Exceptional point structure and chiral state transfer in a rate-operator-engineered -symmetric Bose-Hubbard dimer
Jaakko Luomala, Federico Settimo, Kimmo Luoma +2
The rate operator quantum jumps (ROQJ) is a general method to unravel a master equation describing the dynamics of an open quantum system into stochastic pure state trajectories. B…
Engineering of Non-Hermitian Trajectories and Phase Structure in an Open Bose-Hubbard Model via Rate Operator Transformations
Jaakko Luomala, Kimmo Luoma, Iiro Vilja +1
Non-Hermitian evolution can be realized through post-selection on stochastic pure-state trajectories arising in continuously monitored open quantum systems. The rate operator forma…
Group-theoretic treatment of strong light-matter coupling with an arbitrary number of excitations
Antti Peltola, Olli Siltanen, Kimmo Luoma +1
Strong light-matter interactions in optical microcavities give rise to hybrid light-matter states known as polaritons. While actively used in modern technologies, theoretical descr…
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 th…
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 ca…
Vibrationally Induced Resonances in Lasing
Kai Müller, Kimmo Luoma, Christian Schäfer
Optical circuits and light sources, such as lasers, undergo continuous miniaturization. In its extreme, nanolasers might be comprised of only a few molecules confined in plasmonic…
