Laser-lithographically written micron-wide superconducting nanowire single-photon detectors
Maximilian Protte, Varun B. Verma, Jan Philipp Höpker +3
We demonstrate the fabrication of micron-wide tungsten silicide superconducting nanowire single-photon detectors on a silicon substrate using laser lithography. We show saturated i…
Cryogenic integrated spontaneous parametric down-conversion
Nina Amelie Lange, Jan Philipp Höpker, Raimund Ricken +4
Scalable quantum photonics relies on interfacing many optical components under mutually compatible operating conditions. To that end, we demonstrate that spontaneous parametric dow…
Integrated superconducting nanowire single-photon detectors on titanium in-diffused lithium niobate waveguides
Jan Philipp Höpker, Varun B. Verma, Maximilian Protte +10
We demonstrate the integration of amorphous tungsten silicide superconducting nanowire single-photon detectors on titanium in-diffused lithium niobate waveguides. We show proof-of-…
Quantum detector tomography of a high dynamic-range superconducting nanowire single-photon detector
Timon Schapeler, Jan Philipp Hoepker, Tim J. Bartley
We demonstrate and verify quantum detector tomography of a superconducting nanowire single-photon detector (SNSPD) in a multiplexing scheme which permits measurement of up to 71000…
