Direct measurement of second-order coupling in a waveguide lattice
Robert Keil, Benedikt Pressl, René Heilmann +3
We measure the next-nearest-neighbour coupling in an array of coupled optical waveguides directly via an integrated eigenmode interferometer. In contrast to light propagation exper…
Implementation of Quantum and Classical Discrete Fractional Fourier Transforms
Steffen Weimann, Armando Perez-Leija, Maxime Lebugle +9
Fourier transforms are ubiquitous mathematical tools in basic and applied sciences. We here report classical and quantum optical realizations of the discrete fractional Fourier tra…
Enhancing quantum transport in a photonic network using controllable decoherence
Devon N. Biggerstaff, René Heilmann, Aidan A. Zecevik +7
Transport phenomena on a quantum scale appear in a variety of systems, ranging from photosynthetic complexes to engineered quantum devices. It has been predicted that the efficienc…
Divide-and-Conquer: An integrated photon-counting scheme
Rene Heilmann, Jan Sperling, Armando Perez-Leija +5
The key requirement for harnessing the quantum properties of light is the capability to detect and count individual photons. Of particular interest are photon-number-resolving dete…
Bloch Oscillations of Einstein-Podolsky-Rosen States
Maxime Lebugle, Markus Gräfe, René Heilmann +3
Bloch Oscillations (BOs) of quantum particles manifest themselves as periodic spreading and re-localization of the associated wave functions when traversing lattice potentials subj…
