By defining an appropriate thermodynamic\r\nlimit, we demonstrated that the observed bistability is a genuine signature of a first-order\r\nphase transition in this system. This work provides insight into non-equilibrium quantum\r\ndynamics and phase transitions in driven-dissipative open quantum systems.\r\nThe second project focuses on the experimental realization of a phase-conjugate receiver for\r\nquantum illumination (QI), a quantum sensing protocol that enhances target detection in noisy\r\nenvironments using entangled light. While an ideal spontaneous parametric down-conversion\r\n(SPDC) source and receiver could, in theory, provide up to a 6 dB advantage over classical\r\nillumination, no such ideal receiver exists. Instead, we explore an experimental realization of a\r\nphase-conjugate receiver for QI in the microwave regime at millikelvin temperatures using a\r\nJosephson parametric converter (JPC) as a source of continuous-variable Gaussian entangled\r\nsignal-idler pairs, where a maximum 3 dB advantage is theoretically achievable. We investigate\r\nkey experimental limitations that constrain practical QI performance, contributing to the\r\ndevelopment of quantum-enhanced sensing.\r\nAdditionally, this thesis presents efficient digital signal processing (DSP) techniques implemented in C++ and Python in collaboration with Przemysław Zieliński and Luka Drmić. These\r\nmethods, optimized using the Intel Integrated Performance Primitives (IPP) library, have been\r\nessential in data acquisition, noise filtering, and correlation analysis across multiple research\r\nprojects. Although not real-time, these DSP techniques significantly enhance the accuracy of\r\nquantum measurements.\r\nOverall, this thesis advances quantum-enhanced sensing by establishing the thermodynamic\r\nlimit in a single transmon-cavity system and experimentally exploring a phase-conjugate receiver\r\nfor QI. These findings contribute to quantum metrology, particularly for weak signal detection\r\nand remote sensing in noisy environments.\r\n","lang":"eng"}],"acknowledgement":"I acknowledge the generous financial support of the Austrian Science Fund (FWF) via BeyondC\r\n(F7105) and the European Union’s Horizon 2020 research and innovation program (FETopen\r\nQUARTET, Grant Agreement No. 862644), which made this research possible.

However, the predicted scaling from a microscopic behavior—dominated by quantum fluctuations—to a macroscopic one—characterized by stable phases—and the associated exponents and phase diagram have not been observed so far. In this work we couple a single transmon qubit with a fixed coupling strength 𝑔 to a superconducting cavity that is in situ bandwidth 𝜅 tunable to controllably approach this thermodynamic limit. Even though the system remains microscopic, we observe its behavior becoming increasingly macroscopic as a function of 𝑔/𝜅. For the highest realized 𝑔/𝜅 of approximately 287, the system switches with a characteristic timescale as long as 6 s between a bright coherent state with approximately 8×103 intracavity photons and the vacuum state. This exceeds the microscopic timescales by 6 orders of magnitude and approaches the perfect hysteresis expected between two macroscopic attractors in the thermodynamic limit. These findings and interpretation are qualitatively supported by neoclassical theory and large-scale quantum-jump Monte Carlo simulations. Besides shedding more light on driven-dissipative physics in the limit of strong light-matter coupling, this system might also find applications in quantum sensing and metrology."}],"arxiv":1,"file_date_updated":"2024-06-28T12:04:43Z","month":"02","type":"journal_article","project":[{"_id":"237CBA6C-32DE-11EA-91FC-C7463DDC885E","name":"Quantum readout techniques and technologies","grant_number":"862644","call_identifier":"H2020"},{"call_identifier":"FWF","_id":"3AC91DDA-15DF-11EA-824D-93A3E7B544D1","name":"FWF Open Access Fund"},{"_id":"bdb108fd-d553-11ed-ba76-83dc74a9864f","grant_number":"F07105","name":"QUANTUM INFORMATION SYSTEMS BEYOND CLASSICAL CAPABILITIES / P5- Integration of Superconducting Quantum Circuits"}],"external_id":{"arxiv":["2210.14182"],"isi":["001171652500001"]},"title":"Emergent macroscopic bistability induced by a single superconducting qubit","article_processing_charge":"Yes","date_created":"2024-06-27T10:58:06Z","oa_version":"Published Version","doi":"10.1103/prxquantum.5.010327","department":[{"_id":"JoFi"},{"_id":"AnHi"}],"publication":"PRX Quantum","status":"public","citation":{"ieee":"R.

Tunable directionality can be achieved by applying external magnetic fields that modify optical selection rules, by using nonlinear effects, or interactions with vibrations. However, these approaches are less suitable to control microwave photon propagation inside integrated superconducting quantum devices. Here, we demonstrate on-demand tunable directional scattering based on two periodically modulated transmon qubits coupled to a transmission line at a fixed distance. By changing the relative phase between the modulation tones, we realize unidirectional forward or backward photon scattering. Such an in-situ switchable mirror represents a versatile tool for intra- and inter-chip microwave photonic processors. In the future, a lattice of qubits can be used to realize topological circuits that exhibit strong nonreciprocity or chirality.","lang":"eng"}],"file_date_updated":"2023-06-06T07:31:20Z","arxiv":1,"type":"journal_article","month":"05","date_published":"2023-05-24T00:00:00Z","_id":"13117","related_material":{"record":[{"id":"13124","relation":"research_data","status":"public"},{"id":"19533","relation":"dissertation_contains","status":"public"}]},"isi":1,"pmid":1,"publication_status":"published","intvolume":"        14","language":[{"iso":"eng"}]}]
