Jad Benserhir<\/span><\/span>, The School of Applied and Engineering Physics Seminar Series will occur on Thursday 17 th April<\/b>, at 15:30 <\/b>at the UM6P campus (Ryad 5, 1st floor<\/strong>).<\/p>\n Abstract:<\/span><\/b><\/span><\/p>\n Scaling up quantum technologies requires reliable and low-noise electronic interfaces between quantum devices operating at cryogenic temperatures and room-temperature systems. In this work, we explore the use of industrial BiCMOS technologies to meet this challenge, focusing on both quantum computing and superconducting nanowire detector (SNWD) arrays. We present a detailed noise characterization of advanced SiGe heterojunction bipolar transistors (HBTs) down to 4 K and up to 12 GHz, revealing their potential for low-power, high-fidelity cryogenic signal processing. Building on this, we demonstrate a low-noise amplifier operating at 4 K with an 8 GHz bandwidth and just 5 mW of power. We also introduce novel readout strategies for SNWDs using their intrinsic latching behavior and propose a cryogenic superheterodyne transmitter with a phase-locked loop for scalable qubit control. These results offer practical pathways to integrate quantum sensors and processors with classical control systems in future large-scale quantum platforms.<\/span><\/p>\n<\/div>\n Biography<\/span><\/b><\/span>:<\/span> Jad Benserhir received the B.Sc. degree in engineering physics from the Institut National Polytechnique de Grenoble (INPG), France, in 2017, and the triple joint M.Sc. degree in micro and nanotechnologies for integrated systems from the Politecnico di Torino, Italy, the Institut National Polytechnique de Grenoble (INPG) , France, and the \u00c9cole Polytechnique F\u00e9d\u00e9rale de Lausanne (EPFL), Switzerland, in 2019. He completed his Ph.D. in 2024 at the Advanced Quantum Architecture Laboratory (AQUA) at EPFL, where he focused on CMOS\/BiCMOS circuits for superconductive nanowire single-photon detectors (SNSPDs) front-end design and quantum applications. He was also a Research Assistant at the City University of Hong Kong in 2018. Jad has joined the Quantum & Computing Engineering Department of Delft University of Technology in Netherlands as a postdoctoral researcher to continue his work on superconductive nanowire single-photon detectors and their applications in quantum technologies.<\/span><\/p>\n
