Book Description
Essential to the development of hardware for optical quantum information processing is the integration of solid-state quantum emitters into low-loss photonics. Quantum emitters provide discrete energy levels, which can be used as qubit states and driven with photons. This light-matter interaction enables the generation, manipulation, and transmission of information. Photonic devices allow us to confine light at the nanoscale to enhance the interaction between local (quantum emitter) and flying (photon) qubits. In recent years, extensive research has been conducted to find quantum emitters with narrow linewidths, high quantum efficiencies, and long coherence times. Some of the most promising quantum emitters have been incorporated into photonic devices and have facilitated fundamental studies of light-matter interactions, the development of optical control schemes, and the generation of non-classical light. These works have mostly been confined to single devices with single quantum emitters and current efforts are directed at scaling to photonic circuits connecting arrays of quantum emitters. This endeavor further increases the requirements on quantum emitters, as they have to be generated with nanoscale precision and near-identical properties across the entire chip. Clever engineering of photonics can facilitate meeting these requirements. However, the development of low-loss photonic circuits remains a challenge of its own, as the most promising quantum emitters are hosted in materials non-standard in the photonics industry. The realization of quantum photonic circuits therefore requires the simultaneous development of quantum emitters and their corresponding photonics. In my thesis, I summarize our contributions to the development of quantum photonics. I discuss how we use semiconductor quantum dots strongly coupled to photonic cavities to demonstrate the coherent generation of indistinguishable, on-demand single photons, as well as multiple photons at a time. Such systems could be used as non-classical light sources for quantum communication and measurement-based quantum computation. However, scaling from single devices to large quantum circuits is challenging, due to the prohibitively large inhomogeneous broadening and random positioning of quantum dots. In contrast, color centers are atomic-scale defects, which can be generated in site-specific locations and exhibit much smaller inhomogeneous broadening than quantum dots. We have thus worked to develop color centers in diamond and 4H-silicon carbide and their host materials into scalable quantum photonic platforms. The host materials diamond and 4H-silicon carbide are new in the field of photonics and as such required us to develop novel fabrication protocols. Leveraging these fabrication techniques and inverse-design algorithms that account for fabrication constraints, we developed photonic platforms in diamond and 4H-silicon carbide for classical, nonlinear, and quantum optics.
Strong Light-matter Coupling
Author: Leong Chuan KwekPublisher: World Scientific
ISBN: 9814460354
Category : Science
Languages : en
Pages : 303
Book Description
The physics of strong light-matter coupling has been addressed in different scientific communities over the last three decades. Since the early eighties, atoms coupled to optical and microwave cavities have led to pioneering demonstrations of cavity quantum electrodynamics, Gedanken experiments, and building blocks for quantum information processing, for which the Nobel Prize in Physics was awarded in 2012. In the framework of semiconducting devices, strong coupling has allowed investigations into the physics of Bose gases in solid-state environments, and the latter holds promise for exploiting light-matter interaction at the single-photon level in scalable architectures. More recently, impressive developments in the so-called superconducting circuit QED have opened another fundamental playground to revisit cavity quantum electrodynamics for practical and fundamental purposes. This book aims at developing the necessary interface between these communities, by providing future researchers with a robust conceptual, theoretical and experimental basis on strong light-matter coupling, both in the classical and in the quantum regimes. In addition, the emphasis is on new forefront research topics currently developed around the physics of strong light-matter interaction in the atomic and solid-state scenarios.
Quantum Simulations with Photons and Polaritons

