Reduced Quantum-Reference-Frame Channels for Open Quantum Systems
Paolo Luppi, Viktoria Kabel, Flaminia Giacomini +1
When reference frames are treated quantum mechanically, the subsystem structure of quantum systems is no longer absolute, but depends on the choice of the quantum reference frame (…
Schrödinger and Heisenberg non-Markovianity in quantum information tasks
Federico Settimo, Kimmo Luoma, Jyrki Piilo +3
Quantum non-Markovianity has been widely studied and connected to the existence of memory effects in the dynamics of open systems. Surprisingly, working in the Schrödinger or in t…
Revivals of Bell nonlocality require Schrödinger and Heisenberg non-Markovianity
Federico Settimo, Kimmo Luoma, Jyrki Piilo +3
Bell nonlocality is a key resource in quantum information, demonstrating the nonclassicality of quantum theory. Noise, however, {is in general detrimental to} nonlocality, and can…
Non-Markovianity in the Adapted Caldeira-Leggett model
Luciano Manara, Andrea Smirne, Bassano Vacchini
In this work, we investigate the non-Markovian features of the Adapted Caldeira-Leggett model, a computationally efficient framework recently proposed to capture the essential phys…
Multitime memory beyond the quantum regression theorem in sequential measurement statistics
Paolo Luppi, Claudia Benedetti, Andrea Smirne
We investigate the presence of memory in the sequential measurement statistics of an open quantum system, as witnessed by the departure from the quantum regression theorem (QRT), t…
Fluctuations of path-dependent thermodynamic quantities in open quantum systems via two-point system-only measurements
Alessandra Colla, Andrea Smirne, Heinz-Peter Breuer +1
We propose a method to evaluate general thermodynamic fluctuations in open quantum systems, based on performing a two-point measurement scheme on the system using dynamics-dependen…
