Chang, J. (author), Gao, Jun (author), Esmaeil Zadeh, I.Z. (author), Elshaari, Ali W. (author), Zwiller, Val (author)At the core of quantum photonic information processing and sensing, two major building pillars are single-photon emitters and single-photon detectors. In this review, we systematically summarize the working theory, material platform, fabrication process, and game-changing applications enabled by state-of-the-art quantum dots in nanowire...review 2023

(author), Vinke, Peter (author), Quintero Perez, M. (author), Heedt, S. (author), Kouwenhoven, Leo P. (author)In superconducting quantum circuits, aluminum is one of the most widely used materials. It is currently also the superconductor of choice for the development of topological qubits. However, aluminum-based devices suffer from poor magnetic field compatibility. Herein, this limitation is resolved by showing that adatoms of heavy elements (e.g.,...journal article 2022

(author)We study the effect of external electric fields on superconductor-semiconductor coupling by measuring the electron transport in InSb semiconductor nanowires coupled to an epitaxially grown Al superconductor. We find that the gate voltage induced electric fields can greatly modify the coupling strength, which has consequences for the proximity...journal article 2018

Marsili, F. (author), Najafi, F. (author), Herder, C. (author), Berggren, K.K. (author)We developed an electrothermal model of NbN superconducting nanowire avalanche photodetectors (SNAPs) on sapphire substrates. SNAPs are single-photon detectors consisting of the parallel connection of N superconducting nanowires. We extrapolated the physical constants of the model from experimental data and we simulated the time evolution of the...journal article 2011

(author)We report the detection of single electrons using a Nb0.7Ti0.3N superconducting wire deposited on an oxidized silicon substrate. While it is known that this device is sensitive to single photons, we show that it also detects single electrons with kilo-electron-volt energy emitted from the cathode of a scanning electron microscope with an...journal article 2010

(author), Dorenbos, S.N. (author), Bermúdez Ureña, E. (author), Zijlstra, T. (author), Klapwijk, T.M. (author), Zwiller, V. (author)Superconducting nanowire single-photon detectors (SNSPDs) have emerged as a highly promising infrared single-photon detector technology. Next-generation devices are being developed with enhanced detection efficiency (DE) at key technological wavelengths via the use of optical cavities. Furthermore, new materials and substrates are being explored...journal article 2010
