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"}],"degree_awarded":"PhD","doi":"10.15479/at:ista:12132","day":"26","language":[{"iso":"eng"}],"has_accepted_license":"1","month":"09","acknowledged_ssus":[{"_id":"NanoFab"},{"_id":"M-Shop"},{"_id":"EM-Fac"}],"oa_version":"Published Version","project":[{"name":"International IST Doctoral Program","grant_number":"665385","_id":"2564DBCA-B435-11E9-9278-68D0E5697425","call_identifier":"H2020"},{"call_identifier":"H2020","_id":"26336814-B435-11E9-9278-68D0E5697425","name":"A Fiber Optic Transceiver for Superconducting Qubits","grant_number":"758053"},{"call_identifier":"H2020","_id":"237CBA6C-32DE-11EA-91FC-C7463DDC885E","grant_number":"862644","name":"Quantum readout techniques and technologies"}],"status":"public","user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","file":[{"date_updated":"2023-01-26T23:30:44Z","content_type":"application/pdf","file_name":"Final_Thesis_ES_Redchenko.pdf","embargo":"2022-12-28","date_created":"2023-01-25T09:41:49Z","file_size":56076868,"checksum":"39eabb1e006b41335f17f3b29af09648","file_id":"12367","creator":"cchlebak","relation":"main_file","access_level":"open_access"}],"date_published":"2022-09-26T00:00:00Z","type":"dissertation","supervisor":[{"orcid":"0000-0001-8112-028X","full_name":"Fink, Johannes M","first_name":"Johannes M","last_name":"Fink","id":"4B591CBA-F248-11E8-B48F-1D18A9856A87"}],"oa":1,"publication_identifier":{"isbn":["978-3-99078-024-4"],"issn":["2663-337X"]}},{"author":[{"full_name":"Peruzzo, Matilda","orcid":"0000-0002-3415-4628","last_name":"Peruzzo","first_name":"Matilda","id":"3F920B30-F248-11E8-B48F-1D18A9856A87"},{"id":"2AED110C-F248-11E8-B48F-1D18A9856A87","last_name":"Hassani","first_name":"Farid","full_name":"Hassani, Farid","orcid":"0000-0001-6937-5773"},{"last_name":"Szep","first_name":"Grisha","full_name":"Szep, Grisha"},{"id":"42F71B44-F248-11E8-B48F-1D18A9856A87","full_name":"Trioni, Andrea","last_name":"Trioni","first_name":"Andrea"},{"id":"2C21D6E8-F248-11E8-B48F-1D18A9856A87","last_name":"Redchenko","first_name":"Elena","full_name":"Redchenko, Elena"},{"full_name":"Zemlicka, Martin","first_name":"Martin","last_name":"Zemlicka","id":"2DCF8DE6-F248-11E8-B48F-1D18A9856A87"},{"id":"4B591CBA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-8112-028X","full_name":"Fink, Johannes M","first_name":"Johannes M","last_name":"Fink"}],"_id":"13057","title":"Geometric superinductance qubits: Controlling phase delocalization across a single Josephson junction","month":"10","date_created":"2023-05-23T13:42:27Z","article_processing_charge":"No","department":[{"_id":"JoFi"}],"oa_version":"Published Version","publisher":"Zenodo","type":"research_data_reference","date_published":"2021-10-22T00:00:00Z","year":"2021","citation":{"ieee":"M.

