Open system model for quantum dynamical maps with classical noise and corresponding master equations
Chahan M. Kropf, Vyacheslav N. Shatokhin, Andreas Buchleitner
We show how random unitary dynamics arise from the coupling of an open quantum system to a static environment. Subsequently, we derive a master equation for the reduced system rand…
Diffraction-induced entanglement loss of orbital-angular-momentum states
Giacomo Sorelli, Vyacheslav N. Shatokhin, Filippus S. Roux +1
We provide an analytical expression for the entanglement decay of initially maximally entangled orbital angular momentum bi-photon states, when scattered off an obstruction. We sho…
Signatures of indistinguishability in bosonic many-body dynamics
Tobias Brünner, Gabriel Dufour, Alberto Rodríguez +1
The dynamics of bosons in generic multimode systems, such as Bose-Hubbard models, is not only determined by interactions among the particles, but also by their mutual indistinguish…
Protecting entanglement of twisted photons by adaptive optics
Nina Leonhard, Giacomo Sorelli, Vyacheslav N. Shatokhin +2
We study the efficiency of adaptive optics (AO) correction for the free-space propagation of entangled photonic orbital-angular-momentum (OAM) qubit states, to reverse moderate atm…
Many-particle interference in a two-component bosonic Josephson junction: an all-optical simulation
Gabriel Dufour, Tobias Brünner, Christoph Dittel +3
We conceive an all-optical representation of the dynamics of two distinct types of interacting bosons in a double well by an array of evanescently coupled photonic waveguides. Many…
Scattering Theory of Efficient Quantum Transport across Finite Networks
Mattia Walschaers, Roberto Mulet, Andreas Buchleitner
We present a scattering theory for the efficient transmission of an excitation across a finite network with designed disorder. We show that the presence of randomly positioned netw…
