordered quantum systems with two- and three-dimensional tensor networks" arXiv:2503.05693

Andrew D. King, Alberto Nocera, Marek M. Rams +8

In a recent preprint [1] (arXiv:2503.05693), Tindall et al. presented impressive classical simulations of quantum dynamics using tensor networks. Their methods represent a signific…
