ABSTRACT We develop a unified mathematical framework extending classical moment theory from discrete integer orders to a continuous spectrum of real orders f>0$$ f>0 $$, providing a systematic statistical characterization of complex systems exhibiting power‐law behavior.

Quantum regression theorem and non-Markovianity of quantum dynamics [PDF]
We explore the connection between two recently introduced notions of non-Markovian quantum dynamics and the validity of the so-called quantum regression theorem. While non-Markovianity of a quantum dynamics has been defined looking at the behaviour in time of the statistical operator, which determines the evolution of mean values, the quantum ...

Quantum limit for driven linear non-Markovian open-quantum-systems
The interplay between non-Markovian dynamics and driving fields in the survival of entanglement between two non-degenerate oscillators is considered here.

Thermodynamics of quantum-jump trajectories of open quantum systems subject to stochastic resetting
We consider Markovian open quantum systems subject to stochastic resetting, which means that the dissipative time evolution is reset at randomly distributed times to the initial state.

Entanglement of A Qubit‐Qutrit System: Impact of Ohmic Noise
ABSTRACT This research examines the dynamics of quantum correlations in a hybrid qubit–qutrit system subjected to an Ohmic noisy environment. While entanglement degradation in homogeneous systems is well‐documented, the behavior of disparate‐dimensional interfaces remains a critical challenge for the interoperability of future quantum networks.

Comment on “General Non-Markovian Dynamics of Open Quantum Systems” [PDF]
The existence of a "non-Markovian dissipationless" regime, characterized by long lived oscillations, was recently reported for a class of quantum open systems (Zhang et al, PRL, 109, 170402, (2012)). It is claimed this could happen in the strong coupling regime, a surprising result which has attracted some attention.

Quantum nonunital dynamics of spin-bath-assisted Fisher information
The nonunital non-Markovian dynamics of qubits immersed in a spin bath is studied without any Markovian approximation. The environmental effects on the precisions of quantum parameter estimation are taken into account.

Simulation of open-quantum-system dynamics using the quantum Zeno effect
We suggest a quantum simulator that allows to study the role of memory effects in the dynamics of open quantum systems. A particular feature of our simulator is the ability to engineer both Markovian and non-Markovian dynamics by means of quantum ...

Non‐Markovianity Benefits Quantum Dynamics Simulation
ABSTRACT Quantum dynamics simulation on analog quantum simulators and digital quantum computers has emerged as a powerful and promising tool for understanding complex non‐equilibrium physics. However, the impact of quantum noise on quantum dynamics simulation, particularly non‐Markovian noise with memory effects, has remained elusive.
