Post-Critical Meson Dynamics of Kibble-Zurek Excitations in a 5,564-Qubit Quantum Annealer
Francis A. Bayocboc, Jacek Dziarmaga, Marek M. Rams +1
The authors use a 5,564‑qubit superconducting quantum annealer to investigate how Kibble‑Zurek defects evolve after a quantum phase transition in a longitudinally biased Ising chai…
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…
Beyond-classical computation in quantum simulation
Andrew D. King, Alberto Nocera, Marek M. Rams +60
Quantum computers hold the promise of solving certain problems that lie beyond the reach of conventional computers. However, establishing this capability, especially for impactful…
Approaching the scaling limit of transport through lattices with dephasing
Subhajit Sarkar, Gabriela Wójtowicz, BartÅomiej 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…
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…
