Characterising the hierarchy of multi-time quantum processes with classical memory

P Taranto, MT Quintino, M Murao, S Milz - Quantum, 2024 - quantum-journal.org
Memory is the fundamental form of temporal complexity: when present but uncontrollable, it
manifests as non-Markovian noise; conversely, if controllable, memory can be a powerful …

Process tensor distinguishability measures

G Zambon - Physical Review A, 2024 - APS
Process tensors are quantum combs describing the evolution of open quantum systems
through multiple steps of quantum dynamics. While there is more than one way to measure …

Relations between Markovian and non-Markovian correlations in multitime quantum processes

G Zambon, DO Soares-Pinto - Physical Review A, 2024 - APS
In the dynamics of open quantum systems, information may propagate in time through either
the system or the environment, giving rise to Markovian and non-Markovian temporal …

Quantum processes as thermodynamic resources: the role of non-Markovianity

G Zambon, G Adesso - arxiv preprint arxiv:2411.05559, 2024 - arxiv.org
Quantum thermodynamics studies how quantum systems and operations may be exploited
as sources of work to perform useful thermodynamic tasks. In real-world conditions, the …

Entropic witness for quantum memory in open system dynamics

C Bäcker, K Beyer, WT Strunz - arxiv preprint arxiv:2501.17660, 2025 - arxiv.org
The dynamics of open quantum system are often modeled by non-Markovian processes that
account for memory effects arising from interactions with the environment. It is well-known …
