Non-Markovianity of Quantum Brownian Motion
Simon Einsiedler, Andreas Ketterer, Heinz-Peter Breuer
We study quantum non-Markovian dynamics of the Caldeira-Leggett model, a prototypical model for quantum Brownian motion describing a harmonic oscillator linearly coupled to a reser…

Entanglement characterization using quantum designs
Andreas Ketterer, Nikolai Wyderka, Otfried Gühne
We present in detail a statistical approach for the reference-frame-independent detection and characterization of multipartite entanglement based on moments of randomly measured co…
