Reaching the intrinsic performance limits of superconducting nanowire single-photon detectors up to 0.1 mm wide
Kristen M. Parzuchowski, Eli Mueller, Bakhrom G. Oripov +13
Superconducting nanowire single-photon detectors (SNSPDs) combine high detection efficiency, low noise, and excellent timing resolution, making them a leading platform for photon-c…
Fast Real-Axis Eliashberg Calculations: Full-bandwidth solutions beyond the constant density of states approximation
Alejandro Simon, James Shi, Dominik Spath +10
Experimentally relevant signatures of superconductivity require access to real-frequency quantities, such as the spectral functions, optical response, and transport properties, yet…
Ultrafast dynamics and light-induced superconductivity from first principles
Alejandro Simon, James Shi, Eva Kogler +9
Experiments on superconducting materials have unveiled unique emergent properties when they are driven far from equilibrium. However, a quantitative first-principles treatment that…
Fast-Recovery Epitaxial NbN Superconducting Nanowire Single-Photon Detectors with Saturated Efficiency at 1550 nm in Liquid Helium
Francesca Incalza, Matteo Castellani, Dip Joti Paul +5
Achieving both high internal efficiency and fast reset times at elevated temperatures remains challenging due to limited understanding of how film properties govern SNSPD performan…
Ab initio modeling of nonequilibrium dynamics in superconducting detectors and qubits
Alejandro Simon, Reed Foster, Mihir Sahoo +7
Nonequilibrium quasiparticle (QP) and phonon dynamics are central to the operation of superconducting devices. Superconducting detectors, such as the superconducting nanowire singl…
Coherent control of a superconducting qubit using light
Hana K. Warner, Jeffrey Holzgrafe, Beatriz Yankelevich +15
Quantum communications technologies require a network of quantum processors connected with low loss and low noise communication channels capable of distributing entangled states. S…
