3D micro-printing: An enabling technique for arbitrary potential landscapes for photonic quantum-gases
Julian Schulz, Kirankumar Karkihalli Umesh, Sven Enns +2
Photonic quantum gases explore the physics of open driven-dissipative quantum systems under ambient conditions and thus open access to thermodynamics and transport phenomena in qua…
Polarization properties of photon Bose-Einstein condensates
Sven Enns, Julian Schulz, Kirankumar Karkihalli Umesh +2
The first experimental realization of a photon Bose-Einstein condensate was demonstrated more than a decade ago. However, the polarization of the condensate has not been fully unde…
An optical frequency shifter based on continuous-wave pump fields
Anica Hamer, Frank Vewinger, Michael H. Frosz +1
Practical implementations of quantum information networks require frequency conversion of individual photons. Approaches based on a molecular gas as the nonlinear medium cover a wi…
Frequency conversion in a hydrogen-filled hollow-core fiber: power scaling, background, and bandwidth
Anica Hamer, Frank Vewinger, Michael H. Frosz +1
Large-area quantum networks based on optical fibers allow photons at near-infrared wavelengths to travel with minimal loss. Quantum frequency conversion is a method to alter the wa…
Frequency conversion in a hydrogen-filled hollow-core fiber using continuous-wave fields
Anica Hamer, Frank Vewinger, Thorsten Peters +2
In large-area quantum networks based on optical fibers, photons are the fundamental carriers of information as so-called flying qubits. They may also serve as the interconnect betw…
