Coherent temporal filtering of multimode parametric down-conversion using a quantum pulse gate
Abhinandan Bhattacharjee, Patrick Folge, Laura Serino +3
Spectrally pure and indistinguishable single photons are essential for quantum network platforms, where high-visibility interference underpins many quantum information protocols. H…
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…
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…
