Phenomenological quantum mechanics: I. Phenomenology of quantum observables
Piotr Szańkowski, Davide Lonigro, Fattah Sakuldee +2
We propose an exercise in which one attempts to deduce the formalism of quantum mechanics solely from phenomenological observations. The only assumed inputs are obtained through se…
Universal bound on the relaxation rates for quantum Markovian dynamics
Paolo Muratore-Ginanneschi, Gen Kimura, Dariusz Chruściński
Relaxation rates provide important characteristics both for classical and quantum processes. Essentially they control how fast the system thermalizes, equilibrates, {decoheres, and…
Uncertainty relations based on state-dependent norm of commutator
Aina Mayumi, Gen Kimura, Hiromichi Ohno +1
We introduce two uncertainty relations based on the state-dependent norm of commutators, utilizing generalizations of the Böttcher-Wenzel inequality. The first relation is mathemat…
Eventually entanglement breaking divisible quantum dynamics
Krzysztof Szczygielski, Dariusz Chruściński
It is shown that a large class of quantum dynamical maps on complex matrix algebras governed by time-local Master Equations tend to become entanglement breaking in the course of ti…
Quantum versus classical -divisibility
Fabio Benatti, Dariusz Chruściński, Giovanni Nichele
-divisibility is a central concept in both classical and quantum non-Markovian processes; in particular, it is strictly related to the notion of information backflow. When restr…
Random Lindblad operators obeying detailed balance
Wojciech Tarnowski, Dariusz Chruściński, Sergey Denisov +1
We introduce different ensembles of random Lindblad operators , which satisfy quantum detailed balance condition with respect to the given stationary state of size ,…
Local generation of entanglement with Redfield dynamics
F. Benatti, D. Chruściński, R. Floreanini
In phenomenological applications, time evolutions of Bloch-Redfield type are widely adopted for modelling open system dynamics, despite their non-positive preserving character: thi…
Local numerical range for a class of hermitian operators
J. Jurkowski, A. Rutkowski, D. Chruściński
A local numerical range is analyzed for a family of circulant observables and states of composite systems. It is shown that for any circulant operator $\…
Comparative study of non-Markovianity measures in exactly solvable one and two qubit models
C. Addis, B. Bylicka, D. Chruściński +1
In this paper we present a detailed critical study of several recently proposed non-Markovianity measures. We analyse their properties for single qubit and two-qubit systems in bot…
On separable decompositions of quantum states with strong positive partial transposes
Bogna Bylicka, Dariusz Chruściński, Jacek Jurkowski
We analyze a class of positive partial transpose states (PPT) such that the positivity of its partial transposition is recognized with respect to canonical factorization of the ori…
