In contrast to classical\r\ncomputers based on bits that are represented by a single binary value, 0 or 1, quantum\r\nbits (or qubits) can be in a superposition of both. Thus, quantum computers can store\r\nand handle more information at the same time and a quantum advantage has already\r\nbeen demonstrated for two types of computational tasks. Rapid progress in academic\r\nand industry labs accelerates the development of superconducting processors which may\r\nsoon fnd applications in complex computations, chemical simulations, cryptography, and\r\noptimization. Now that these machines are scaled up to tackle such problems the questions\r\nof qubit interconnects and networks becomes very relevant. How to route signals on-chip\r\nbetween diferent processor components? What is the most efcient way to entangle\r\nqubits? And how to then send and process entangled signals between distant cryostats\r\nhosting superconducting processors?\r\nIn this thesis, we are looking for solutions to these problems by studying the collective\r\nbehavior of superconducting qubit ensembles. We frst demonstrate on-demand tunable\r\ndirectional scattering of microwave photons from a pair of qubits in a waveguide. Such a\r\ndevice can route microwave photons on-chip with a high diode efciency. Then we focus\r\non studying ultra-strong coupling regimes between light (microwave photons) and matter\r\n(superconducting qubits), a regime that could be promising for extremely fast multi-qubit\r\nentanglement generation. Finally, we show coherent pulse storage and periodic revivals\r\nin a fve qubit ensemble strongly coupled to a resonator. Such a reconfgurable storage\r\ndevice could be used as part of a quantum repeater that is needed for longer-distance\r\nquantum communication.\r\nThe achieved high degree of control over multi-qubit ensembles highlights not only the\r\nbeautiful physics of circuit quantum electrodynamics, it also represents the frst step\r\ntoward new quantum simulation and communication methods, and certain techniques\r\nmay also fnd applications in future superconducting quantum computing hardware.\r\n","lang":"eng"}],"_id":"12366","year":"2022"},{"article_processing_charge":"No","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","publisher":"Institute of Science and Technology Austria","department":[{"_id":"GradSch"},{"_id":"JoFi"}],"title":"Geometric superinductors and their applications in circuit quantum electrodynamics","degree_awarded":"PhD","author":[{"last_name":"Peruzzo","first_name":"Matilda","id":"3F920B30-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-3415-4628","full_name":"Peruzzo, Matilda"}],"file":[{"date_created":"2021-08-16T09:33:21Z","access_level":"closed","date_updated":"2021-09-06T08:39:47Z","file_id":"9924","checksum":"3cd1986efde5121d7581f6fcf9090da8","content_type":"application/x-zip-compressed","relation":"source_file","file_size":151387283,"creator":"mperuzzo","file_name":"GeometricSuperinductorsForCQED.zip"},{"file_name":"GeometricSuperinductorsAndTheirApplicationsIncQED-1b.pdf","creator":"mperuzzo","file_size":17596344,"relation":"main_file","content_type":"application/pdf","checksum":"50928c621cdf0775d7a5906b9dc8602c","file_id":"9939","date_updated":"2021-09-06T08:39:47Z","access_level":"open_access","date_created":"2021-08-18T14:20:06Z"},{"date_updated":"2021-09-06T08:39:47Z","file_id":"9940","description":"Extra copy of the thesis as PDF/A-2b","checksum":"37f486aa1b622fe44af00d627ec13f6c","date_created":"2021-08-18T14:20:09Z","access_level":"closed","file_name":"GeometricSuperinductorsAndTheirApplicationsIncQED-2b.pdf","content_type":"application/pdf","relation":"other","file_size":17592425,"creator":"mperuzzo"}],"day":"19","keyword":["quantum computing","superinductor","quantum metrology"],"language":[{"iso":"eng"}],"doi":"10.15479/at:ista:9920","publication_identifier":{"isbn":["978-3-99078-013-8"],"issn":["2663-337X"]},"_id":"9920","year":"2021","file_date_updated":"2021-09-06T08:39:47Z","date_created":"2021-08-16T09:44:09Z","page":"149","type":"dissertation","month":"08","oa_version":"Published Version","abstract":[{"text":"This work is concerned with two fascinating circuit quantum electrodynamics components, the Josephson junction and the geometric superinductor, and the interesting experiments that can be done by combining the two. The Josephson junction has revolutionized the field of superconducting circuits as a non-linear dissipation-less circuit element and is used in almost all superconducting qubit implementations since the 90s. On the other hand, the superinductor is a relatively new circuit element introduced as a key component of the fluxonium qubit in 2009. This is an inductor with characteristic impedance larger than the resistance quantum and self-resonance frequency in the GHz regime. The combination of these two elements can occur in two fundamental ways: in parallel and in series. When connected in parallel the two create the fluxonium qubit, a loop with large inductance and a rich energy spectrum reliant on quantum tunneling. On the other hand placing the two elements in series aids with the measurement of the IV curve of a single Josephson junction in a high impedance environment. In this limit theory predicts that the junction will behave as its dual element: the phase-slip junction. While the Josephson junction acts as a non-linear inductor the phase-slip junction has the behavior of a non-linear capacitance and can be used to measure new Josephson junction phenomena, namely Coulomb blockade of Cooper pairs and phase-locked Bloch oscillations. The latter experiment allows for a direct link between frequency and current which is an elusive connection in quantum metrology. This work introduces the geometric superinductor, a superconducting circuit element where the high inductance is due to the geometry rather than the material properties of the superconductor, realized from a highly miniaturized superconducting planar coil. These structures will be described and characterized as resonators and qubit inductors and progress towards the measurement of phase-locked Bloch oscillations will be presented.","lang":"eng"}],"date_updated":"2024-09-10T12:23:56Z","related_material":{"record":[{"status":"public","id":"9928","relation":"part_of_dissertation"},{"status":"public","id":"8755","relation":"part_of_dissertation"}]},"citation":{"ama":"Peruzzo M.
