A high-performance quantum pulse gate in thin-film lithium niobate
Silia Babel, Alejandra Alarcón, Laura Serino +10
In this work, we demonstrate a quantum pulse gate (QPG) in thin-film lithium niobate. QPGs enable the selective manipulation and detection of temporal modes of quantum light and fo…
Widely non-degenerate nonlinear frequency conversion in cryogenic titanium in-diffused lithium niobate waveguides
Nina Amelie Lange, Sebastian Lengeling, Philipp Mues +6
The titanium in-diffused lithium niobate waveguide platform is well-established for reliable prototyping and packaging of many quantum photonic components at room temperature. Neve…
Towards integrated sensors for optimized OCT with undetected photons
Franz Roeder, René Pollmann, Viktor Quiring +3
The development of practical sensors for optical coherence tomography (OCT) with undetected photons requires miniaturization via integration. To be practical, these sensors must ex…
A ultrabright, two-colour photon pair source based on thin-film lithium niobate for bridging visible and telecom wavelengths
Silia Babel, Laura Bollmers, Franz Roeder +9
We present the design and characterisation of a guided-wave, bright and highly frequency non-degenerate parametric down-conversion source in thin-film lithium niobate. The source g…
Cryogenic Feedforward of a Photonic Quantum State
Frederik Thiele, Niklas Lamberty, Thomas Hummel +8
Modulation conditioned on measurements on entangled photonic quantum states is a cornerstone technology of optical quantum information processing. Performing this task with low lat…
Programmable time-frequency mode-sorting of single photons with a multi-output quantum pulse gate
Laura Serino, Christof Eigner, Benjamin Brecht +1
We demonstrate a high-dimensional mode-sorter for single photons based on a multi-output quantum pulse gate, which we can program to switch between different temporal-mode encoding…