These features suggest electro-optic-based devices as candidates for entangled optical frequency comb sources. In the present work, I study the generation of entangled optical frequency combs in millimeter-sized resonant electro-optic modulators. These devices profit from the experimentally proven advantages such as nearly constant optical free spectral ranges over several gigahertz, and high optical and microwave quality factors. The generation of frequency multiplexed quantum channels with spectral bandwidth in the MHz range for conservative parameter values paves the way towards novel uses in long-distance hybrid quantum networks, quantum key distribution, enhanced optical metrology, and quantum computing.","lang":"eng"}],"acknowledgement":"I thank Prof. Shabir Barzanjeh and Dr. Ulrich Vogl for the fruitful discussions.\r\n","volume":103,"_id":"9242","scopus_import":"1","author":[{"orcid":"0000-0001-6249-5860","full_name":"Rueda Sanchez, Alfredo R","first_name":"Alfredo R","last_name":"Rueda Sanchez","id":"3B82B0F8-F248-11E8-B48F-1D18A9856A87"}],"issue":"2","publication_status":"published","article_processing_charge":"No","date_created":"2021-03-14T23:01:33Z","department":[{"_id":"JoFi"}],"title":"Frequency-multiplexed hybrid optical entangled source based on the Pockels effect","intvolume":"       103","quality_controlled":"1","publisher":"American Physical Society","article_type":"original","date_published":"2021-02-11T00:00:00Z","type":"journal_article","publication_identifier":{"eissn":["2469-9934"],"issn":["2469-9926"]},"oa":1,"main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/2010.05356"}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","status":"public","publication":"Physical Review A","oa_version":"Preprint","month":"02","article_number":"023708","language":[{"iso":"eng"}]},{"language":[{"iso":"eng"}],"keyword":["Application note"],"page":"9","quality_controlled":"1","publisher":"Bluefors Oy","author":[{"last_name":"Lake","first_name":"Russell","full_name":"Lake, Russell"},{"last_name":"Simbierowicz","first_name":"Slawomir","full_name":"Simbierowicz, Slawomir"},{"last_name":"Krantz","first_name":"Philip","full_name":"Krantz, Philip"},{"id":"2AED110C-F248-11E8-B48F-1D18A9856A87","full_name":"Hassani, Farid","last_name":"Hassani","first_name":"Farid"},{"id":"4B591CBA-F248-11E8-B48F-1D18A9856A87","full_name":"Fink, Johannes M","orcid":"0000-0001-8112-028X","last_name":"Fink","first_name":"Johannes M"}],"_id":"10644","month":"04","title":"The Bluefors dilution refrigerator as an integrated quantum measurement system","alternative_title":["Bluefors Blog"],"publication_status":"published","oa_version":"Published Version","department":[{"_id":"JoFi"}],"article_processing_charge":"No","date_created":"2022-01-19T08:29:57Z","status":"public","user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","main_file_link":[{"open_access":"1","url":"https://bluefors.com/blog/integrated-quantum-measurement-system/"}],"place":"Helsinki, Finland","date_published":"2021-04-20T00:00:00Z","type":"other_academic_publication","date_updated":"2022-01-19T09:11:33Z","year":"2021","citation":{"ista":"Lake R, Simbierowicz S, Krantz P, Hassani F, Fink JM. 2021.

Our motivation is twofold. First, we provide pre-qualification data that the Bluefors cryostat, including filtering and wiring, can support long-lived qubits. Second, we demonstrate that the Keysight system (controlled using Labber) provides a straightforward solution to perform these characterization measurements. This document is intended as a brief guide for starting an experimental platform for testing superconducting qubits. The setup described here is an immediate jumping off point for a suite of applications including testing quantum logical gates, quantum optics with microwaves, or even using the qubit itself as a sensitive probe of local electromagnetic fields. Qubit measurements rely on high performance of both the physical sample environment and the measurement electronics.

Bluefors and Zurich Instruments have supported the growth of this field from the 2010s onwards by providing well-engineered and reliable measurement infrastructure [2]– [6]. Having a long and stable qubit lifetime is a critical system property. Therefore, considerable effort has already gone into measuring qubit energy-relaxation timescales and their fluctuations, see Refs. [7]–[10] among others. Accurately extracting the statistics of a quantum device requires users to perform time consuming measurements. One measurement challenge is that the detection of the state-dependent\r\nresponse of a superconducting resonator due to a dispersively-coupled qubit requires an inherently low signal level. Consequently, measurements must be performed using a microwave probe that contains only a few microwave photons. Improving the signal-to-noise ratio (SNR) by using near-quantum limited parametric amplifiers as well as the use of optimized signal processing enabled by efficient room temperature instrumentation help to reduce measurement time. An empirical observation for fixed frequency transmons from recent literature is that as the energy-relaxation time 𝑇𝑇1 increases, so do its natural temporal fluctuations [7], [10]. This necessitates many repeated measurements to understand the statistics (see for example, Ref. [10]). In addition, as state-of-the-art qubits increase in lifetime, longer\r\nmeasurement times are expected to obtain accurate statistics. As described below, the scaling of the widths of the qubit energy-relaxation distributions also reveal clues about the origin of the energy-relaxation.","lang":"eng"}],"day":"03","type":"other_academic_publication","date_published":"2021-06-03T00:00:00Z","citation":{"short":"S.

