Time-frequency quantum process tomography of parametric down-conversion
Malte Avenhaus, Benjamin Brecht, Kaisa Laiho +1
Parametric down-conversion (PDC) is the established standard for the practical generation of a multiplicity of quantum optical states. These include two-mode squeezed vacuum, heral…
Probing spectral-temporal correlations with a versatile integrated source of parametric down-conversion states
Vahid Ansari, Benjamin Brecht, Georg Harder +1
The spectral-temporal correlation and the correlation time of a biphoton wavepacket generated in the process of parametric down-conversion (PDC), is of great importance for a broad…
Demonstration of coherent time-frequency Schmidt mode selection using dispersion-engineered frequency conversion
Benjamin Brecht, Andreas Eckstein, Raimund Ricken +4
Time-frequency Schmidt (TFS) modes of ultrafast quantum states are naturally compatible with high bit-rate integrated quantum communication networks. Thus they offer an attractive…
Bright Integrated Photon-Pair Source for Practical Passive Decoy-State Quantum Key Distribution
Stephan Krapick, Michael Stefszky, Michal Jachura +3
We report on a bright, nondegenerate type-I parametric down-conversion source, which is well suited for passive decoy-state quantum key distribution. We show the photon-number-reso…
