This material combination leads to spatial variations of the superconducting properties, which gives rise to Andreev bound states (ABSs). Some of these states might exhibit remarkable properties that render them highly desirable for topological quantum computing. The most prominent and hunted of such states are Majorana zero modes (MZMs), quasiparticles equals to their own quasiparticles that they follow non-abelian statistics. In this thesis, we first introduce the general framework of such hybrid systems and, then, we unveil a series of mesoscopic phenomena that we discovered. Firstly, we show tunneling spectroscopy experiments on full-shell nanowires (NWs) showing that unwanted quantum-dot states coupled to superconductors (Yu-Shiba-Rusinov states) can mimic MZMs signatures. Then, we introduce a novel protocol which allowed the integration of tunneling spectroscopy with Coulomb spectroscopy within the same device. Employing this approach on both full-shell NWs and partial-shell NWs, we demonstrated that longitudinally confined states reveal charge transport phenomenology similar to the one expected for MZMs. These findings shed light on the intricate interplay between superconductivity and quantum confinement, which brought us to explore another material platform, i.e. a two-dimensional Germanium hole gas. After developing a robust way to induce superconductivity in such system, we showed how to engineer the proximity effect and we revealed a superconducting hard gap. Finally, we created a superconducting radio frequency driven ideal diode and a generator of non-sinusoidal current-phase relations. Our results open the path for the exploration of protected superconducting qubits and more complex hybrid devices in planar Germanium, like Kitaev chains and hybrid qubit devices.","lang":"eng"}],"language":[{"iso":"eng"}],"has_accepted_license":"1","project":[{"_id":"262116AA-B435-11E9-9278-68D0E5697425","name":"Hybrid Semiconductor - Superconductor Quantum Devices"},{"call_identifier":"H2020","_id":"237E5020-32DE-11EA-91FC-C7463DDC885E","name":"TOPOLOGICALLY PROTECTED AND SCALABLE QUANTUM BITS","grant_number":"862046"},{"grant_number":"F8606","name":"Conventional and unconventional topological superconductors","_id":"34a66131-11ca-11ed-8bc3-a31681c6b03e"}],"acknowledged_ssus":[{"_id":"NanoFab"},{"_id":"M-Shop"}],"oa_version":"Published Version","month":"07","file":[{"date_created":"2023-08-11T09:27:39Z","file_size":56121429,"checksum":"666ee31c7eade89679806287c062fa14","date_updated":"2023-08-11T10:01:34Z","file_name":"PhD_thesis_Valentini_final.zip","content_type":"application/x-zip-compressed","relation":"source_file","access_level":"closed","file_id":"14033","creator":"mvalenti"},{"creator":"mvalenti","file_id":"14035","relation":"main_file","access_level":"open_access","file_name":"PhD_thesis_Valentini_final_validated.pdf","content_type":"application/pdf","date_updated":"2023-08-11T14:39:17Z","file_size":38199711,"checksum":"0992f2ebef152dee8e70055350ebbb55","date_created":"2023-08-11T14:39:17Z"}],"user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","related_material":{"record":[{"status":"public","relation":"part_of_dissertation","id":"13312"},{"status":"public","id":"12118","relation":"part_of_dissertation"},{"status":"public","relation":"part_of_dissertation","id":"8910"},{"id":"12522","relation":"research_data","status":"public"}]},"status":"public","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by-nc-sa/4.0/legalcode","name":"Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International (CC BY-NC-SA 4.0)","image":"/images/cc_by_nc_sa.png","short":"CC BY-NC-SA (4.0)"},"type":"dissertation","date_published":"2023-07-21T00:00:00Z","publication_identifier":{"issn":["2663 - 337X"]},"oa":1,"supervisor":[{"orcid":"0000-0001-8342-202X","full_name":"Katsaros, Georgios","first_name":"Georgios","last_name":"Katsaros","id":"38DB5788-F248-11E8-B48F-1D18A9856A87"}]},{"acknowledgement":"The authors acknowledge Alexander Brinkmann, Alessandro Crippa, Andrew Higginbotham, Andrea Iorio, Giordano\r\nScappucci and Christian Schonenberger for helpful discussions.
