Photons Walking the Line: A quantum walk with adjustable coin operations
A. Schreiber, K. N. Cassemiro, V. Potocek +5
We present the first robust implementation of a coined quantum walk over five steps using only passive optical elements. By employing a fiber network loop we keep the amount of req…
Direct Measurement of the Spatial-Spectral Structure of Waveguided Parametric Down-Conversion
Peter J. Mosley, Andreas Christ, Andreas Eckstein +1
We present a study of the propagation of higher-order spatial modes in a waveguided parametric down-conversion photon pair source. Observing the multimode photon pair spectrum from…
Bridging Visible and Telecom Wavelengths with a Single-Mode Broadband Photon Pair Source
Christoph Söller, Benjamin Brecht, Peter J. Mosley +5
We present a spectrally decorrelated photon pair source bridging the visible and telecom wavelength regions. Tailored design and fabrication of a solid-core photonic crystal fiber…
Absolute efficiency estimation of photon-number-resolving detectors using twin beams
A. P. Worsley, H. B. Coldenstrodt-Ronge, J. S. Lundeen +5
A nonclassical light source is used to demonstrate experimentally the absolute efficiency calibration of a photon-number-resolving detector. The photon-pair detector calibration me…
Spatial modes in waveguided parametric down-conversion
Andreas Christ, Kaisa Laiho, Andreas Eckstein +3
The propagation of several spatial modes has a significant impact on the structure of the emission from parametric down-conversion in a nonlinear waveguide. This manifests itself n…
Pure single photon generation by type-I PDC with backward-wave amplification
A. Christ, A. Eckstein, P. J. Mosley +1
We explore a promising method of generating pure heralded single photons. Our approach is based on parametric downconversion in a periodically-poled waveguide. However, unlike conv…
