Low random duty-cycle errors in periodically-poled KTP revealed by sum-frequency generation
Felix Mann, Helen M. Chrzanowski, Sven Ramelow
Low-noise quantum frequency conversion in periodically-poled nonlinear crystals has proved challenging when the pump wavelength is shorter than the target wavelength. This is - at…
An efficient, tunable, and robust source of narrow-band photon pairs at the Rb D1 line
Roberto Mottola, Gianni Buser, Chris Müller +6
We present an efficient and robust source of photons at the Rb D1-line (795 nm) with a narrow bandwidth of MHz. The source is based on non-degenerate, cavity-enha…
Ultra-broadband SPDC for spectrally far separated photon pairs
Aron Vanselow, Paul Kaufmann, Helen M. Chrzanowski +1
Generating photon pairs via spontaneous parametric down-conversion (SPDC) in nonlinear crystals is important for a wide range of quantum optics experiments with spectral properties…
Experimental access to higher-dimensional entangled quantum systems using integrated optics
Christoph Schaeff, Robert Polster, Marcus Huber +2
Integrated optics allow the generation and control of increasingly complex photonic states on chip based architectures. Here, we implement two entangled qutrits - a 9-dimensional q…
Quantum orbital angular momentum of elliptically-symmetric light
William N. Plick, Mario Krenn, Robert Fickler +2
We present a quantum mechanical analysis of the orbital angular momentum of a class of recently discovered elliptically-symmetric stable light fields --- the so-called Ince-Gauss m…
Experimental non-classicality of an indivisible quantum system
Radek Lapkiewicz, Peizhe Li, Christoph Schaeff +4
Quantum theory demands that, in contrast to classical physics, not all properties can be simultaneously well defined. The Heisenberg Uncertainty Principle is a manifestation of thi…
