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 …

Objectivity of classical quantum stochastic processes

P Szańkowski, Ł Cywiński - Quantum, 2024 - quantum-journal.org
We investigate what can be concluded about a quantum system when sequential quantum
measurements of its observable–a prominent example of the so-called quantum stochastic …

Classical-quantum correspondence in noise-based dissipative systems

J Zeng, GH Xu, W Huang, Y Yao - Physical Review A, 2024 - APS
We investigate the correspondence between classical noise and quantum environments.
Although it is known that classical noise can be mapped to quantum environments for pure …

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 …

Superclassical non-Markovian open quantum dynamics

AA Budini - arxiv preprint arxiv:2411.13471, 2024 - arxiv.org
We characterize a class of superclassical non-Markovian open quantum system dynamics
that are defined by their lack of measurement invasiveness when the corresponding …

Statistics of projective measurement on a quantum probe as a witness of noncommutativity of algebra of a probed system

F Sakuldee, Ł Cywiński - Quantum Information Processing, 2022 - Springer
We consider a quantum probe P undergoing pure dephasing due to its interaction with a
quantum system S. The dynamics of P is then described by a well-defined sub-algebra of …

[PDF][PDF] Nonclassical Temporal Correlations Under Finite-Memory Constraints

LV Barbosa - 2024 - phaidra.univie.ac.at
Any concrete information processing task can be viewed as the sequential manipulation of
information over time, receiving inputs and producing outputs. To accomplish this …
