Statistically significant tests of multiparticle quantum correlations based on randomized measurements
Andreas Ketterer, Satoya Imai, Nikolai Wyderka +1
We consider statistical methods based on finite samples of locally randomized measurements in order to certify different degrees of multiparticle entanglement in intermediate-scale…
In-situ ac Stark shift Detection in Light Storage Spectroscopy
Deviprasath Palani, Daniel Hoenig, Leon Karpa
We report on a method for measuring ac Stark shifts observed in stored light experiments while simultaneously determining the energetic splitting between the electronic ground stat…
Bound entanglement from randomized measurements
Satoya Imai, Nikolai Wyderka, Andreas Ketterer +1
If only limited control over a multiparticle quantum system is available, a viable method to characterize correlations is to perform random measurements and consider the moments of…
Simulation of wave-particle duality in multi-path interferometers on a quantum computer
Mirko Amico, Christoph Dittel
We present an architecture to investigate wave-particle duality in -path interferometers on a universal quantum computer involving as low as qubits and develop a measu…
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…
Superradiance from non-ideal initial states -- a quantum trajectory approach
Sebastian Fuchs, András Vukics, Stefan Yoshi Buhmann
Collective emission behavior is usually described by the decay dynamics of the completely symmetric Dicke states. To study a more realistic scenario, we investigate alternative ini…
Open quantum systems decay across time
Juliane Klatt, Chahan Michael Kropf, Stefan Yoshi Buhmann
The description of an open quantum system's decay almost always requires several approximations as to remain tractable. Here, we first revisit the meaning, domain and seeming contr…
Many-body interference in bosonic dynamics
Gabriel Dufour, Tobias Brünner, Alberto Rodríguez +1
We develop a framework to systematically investigate the influence of many-particle interference on the dynamics of generic possibly interacting bosonic systems. We conside…
Non-Hermitian and Zeno limit of quantum systems under rapid measurements
Felix Thiel, David A. Kessler
We investigate in depth the relation between the first detection time of an isolated quantum system that is repeatedly perturbed by strong local measurements with a large fixed fre…
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…
Continuously parametrized quantum simulation of molecular electron transfer reactions
Frank Schlawin, Manuel Gessner, Andreas Buchleitner +2
A comprehensive description of molecular electron transfer reactions is essential for our understanding of fundamental phenomena in bio-energetics and molecular electronics. Experi…
Complementarity between one- and two-body visibilities
Christoph Dittel, Gregor Weihs
We study one- and two-body visibility measures under an optimization of common, i.e. global evolutions of a two-body system, and identify two different visibilities of two-body cor…
Entanglement Production and Convergence Properties of the Variational Quantum Eigensolver
Andreas J. C. Woitzik, Panagiotis Kl. Barkoutsos, Filip Wudarski +2
We perform a systematic investigation of variational forms (wave function Ansätze), to determine the ground state energies and properties of two-dimensional model fermionic systems…
Quantum probing beyond pure dephasing
Dario Tamascelli, Claudia Benedetti, Heinz-Peter Breuer +1
Quantum probing is the art of exploiting simple quantum systems interacting with a complex environment to extract precise information about some environmental parameters, e.g. the…
Spectral Structure and Many-Body Dynamics of Ultracold Bosons in a Double-Well
Frank Schäfer, Miguel A. Bastarrachea-Magnani, Axel U. J. Lode +2
We examine the spectral structure and many-body dynamics of two and three repulsively interacting bosons trapped in a one-dimensional double-well, for variable barrier height, inte…
Non-interacting many-particle quantum transport between finite reservoirs
Giulio Amato, Heinz-Peter Breuer, Sandro Wimberger +2
We present a formalism to study many-particle quantum transport across a lattice locally connected to two finite, non-stationary (bosonic or fermionic) reservoirs, both of which ar…
