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…
