Simulating generic single-qubit open-dynamics via polarization-frequency coupling in a photonic interferometer
Kalle Raikisto, Alberto Ferrara, Tom Kuusela +2
We propose a photonic platform for simulating arbitrary single-qubit open-system dynamics using a single photon in an open Mach-Zehnder interferometer. A birefringent quartz plate…
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…
Quantum jump unravelings for non-Markovian open system dynamics: a review
Federico Settimo, Jyrki Piilo
Stochastic unravelings provide a useful way to represent open quantum system dynamics in terms of pure state realizations, and have been widely studied both from a fundamental and…
Stochastic unravelings for Heisenberg picture and trace-nonpreserving dynamics
Federico Settimo, Kimmo Luoma, Dariusz ChruÅciÅski +3
Stochastic unravelings allow to efficiently simulate open system dynamics, yet their application has traditionally been restricted to master equations that preserve both Hermiticit…
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…
