Cut Noise.
Work Quantum.

This paper extends Quantum Generalized Hydrodynamics (QGHD) to predict how entanglement spreads in quantum systems where particles move via random, stochastic hopping.

Understanding how entanglement evolves in the presence of noise is critical for the development of robust quantum technologies and for modeling non-equilibrium states in condensed matter physics. This work provides a rigorous mathematical bridge between purely unitary (perfectly ordered) quantum dynamics and the diffusive behaviors typically observed in classical or open quantum systems. Professionals can use these findings to better estimate the 'coherence budget' of large-scale quantum simulations affected by spatial or temporal noise.
