Temporal nonclassicality in continuous-time quantum walks
Paolo Luppi, Claudia Benedetti, Andrea Smirne
We investigate the genuinely quantum features of continuous-time quantum walks by combining a single-time and a multi-time quantifier of nonclassicality. On the one hand, we consid…
Stochastic unravelings for Heisenberg picture and trace-nonpreserving dynamics
Federico Settimo, Kimmo Luoma, Dariusz Chruściński +3
Stochastic unravelings allow to efficiently simulate open system dynamics, yet their application has traditionally been restricted to master equations that preserve both Hermiticit…
Local energy assignment for two interacting quantum thermal reservoirs
Alessandra Colla, Bassano Vacchini, Andrea Smirne
Understanding how to assign internal energy, heat, and work in quantum systems beyond weak coupling remains a central problem in quantum thermodynamics, particularly as the differe…
Tunneling of bosonic qubits under local dephasing through microscopic approach
Alberto Ferrara, Farzam Nosrati, Andrea Smirne +2
We present a microscopic derivation of a master equation for two-component bosons (bosonic qubits) which tunnel between spatially separated modes under local dephasing noise. Start…
Quantum contextuality from measurement invasiveness
Andrea Navoni, Marco G. Genoni, Andrea Smirne
Contextuality is a defining feature that separates the quantum from the classical descriptions of physical systems. Within the marginal-scenario framework, noncontextual models are…
Classical pair of states as optimal pair for quantum distinguishability quantifiers
Bassano Vacchini, Andrea Smirne, Nina Megier
The capability to quantitatively distinguish quantum states is of great importance for a variety of tasks, and has recently played an important role in the study of quantum reduced…
Divisibility of dynamical maps: Schrödinger vs. Heisenberg picture
Federico Settimo, Andrea Smirne, Kimmo Luoma +3
Divisibility of dynamical maps is a central notion in the study of quantum non-Markovianity, providing a natural framework to characterize memory effects via time-local master equa…
Performance of rotation-symmetric bosonic codes in the presence of random telegraph noise
Adithi Udupa, Timo Hillmann, Rabsan Galib Ahmed +2
Decoherence in quantum devices, such as qubits and resonators, is often caused by bistable fluctuators modeled as random telegraph noise (RTN), leading to significant dephasing. We…
Dynamics of Open Quantum Systems with Initial System-Environment Correlations via Stochastic Unravelings
Federico Settimo, Kimmo Luoma, Dariusz Chruściński +3
In standard treatments of open quantum systems, the reduced dynamics is described starting from the assumption that the system and the environment are initially uncorrelated. This…
