Optimal low-rank compression of quantum dynamics
Hugo Mackay, Donghoon Kim, Tan Van Vu +1
Local quantum interactions generate dynamics in an exponentially large Hilbert space, yet locality and entanglement restrict the information that can spread and accumulate. Bounds…
Universal Precision Limits in General Open Quantum Systems
Tan Van Vu, Ryotaro Honma, Keiji Saito
The intuition that the precision of observables is constrained by thermodynamic costs has recently been formalized through thermodynamic and kinetic uncertainty relations. While su…
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…
Fidelity-dissipation relations in quantum gates
Tan Van Vu, Tomotaka Kuwahara, Keiji Saito
Accurate quantum computing relies on the precision of quantum gates. However, quantum gates in practice are generally affected by dissipative environments, which can significantly…
Optimal light cone for macroscopic particle transport in long-range systems: A quantum speed limit approach
Tan Van Vu, Tomotaka Kuwahara, Keiji Saito
Understanding the ultimate rate at which information propagates is a pivotal issue in nonequilibrium physics. Nevertheless, the task of elucidating the propagation speed inherent i…
Topological Speed Limit
Tan Van Vu, Keiji Saito
Any physical system evolves at a finite speed that is constrained not only by the energetic cost but also by the topological structure of the underlying dynamics. In this Letter, b…
Effective light cone and digital quantum simulation of interacting bosons
Tomotaka Kuwahara, Tan Van Vu, Keiji Saito
The speed limit of information propagation is one of the most fundamental features in non-equilibrium physics. The region of information propagation by finite-time dynamics is appr…
