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…
Universal bounds on the performance of information-thermodynamic engine
Tomohiro Tanogami, Tan Van Vu, Keiji Saito
We investigate fundamental limits on the performance of information processing systems from the perspective of information thermodynamics. We first extend the thermodynamic uncerta…
Dissipation, quantum coherence, and asymmetry of finite-time cross-correlations
Tan Van Vu, Van Tuan Vo, Keiji Saito
Recent studies have revealed a deep connection between the asymmetry of cross-correlations and thermodynamic quantities in the short-time limit. In this study, we address the finit…
Geometric characterization for cyclic heat engines far from equilibrium
Tan Van Vu, Keiji Saito
Considerable attention has been devoted to microscopic heat engines in both theoretical and experimental aspects. Notably, the fundamental limits pertaining to power and efficiency…
