Journal ArticleDOI
Gaussian Boson Sampling.
TL;DR: The protocol for Gaussian Boson Sampling with single-mode squeezed states is presented and it is shown that the proposal with the Hafnian matrix function can retain the higher photon number contributions at the input.
Journal ArticleDOI
First experimental realization of the Dirac oscillator
John-Alexander Franco-Villafañe,Emerson Sadurni,Sonja Barkhofen,Ulrich Kuhl,Fabrice Mortessagne,Thomas H. Seligman +5 more
TL;DR: The first experimental microwave realization of the one-dimensional Dirac oscillator is presented, a paradigm in exactly solvable relativistic systems, and the flexibility of the experimental setup allows the implementation of other one- dimensional Dirac-type equations.
Journal ArticleDOI
Detailed study of Gaussian boson sampling
TL;DR: In this paper, the authors derive an expression that relates the probability to measure a specific photon output pattern from a Gaussian state to the Hafnian matrix function and use it to design a new Gaussian boson sampling protocol.
Proceedings ArticleDOI
Gaussian Boson sampling
TL;DR: In this article, the authors present a Gaussian Boson sampling protocol with single-mode squeezed states, which eliminates heralding and shows that the Hafnian matrix function can retain the higher photon number contributions at the input.
Journal ArticleDOI
Measuring topological invariants in disordered discrete-time quantum walks
Sonja Barkhofen,Thomas Nitsche,Fabian Elster,Lennart Lorz,Aurél Gábris,Aurél Gábris,Igor Jex,Christine Silberhorn +7 more
TL;DR: In this article, the authors implemented the scattering scheme proposed by Tarasinski et al. in a photonic time multiplexed quantum walk experiment to directly measure the topological invariants of quantum walks.
