Quantum speed limit in terms of coherence variations

Z Mai, C Yu - Physical Review A, 2024 - APS
Coherence is the most fundamental quantum resource in quantum information processing.
How fast a physical system gets coherence or decoherence is a critical ingredient. We …

Exact quantum speed limits

AK Pati, B Mohan, SL Braunstein - arxiv preprint arxiv:2305.03839, 2023 - arxiv.org
The traditional quantum speed limits are not attainable for many physical processes, as they
tend to be loose and fail to determine the exact time taken by quantum systems to evolve. To …

Finite-Time Processes In Quantum Thermodynamics: The Limits Of Irreversibility

A Rolandi - arxiv preprint arxiv:2410.18903, 2024 - arxiv.org
The emergence of irreversibility in physical processes, despite the fundamentally reversible
nature of quantum mechanics, remains an open question in physics. This thesis explores the …

Generalized geometric speed limits for quantum observables