ISBN: 3319520253
Category : Science
Languages : en
Pages : 220
Book Description
This book reviews progress towards quantum simulators based on photonic and hybrid light-matter systems, covering theoretical proposals and recent experimental work. Quantum simulators are specially designed quantum computers. Their main aim is to simulate and understand complex and inaccessible quantum many-body phenomena found or predicted in condensed matter physics, materials science and exotic quantum field theories. Applications will include the engineering of smart materials, robust optical or electronic circuits, deciphering quantum chemistry and even the design of drugs. Technological developments in the fields of interfacing light and matter, especially in many-body quantum optics, have motivated recent proposals for quantum simulators based on strongly correlated photons and polaritons generated in hybrid light-matter systems. The latter have complementary strengths to cold atom and ion based simulators and they can probe for example out of equilibrium phenomena in a natural driven-dissipative setting. This book covers some of the most important works in this area reviewing the proposal for Mott transitions and Luttinger liquid physics with light, to simulating interacting relativistic theories, topological insulators and gauge field physics. The stage of the field now is at a point where on top of the numerous theory proposals; experiments are also reported. Connecting to the theory proposals presented in the chapters, the main experimental quantum technology platforms developed from groups worldwide to realize photonic and polaritonic simulators in the laboratory are also discussed. These include coupled microwave resonator arrays in superconducting circuits, semiconductor based polariton systems, and integrated quantum photonic chips. This is the first book dedicated to photonic approaches to quantum simulation, reviewing the fundamentals for the researcher new to the field, and providing a complete reference for the graduate student starting or already undergoing PhD studies in this area.

Book Description
Photonics and optics are ubiquitous in our daily lives. By exploiting the quantum mechanical nature of light and matter, quantum optics holds promise to revolutionize communication, computing, metrology, and sensing. One class of quantum matter that interacts strongly with light is solid state color centers. These color centers are optically active lattice defects hosted in large bandgap materials such as diamond, which can serve as individual quantum nodes interacting in a quantum network through the emitted photons. In this dissertation, we explore a type of color center in diamond called silicon-vacancy (SiV) center, which presents a promising platform for implementation of quantum technologies. In particular, we will introduce the background on the photo-physics of SiV centers in diamond, and then walk through our journey studying this color center. We start by studying the optical properties of SiVs in nanodiamonds, and created hybrid diamond-silicon carbide (SiC) platforms to take advantage of the material properties of both diamond and SiC. Next, we discuss optical coherent control of optical transition of a single SiV center in a nanopillar array platform, which is a step towards scalable, on-chip quantum systems. Lastly, we discuss our efforts to create SiV-photon interface by embedding single SiV centers in diamond optical resonators. Using this platform, we demonstrate strong Purcell enhancement and cavity-enhanced Raman emission from a single color center, thereby achieving a large frequency tuning range of 100 GHz for Raman photon emission.

Book Description
Quantum dots (QDs) coupled to optical cavities constitute a scalable, robust, on-chip, semiconductor platform for probing fundamental cavity quantum electrodynamics. Very strong interaction between light and matter can be achieved in this system as a result of the eld localization inside sub-cubic wavelength volumes leading to vacuum Rabi frequencies in the range of 10s of GHz. Such strong light-matter interaction produces an optical nonlinearity that is present even at single-photon level and is tunable at a very fast time-scale. This enables one to go beyond fundamental cavity quantum electrodynamics (CQED) studies and to employ such e ects for building practical information processing devices. My PhD work has focused on both fundamental physics of the coupled QD-nanocavity system, as well as on several proof-of-principle devices for low-power optical information processing based on this platform. We have demonstrated the e ects of photon blockade and photon-induced tunneling, which con rm the quantum nature of the coupled dot-cavity system. Using these e ects and the photon correlation measurements of light transmitted through the dot-cavity system, we identify the rst and second order energy manifolds of the Jaynes-Cummings ladder describing the strong coupling between the quantum dot and the cavity eld, and propose a new way to generate multi-Fock states with high purity. In addition, the interaction of the quantum dot with its semiconductor environment gives rise to novel phenomena unique to a solid state cavity QED system, namely phonon-mediated o -resonant dot-cavity coupling. We have employed this effect to perform cavity-assisted resonant quantum dot spectroscopy, which allows us to resolve frequency features far below the limit of a conventional spectrometer. Finally, the applications of such a coupled dot-cavity system in optical information processing including ultrafast, low power all-optical switching and electro-optic modulation are explored. With the light-matter interactions controlled at the most fundamental level, the nano-photonic devices we implemented on this platform operate at extremely low control powers and could achieve switching speeds potentially exceeding 10 GHz.
