Initial correlations in open system's dynamics: The Jaynes-Cummings model
A. Smirne, H. -P. Breuer, J. Piilo +1
Employing the trace distance as a measure for the distinguishability of quantum states, we study the influence of initial correlations on the dynamics of open systems. We concentra…
Counting Statistics of Many-Particle Quantum Walks
Klaus Mayer, Malte C. Tichy, Florian Mintert +2
We study quantum walks of many non-interacting particles on a beam splitter array, as a paradigmatic testing ground for the competition of single- and many-particle interference in…
Four-Photon (In)Distinguishability Transition
Malte C. Tichy, Hyang-Tag Lim, Young-Sik Ra +3
We demonstrate the conspiration of many-particle interferences of different degree to determine the transmission of four photons of tunable indistinguishability through a four-port…
Entanglement dynamics in open two-qubit systems via diffusive quantum trajectories
Carlos Viviescas, Ivonne Guevara, André R. R. Carvalho +2
We use quantum diffusive trajectories to prove that the time evolution of two-qubit entanglement under spontaneous emission can be fully characterized by optimal continuous monitor…
Stochastic simulation algorithm for the quantum linear Boltzmann equation
Marc Busse, Piotr Pietrulewicz, Heinz-Peter Breuer +1
We develop a Monte Carlo wave function algorithm for the quantum linear Boltzmann equation, a Markovian master equation describing the quantum motion of a test particle interacting…
Witness for initial system-environment correlations in open system dynamics
Elsi-Mari Laine, Jyrki Piilo, Heinz-Peter Breuer
We study the evolution of a general open quantum system when the system and its environment are initially correlated. We show that the trace distance between two states of the open…