The energy of photons in the gigahertz domain is too low to allow transmission through the noisy room-temperature environment, where the signal would be lost in thermal noise. Optical photons, on the other hand, have much higher energies, and signals can be detected using highly efficient single-photon detectors. Transduction from microwave to optical frequencies is therefore a potential enabling technology for quantum devices. However, in such a device the optical pump can be a source of thermal noise and thus degrade the fidelity; the similarity of input microwave state to the output optical state. In order to investigate the magnitude of this effect we model the sub-Kelvin thermal behavior of an electro-optic transducer based on a lithium niobate whispering gallery mode resonator. We find that there is an optimum power level for a continuous pump, whilst pulsed operation of the pump increases the fidelity of the conversion."}],"arxiv":1,"doi":"10.1088/2058-9565/ac0f36","day":"15"},{"type":"dissertation","date_published":"2021-08-19T00:00:00Z","publication_identifier":{"issn":["2663-337X"],"isbn":["978-3-99078-013-8"]},"oa":1,"supervisor":[{"id":"4B591CBA-F248-11E8-B48F-1D18A9856A87","full_name":"Fink, Johannes M","orcid":"0000-0001-8112-028X","last_name":"Fink","first_name":"Johannes M"}],"file":[{"date_created":"2021-08-16T09:33:21Z","checksum":"3cd1986efde5121d7581f6fcf9090da8","file_size":151387283,"date_updated":"2021-09-06T08:39:47Z","content_type":"application/x-zip-compressed","file_name":"GeometricSuperinductorsForCQED.zip","access_level":"closed","relation":"source_file","file_id":"9924","creator":"mperuzzo"},{"date_created":"2021-08-18T14:20:06Z","file_size":17596344,"checksum":"50928c621cdf0775d7a5906b9dc8602c","date_updated":"2021-09-06T08:39:47Z","file_name":"GeometricSuperinductorsAndTheirApplicationsIncQED-1b.pdf","content_type":"application/pdf","access_level":"open_access","relation":"main_file","file_id":"9939","creator":"mperuzzo"},{"date_created":"2021-08-18T14:20:09Z","checksum":"37f486aa1b622fe44af00d627ec13f6c","file_size":17592425,"date_updated":"2021-09-06T08:39:47Z","content_type":"application/pdf","file_name":"GeometricSuperinductorsAndTheirApplicationsIncQED-2b.pdf","relation":"other","access_level":"closed","description":"Extra copy of the thesis as PDF/A-2b","file_id":"9940","creator":"mperuzzo"}],"status":"public","related_material":{"record":[{"relation":"part_of_dissertation","id":"9928","status":"public"},{"status":"public","relation":"part_of_dissertation","id":"8755"}]},"user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","has_accepted_license":"1","oa_version":"Published Version","acknowledged_ssus":[{"_id":"NanoFab"},{"_id":"M-Shop"}],"month":"08","keyword":["quantum computing","superinductor","quantum metrology"],"language":[{"iso":"eng"}],"citation":{"chicago":"Peruzzo, Matilda. “Geometric Superinductors and Their Applications in Circuit Quantum Electrodynamics.” Institute of Science and Technology Austria, 2021. <a href=\"https://doi.org/10.15479/at:ista:9920\">https://doi.org/10.15479/at:ista:9920</a>.","ieee":"M.

