We discuss the in-house fabrication of two KTP systems implementing two processes of interest for the quantum optical community. The first sample performs a frequency conversion bridging the gap between the ultraviolet and the infrared range and the sec- ond is an infrared source of decorrelated photon pairs. We show that the performance of the samples is affected by fabrication imperfections and expand the discussion to the case of nonlinear processes in lithium niobate waveguides. We develop a model that provides design rules to optimise the spectral quality of nonlinear devices and discover that such a theory can be extended to nonlinear processes realised in a wide variety of nonlinear systems. To improve the characterisation of our samples, we develop a technique to estimate the losses of the second harmonic field in a nonlinear waveguide system. The work is completed by an in-depth analysis of the effect of the waveguide geometry in deter- mining the dispersion and nonlinear properties of lithium niobate on insulator (LNOI) waveguides. We conclude with a discussion on the impact of fabrication errors on the performance of these systems. v Zusammenfassung Diese Arbeit behandelt die theoretische und experimentelle Untersuchung integri- erter nichtlinearer optischer Bauelemente für quantenoptische Anwendungen. Wir betrachten zwei KTP-Systeme aus eigner Herstellung, welche für die quantenop- tische Gemeinschaft interessante Prozesse realisieren. Die erste Probe führt eine Fre- quenzkonversion durch, um die Lücke zwischen dem Ultraviolett- und dem Infrarot- bereich zu überbrücken. Die zweite Probe ist eine Infrarotquelle für dekorrelierte Pho- tonenpaare. Wir zeigen, dass die nichtlinearen Eigenschaften der Proben durch Imper- fektionen im Herstellungsprozess beeinflusst werden und erweitern die Untersuchun- gen um Lithiumniobat Systeme. Wir entwickeln ein Modell, das Entwurfsregeln zur Optimierung der spektralen Qualität nichtlinearer Bauelemente enthält. Wie zeigen, dass diese Theorie auf eine Vielzahl nichtlinearer Systeme ausgeweitet werden kann. Um die Charakterisierung unserer Proben zu verbessern, entwickeln wir eine Meth- ode zur Verlustabschätzung des zweiten harmonischen Feldes in nichtlinearen Wellen- leitern. Die Arbeit wird durch eine eingehende Analyse des Einflusses der Wellenleit- ergeometrie auf die Bestimmung der Dispersion und der nichtlinearen Eigenschaften von Lithiumniobat auf Isolator (LNOI) Wellenleitern vervollständigt. Wir schließen mit einer Diskussion der Auswirkungen von Fabrikationsfehlern auf die Eigenschaften dieser Systeme. vii Preface The work of this doctoral thesis has been performed during the years 2015-2019 in the IQO (Integrated Quantum Optics) group of Prof. Dr. Christine Silberhorn. We started our doctoral studies with the task of optimising the fabrication of periodically poled waveguides written in potassium titanyl phosphate (KTP). During the first one and a half year, we learnt the pre-existing techniques for the in-house fabrication of periodically poled KTP waveguide and helped optimising them, both by improving the processing steps and by characterising the properties of the fabricated samples. The direct involvement in the fabrication of KTP samples led to a deep understanding of waveguide processing and its limitations. This helped addressing the challenges presented by the fabrication process of nonlinear systems. Beside improving the wave- guide processing, we developed new techniques for the characterisation of the KTP waveguides. In particular, we optimised the technique to measure the propagation losses of these system, providing useful feedback for the improvement of the fabrica- tion process. Alongside the production of KTP samples, we were also actively involved in the modelling of these systems and we helped designing the first periodically poled, rubidium-exchanged ridge KTP waveguide, in collaboration with the group of Prof. Kip (Helmut Schmidt University, Hamburg) - see publications VI and VII here below. Our work in the cleanroom was focused on the production of two different types of KTP samples. The first type implemented a sum frequency generation process to con- vert light from the IR to the UV. The target application was the realisation of a quan- tum frequency converter as an interface between ion qubits and single photons. The second type implemented a parameteric down conversion process for the genertion of heralded pure single photons in the telecom O-band - see publication IV below. Interestingly, the phase matching properties of the second sample were very different from the theoretical expectation. Therefore, we investigated the reasons behind such behaviour and discovered that the effect of fabrication imperfections in our systems was much higher than formerly believed. For this reason, we spent the following years developing a model to properly describe the impact of fabrication imperfections onto the nonlinear performance of the nonlinear systems produced in our cleanroom.

Quantum frequency conversion has been employed as a tool to perform tomographic analysis and manipulation of ultrafast states of quantum light necessary to implement a TM-based encod- ing protocol. While demultiplexing of such states of light has been demonstrated in the Quantum Pulse Gate (QPG), a multiplexing device is needed to complete an experimental framework for TM encoding. In this work we demonstrate the reverse process of the QPG. A dispersion-engineered difference frequency generation in non-linear optical waveguides is employed to imprint the pulse shape of the pump pulse onto the output. This transformation is unitary and can be more efficient than classical pulse shaping methods. We experimentally study the process by shaping the first five orders of Hermite-Gauss modes of various bandwidths. Finally, we establish and model the limits of practical, reliable shaping operation. High-dimensional encoding can potentially increase the To design a DFG pulse shaping device such as the security of quantum communication protocols as well as QPS, one has to first revisit the working principle be- the information capacity of a single photon [1, 2].

The option to directly monitor the walker's probability distribution makes this optical platform ideally suited for the experimental observation of the unique signatures of the one- dimensional topological Anderson transition. We analytically calculate the probability distribution describing the quantum critical walk in terms of a (time staggered) spin polarization signal and propose a concrete experimental protocol for its measurement. Numerical simulations back the realizability of our blueprint with current date experimental hardware. I.

  • Driven Quantum Walks
    Driven Quantum Walks Craig S. Hamilton,1, ∗ Regina Kruse,2 Linda Sansoni,2 Christine Silberhorn,2 and Igor Jex1 1FNSPE, Czech Technical University in Prague, Bˇrehov´a7, 115 19, Praha 1, Czech Republic 2Applied Physics, University of Paderborn, Warburger Straße 100, D-33098 Paderborn, Germany In this letter we introduce the concept of a driven quantum walk. This work is motivated by recent theoretical and experimental progress that combines quantum walks and parametric down- conversion, leading to fundamentally different phenomena. We compare these striking differences by relating the driven quantum walks to the original quantum walk. Next, we illustrate typical dynamics of such systems and show these walks can be controlled by various pump configurations and phase matchings. Finally, we end by proposing an application of this process based on a quantum search algorithm that performs faster than a classical search.
