(author), Zwiller, Val (author)Future quantum optical networks will require an integrated solution to multiplex suitable sources and detectors on a low-loss platform. Here we combined superconducting single-photon detectors with colloidal PbS/CdS quantum dots (QDs) and low-loss silicon nitride passive photonic components to show their combined operation at cryogenic...conference paper 2020

(author), Dorenbos, S.N. (author), Zwiller, And V.A.L. (author)Integration of superconducting nanowire single-photon detectors and quantum sources with photonic waveguides is crucial for realizing advanced quantum integrated circuits. However, scalability is hindered by stringent requirements on high-performance detectors. Here we overcome the yield limitation by controlled coupling of photonic channels...journal article 2019

(author), Zwiller, Val (author), Esmaeil Zadeh, I.Z. (author)We experimentally investigate the performance of NbTiN superconducting nanowire single photon detectors above the base temperature of a conventional Gifford-McMahon cryocooler (2.5 K). By tailoring design and thickness (8 - 13 nm) of the detectors, high performance, high operating temperature, single-photon detection from the visible to...journal article 2019

(author), Zwiller, V.G. (author)Single-photon sources and detectors are indispensable building blocks for integrated quantum photonics, a research field that is seeing ever increasing interest for numerous applications. In this work, we implemented essential components for a quantum key distribution transceiver on a single photonic chip. Plasmonic antennas on top of silicon...journal article 2019

Redaelli, L. (author), Bulgarini, G. (author), Dobrovolskiy, S. (author), Dorenbos, S. N. (author), Zwiller, V.G. (author), Monroy, E (author), Gerard, J.A. (author)In this paper several designs to maximize the absorption efficiency of superconducting-nanowire single-photon detectors are investigated. Using a simple optical cavity consisting of a gold mirror and a SiO<sub>2</sub> layer, the absorption efficiency can be boosted to over 97%: this result is confirmed experimentally by the realization of an...journal article 2016