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"}],"ddc":["539"],"_id":"9920","author":[{"first_name":"Matilda","last_name":"Peruzzo","orcid":"0000-0002-3415-4628","full_name":"Peruzzo, Matilda","id":"3F920B30-F248-11E8-B48F-1D18A9856A87"}],"department":[{"_id":"GradSch"},{"_id":"JoFi"}],"article_processing_charge":"No","date_created":"2021-08-16T09:44:09Z","publication_status":"published","title":"Geometric superinductors and their applications in circuit quantum electrodynamics","alternative_title":["ISTA Thesis"],"page":"149","file_date_updated":"2021-09-06T08:39:47Z","publisher":"Institute of Science and Technology Austria"},{"keyword":["quantum physics","mesoscale and nanoscale physics"],"language":[{"iso":"eng"}],"month":"11","project":[{"name":"Integrating superconducting quantum circuits","grant_number":"F07105","call_identifier":"FWF","_id":"26927A52-B435-11E9-9278-68D0E5697425"},{"grant_number":"665385","name":"International IST Doctoral Program","_id":"2564DBCA-B435-11E9-9278-68D0E5697425","call_identifier":"H2020"},{"name":"Hybrid Semiconductor - Superconductor Quantum Devices","_id":"2622978C-B435-11E9-9278-68D0E5697425"}],"oa_version":"Published Version","acknowledged_ssus":[{"_id":"NanoFab"},{"_id":"M-Shop"}],"has_accepted_license":"1","publication":"PRX Quantum","related_material":{"record":[{"id":"13057","relation":"research_data","status":"public"},{"status":"public","id":"9920","relation":"dissertation_contains"}]},"status":"public","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","file":[{"creator":"cchlebak","file_id":"10641","relation":"main_file","success":1,"access_level":"open_access","file_name":"2021_PRXQuantum_Peruzzo.pdf","content_type":"application/pdf","date_updated":"2022-01-18T11:29:33Z","checksum":"36eb41ea43d8ca22b0efab12419e4eb2","file_size":4247422,"date_created":"2022-01-18T11:29:33Z"}],"oa":1,"publication_identifier":{"eissn":["2691-3399"]},"type":"journal_article","date_published":"2021-11-24T00:00:00Z","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)"},"article_type":"original","publisher":"American Physical Society","file_date_updated":"2022-01-18T11:29:33Z","ec_funded":1,"quality_controlled":"1","page":"040341","intvolume":"         2","title":"Geometric superinductance qubits: Controlling phase delocalization across a single Josephson junction","article_processing_charge":"No","department":[{"_id":"JoFi"},{"_id":"NanoFab"},{"_id":"M-Shop"}],"date_created":"2021-08-17T08:14:18Z","publication_status":"published","issue":"4","author":[{"id":"3F920B30-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-3415-4628","full_name":"Peruzzo, Matilda","first_name":"Matilda","last_name":"Peruzzo"},{"first_name":"Farid","last_name":"Hassani","orcid":"0000-0001-6937-5773","full_name":"Hassani, Farid","id":"2AED110C-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Szep, Gregory","last_name":"Szep","first_name":"Gregory"},{"id":"42F71B44-F248-11E8-B48F-1D18A9856A87","full_name":"Trioni, Andrea","first_name":"Andrea","last_name":"Trioni"},{"id":"2C21D6E8-F248-11E8-B48F-1D18A9856A87","first_name":"Elena","last_name":"Redchenko","full_name":"Redchenko, Elena"},{"first_name":"Martin","last_name":"Zemlicka","full_name":"Zemlicka, Martin","id":"2DCF8DE6-F248-11E8-B48F-1D18A9856A87"},{"id":"4B591CBA-F248-11E8-B48F-1D18A9856A87","last_name":"Fink","first_name":"Johannes M","full_name":"Fink, Johannes M","orcid":"0000-0001-8112-028X"}],"scopus_import":"1","_id":"9928","ddc":["530"],"volume":2,"acknowledgement":"We thank W.

