Theory of filtered type-II PDC in the continuous-variable domain: Quantifying the impacts of filtering
Andreas Christ, Cosmo Lupo, Matthias Reichelt +2
Parametric down-conversion (PDC) forms one of the basic building blocks for quantum optical experiments. However, the intrinsic multimode spectral-temporal structure of pulsed PDC…
Spatio-spectral characteristics of parametric down-conversion in waveguide arrays
Regina Kruse, Fabian Katzschmann, Andreas Christ +7
High dimensional quantum states are of fundamental interest for quantum information processing. They give access to large Hilbert spaces and, in turn, enable the encoding of quantu…
Theory of quantum frequency conversion and type-II parametric down-conversion in the high-gain regime
Andreas Christ, Benjamin Brecht, Wolfgang Mauerer +1
Frequency conversion (FC) and type-II parametric down-conversion (PDC) processes serve as basic building blocks for the implementation of quantum optical experiments: type-II PDC e…
Exponentially enhanced quantum communication rate by multiplexing continuous-variable teleportation
Andreas Christ, Cosmo Lupo, Christine Silberhorn
A major challenge of today's quantum communication systems lies in the transmission of quantum information with high rates over long distances in the presence of unavoidable losses…
Limits on the deterministic creation of pure single-photon states using parametric down-conversion
Andreas Christ, Christine Silberhorn
Parametric down-conversion (PDC) is one of the most widely used methods to create pure single-photon states for quantum information applications. However little attention has been…
From quantum pulse gate to quantum pulse shaper -- enigneered frequency conversion in nonlinear optical waveguides
Benjamin Brecht, Andreas Eckstein, Andreas Christ +2
Full control over the spatio-temporal structure of quantum states of light is an important goal in quantum optics, to generate for instance single-mode quantum pulses or to encode…
