Lossy SU(1,1) interferometers in the single-photon-pair regime
Matteo Santandrea, Kai-Hong Luo, Michael Stefszky +3
The success of quantum technologies is intimately connected to the possibility of using them in real-world applications. To this aim, we study the sensing capabilities of quantum S…
Quantum optical coherence: From linear to nonlinear interferometers
K. -H. Luo, M. Santandrea, M. Stefszky +6
Interferometers provide a highly sensitive means to investigate and exploit the coherence properties of light in metrology applications. However, interferometers come in various fo…
Spectrally multimode integrated SU(1,1) interferometer
Alessandro Ferreri, Matteo Santandrea, Michael Stefszky +4
Nonlinear SU(1,1) interferometers are fruitful and promising tools for spectral engineering and precise measurements with phase sensitivity below the classical bound. Such interfer…
Counter-propagating photon pair generation in a nonlinear waveguide
Kai-Hong Luo, Vahid Ansari, Marcello Massaro +5
Counter-propagating parametric conversion processes in non-linear bulk crystals have been shown to feature unique properties for efficient narrowband frequency conversion. In quant…
Nonlinear integrated quantum electro-optic circuits
Kai-Hong Luo, Sebastian Brauner, Christof Eigner +5
Future quantum computation and networks require scalable monolithic circuits, which incorporate various advanced functionalities on a single physical substrate. Although substantia…
Quantum frequency conversion between infrared and ultraviolet
Helge Rütz, Kai-Hong Luo, Hubertus Suche Christine Silberhorn
We report on the implementation of quantum frequency conversion (QFC) between infrared (IR) and ultraviolet (UV) wavelengths by using single-stage upconversion in a periodically po…
