The Magic Barrier before Thermalization

Lukas Ebner, Berndt Müller, Andreas Schäfer +3 more·Oct 13, 2025

We investigate the time dependence of anti-flatness in the entanglement spectrum, a measure for non-stabilizerness and lower bound for non-local quantum magic, on a subsystem of a linear SU(2) plaquette chain during thermalization. Tracing the time e...

Observation of ballistic plasma and memory in high-energy gauge theory dynamics

Daniel K. Mark, Federica M. Surace, Thomas Schuster +4 more·Oct 13, 2025

Gauge theories describe the fundamental forces of nature. However, high-energy dynamics, such as the formation of quark-gluon plasmas, is notoriously difficult to model with classical methods. Quantum simulation offers a promising alternative in this...

Tensor-Network-Based Unraveling of Non-Markovian Dynamics in Large Spin Chains via the Influence Martingale Approach

Sujay Mondal, Siddhartha Dutta, Abhijit Bandyopadhyay·Oct 13, 2025

Classical simulation of open quantum system dynamics remains challenging due to the exponential growth of the Hilbert space, the need to accurately capture dissipation and decoherence, and the added complexity of memory effects in the non-Markovian r...

Analytical Control of Quantum Coherence: Markovian Revival via Basis Engineering and Exact Non-Markovian Criteria

Na-Na Zhang, Chao-Yi Wu, Ming Li +4 more·Oct 13, 2025

The preservation of quantum coherence is besieged by a fundamental dogma: its revival necessitates non-Markovian memory effects from structured environments. This paradigm has constrained quantum control strategies and obscured simpler paths to coher...
