Microwave Photon Detectors for Superconducting Qubit Readout<\/strong><\/p>\n\n\n\n The ability to detect individual microwave photons is a key enabling technology for quantum computing, quantum sensing, and fundamental physics experiments. Despite recent breakthroughs in detection efficiency, existing single-photon detectors typically suffer from a limited dynamic range, making them unsuitable for measuring signals containing more than a few photons. Overcoming this limitation by developing detectors sensitive to microwave pulses spanning 1 to 100 photons<\/strong> would represent a major step forward, particularly towards single-shot readout of superconducting qubits without the need for parametric amplifiers<\/strong>.<\/p>\n\n\n\n Our group has recently demonstrated a novel approach to microwave photon detection based on a microwave photon-to-electron converter<\/strong>, in which a superconducting tunnel junction acts as a voltage-tunable quantum absorber through photon-assisted quasiparticle tunneling [1,2]. By developing an ultrasensitive charge detection technique, we have further demonstrated the detection of individual microwave photons [3].<\/p>\n\n\n\n We are seeking an enthusiastic student to contribute to the design, nanofabrication, and experimental characterization of this new detector<\/strong>. The student will work closely with permanent researchers and gain hands-on experience in superconducting circuits, electron-beam lithography, metal deposition, and ultrasensitive measurements in a dilution refrigerator operating at 20 mK<\/strong>.<\/p>\n\n\n\n Beyond advancing fundamental research, this project opens promising perspectives for quantum computing and sensing<\/strong>, offering the student an opportunity to develop experimental skills at the forefront of quantum technologies.<\/p>\n\n\n\n [1] Aiello et al, Quantum bath engineering of a high impedance microwave mode through quasiparticle tunnelling,<\/em> Nature Communications 13, 7146 (2022)<\/a>. https:\/\/www.iledefrance-gif.cnrs.fr\/fr\/cnrsinfo\/de-leffet-photoelectrique-aux-technologies-quantiques<\/a><\/p>\n\n\n\n [2] Stanisavljevic et al, Efficient Microwave Photon-to-Electron Conversion in a High-Impedance Quantum Circuit<\/em>, Physical Review Letters 133, 076302 (2024)<\/a>. https:\/\/physics.aps.org\/articles\/v17\/127<\/a><\/p>\n\n\n\n [3] Basset et al, Fast and Continuous Detection of Single Microwave Photons via Photoassisted Quasiparticle Tunneling to a Superconducting Island Physical Review Letters 136, 237001 (2026)<\/a><\/p>\n\n\n\n Contact J\u00e9r\u00f4me ESTEVE <\/strong>(jerome.esteve@universite-paris-saclay.fr) and\/or Julien BASSET<\/strong> (julien.basset@universite-paris-saclay.fr)<\/p>\n\n\n\n Other internships\/jobs at the LPS<\/a>.
