Double or nothing: a Kolmogorov extension theorem for multitime (bi)probabilities in quantum mechanics
Davide Lonigro, Fattah Sakuldee, Åukasz CywiÅski +2
The multitime probability distributions obtained by repeatedly probing a quantum system via the measurement of an observable generally violate Kolmogorov's consistency property. Th…

Generalized Rate Operator Quantum Jumps via Realization-Dependent Transformations
Federico Settimo, Kimmo Luoma, Dariusz ChruÅciÅski +3
The dynamics of open quantum systems is often solved by stochastic unravellings where the average over the state vector realizations reproduces the density matrix evolution. We foc…

A class of Schwarz qubit maps with diagonal unitary and orthogonal symmetries
Dariusz ChruÅciÅski, Bihalan Bhattacharya
A class of unital qubit maps displaying diagonal unitary and orthogonal symmetries is analyzed. Such maps already found a lot applications in quantum information theory. We provide…
