Macroscopic Particle Transport in Dissipative Long-Range Bosonic Systems
Hongchao Li, Cheng Shang, Tomotaka Kuwahara +1
Dissipation in quantum many-body systems provides a more general and experimentally realistic perspective on particle transport than closed quantum systems. In this work, we determ…
Spectral Small-Incremental-Entangling: Breaking Quasi-Polynomial Complexity Barriers in Long-Range Interacting Systems
Donghoon Kim, Yusuke Kimura, Hugo Mackay +6
How the detailed structure of quantum complexity emerges from quantum dynamics remains a fundamental challenge highlighted by advances in quantum simulators and information process…
Operator Spreading and Information Propagation: Equivalence and Beyond
Cheng Shang, Zhi-Guang Lu, Hayato Kinkawa +1
We investigate the quantitative relationship between operator spreading and classical information propagation in quantum systems. Focusing on a bi-partite quantum channel, we deriv…