In one, the inductor is replaced by a nonlinear Josephson junction to realize the widely used charge qubits with a compact phase variable and a discrete charge wave function. In the other, the junction is added in parallel, which gives rise to an extended phase variable, continuous wave functions, and a rich energy-level structure due to the loop topology. While the corresponding rf superconducting quantum interference device Hamiltonian was introduced as a quadratic quasi-one-dimensional potential approximation to describe the fluxonium qubit implemented with long Josephson-junction arrays, in this work we implement it directly using a linear superinductor formed by a single uninterrupted aluminum wire. We present a large variety of qubits, all stemming from the same circuit but with drastically different characteristic energy scales. This includes flux and fluxonium qubits but also the recently introduced quasicharge qubit with strongly enhanced zero-point phase fluctuations and a heavily suppressed flux dispersion. The use of a geometric inductor results in high reproducibility of the inductive energy as guaranteed by top-down lithography—a key ingredient for intrinsically protected superconducting qubits."}],"day":"24","doi":"10.1103/PRXQuantum.2.040341","arxiv":1,"external_id":{"isi":["000723015100001"],"arxiv":["2106.05882"]},"isi":1,"citation":{"apa":"Peruzzo, M., Hassani, F., Szep, G., Trioni, A., Redchenko, E., Zemlicka, M., &#38; Fink, J.

Here, we experimentally investigate the concept of quantum illumination at microwave frequencies. We generate entangled fields to illuminate a room-temperature object at a distance of 1 m in a free-space detection setup. We implement a digital phase-conjugate receiver based on linear quadrature measurements that outperforms a symmetric classical noise radar in the same conditions, despite the entanglement-breaking signal path. Starting from experimental data, we also simulate the case of perfect idler photon number detection, which results in a quantum advantage compared with the relative classical benchmark.

These circuit elements have a characteristic impedance exceeding the resistance quantum RQ ≈ 6.45 kΩ which leads to a suppression of ground state charge fluctuations. Applications include the realization of hardware protected qubits for fault tolerant quantum computing, improved coupling to small dipole moment objects and defining a new quantum metrology standard for the ampere. In this work we refute the widespread notion that superinductors can only be implemented based on kinetic inductance, i.e. using disordered superconductors or Josephson junction arrays. We present modeling, fabrication and characterization of 104 planar aluminum coil resonators with a characteristic impedance up to 30.9 kΩ at 5.6 GHz and a capacitance down to ≤ 1 fF, with lowloss and a power handling reaching 108 intra-cavity photons. Geometric superinductors are free of uncontrolled tunneling events and offer high reproducibility, linearity and the ability to couple magnetically - properties that significantly broaden the scope of future quantum circuits.

Surprisingly, the Zeeman paramagnetic effects dominate over orbital coupling on both sides of the transition. In superconducting state it is evidenced by a high upper critical magnetic field 𝐵𝑐2, by its square root dependence on temperature, as well as by the Zeeman splitting of the quasiparticle density of states (DOS) measured by scanning tunneling microscopy. At 𝐵𝑐2 a logarithmic anomaly in DOS is observed. This anomaly is further enhanced in increasing magnetic field, which is explained by the Zeeman splitting of the Altshuler-Aronov DOS driving\r\nthe system into a more insulating or resistive state.

The converter uses a high-quality factor whispering gallery\r\nmode (WGM) resonator providing naturally narrow bandwidth and therefore might be useful for applications like microwave hyperspectral sensing. The upconversion process is explained by\r\nproviding essential information about photon conversion efficiency and sensitivity.

The advantage over classical strategies is evident at low signal brightness, a feature which could make the protocol an ideal prototype for non-invasive scanning or low-power short-range radar. Here we experimentally investigate the concept of quantum illumination at microwave frequencies, by generating entangled fields using a Josephson parametric converter which are then amplified to illuminate a room-temperature object at a distance of 1 meter. Starting from experimental data, we simulate the case of perfect idler photon number detection, which results in a quantum advantage compared to the relative classical benchmark. Our results highlight the opportunities and challenges on the way towards a first room-temperature application of microwave quantum circuits.","lang":"eng"}],"year":"2020","citation":{"short":"S.
