Book excerpt: Quantum information is a fascinating field that studies situations in which information is encoded as quantum states. This encoding is affected by quantum physical effects (such as superposition or entanglement) and its study has led to exciting discoveries from both fundamental and applied perspectives. An interesting system within this field is a quantum light-matter interface, able to interface quantum states encoded in light and those encoded in matter. These systems can combine the long distance transmission advantage of photonic states with the storage and processing capabilities of matter states. The main goal of this thesis was to develop a quantum light-matter interface able to distribute the photonic state to other interfaces based on different platforms. This versatility could open new possibilities that combine the advantages of the different platforms. In this thesis we studied the challenges to make these hybrid connections possible and we performed two examples of such connections. Our quantum light-matter interface is based on a cloud of Rubidium atoms that are laser-cooled in a magneto-optical trap. We operate the atomic system using the Duan-Lukin-Cirac-Zoller scheme in order to generate pairs consisting on a single photon and an atomic collective spin excitation (so-called spin-wave). Spin-waves can later be mapped efficiently into a second single photon, which allows for synchronization capabilities. We use this scheme to generate different types of quantum states, such as heralded on-demand single photons and photonic qubits, photon-photon correlated states, or entanglement between photonic and atomic qubits. Firstly, we studied two capabilities needed in order to perform the mentioned hybrid connections: the frequency and temporal tunability of the photonic states. In the first one we studied the frequency conversion of the single photons paired with spin-waves in the atomic medium. We could convert their wavelength from 780 nm to 1550 nm using a nonlinear crystal waveguide, while still showing quantum statistics of the field. In the second one we showed a temporal tunability of the single photons with durations ranging from around 10 ns to 10 us. The studied statistics of the fields indicate that the photons are close to Fourier-transform-limited, allowing for photon bandwidth tunability. In the third work we studied the generation of a light-matter entangled state in which the photonic state is encoded as a time-bin qubit. Two key ingredients enabled this experiment: a magnetic-field-induced atomic dephasing that allows to create spin-waves in two distinguishable temporal qubit modes, and largely imbalanced Mach-Zehnder interferometers that enabled the qubit analysis. Photonic time-bin encoding has the advantages of low decoherence in optical fibers and direct suitability for frequency conversion. Finally, we took advantage of these studied capabilities in order to transfer photonic quantum states generated by our laser-cooled atomic system to two different types of light-matter interfaces. The first one was a laser-cooled Rubidium cloud able to transfer single photons into Rydberg excitations. We showed that the quantum statistics of our photonic fields are preserved after the Rydberg storage, which represents a first step for future studies of quantum nonlinear effects using the long range Rydberg interaction. The second one was a crystal doped with Praseodymium ions. In this work the photonic quantum state transfer happened between systems with different atomic species, being a truly hybrid example that was enabled by quantum frequency conversion. These results show a quantum light-matter interface where the properties of the photonic states can be tuned for an optimal interaction with other matter platforms. The proof-of-principle photonic quantum state transfers to the Rydberg and doped-crystal systems open the way to study new experiments that combine advantages of different platforms.

Book excerpt: I present in this thesis the design, implementation and measurement results of a narrowband quantum light source based on cavity-enhanced Parametric Down-Conversion (PDC). Spontaneous Parametric Down-Conversion (SPDC) is the workhorse in the field of optical quantum information and quantum computation, yet it is not suitable for applications where deterministic nonlinearities are required due to its low spectral brightness. By placing the nonlinear crystal inside a cavity, the spectrum of down-conversion is actively modified, such that all the non-resonant modes of down-conversion experience destructive interference, while the resonant mode sees constructive interference, resulting in great enhancement in spectral brightness. I design and construct such a cavity-enhanced down-conversion source with record high spectral brightness, making it possible to use cold atoms as the interaction medium to achieve large nonlinearity between photons. The frequency of the photons is tunable and their coherence time is measured to be on the order of 10 nanoseconds, matching the lifetime of the excited state of typical alkali atoms. I characterize extensively the output of the source by measuring the second-order correlation function, quantifying two-photon indistinguishability, performing quantum state tomography of entangled states, and showing different statistics of the source. The unprecedented long coherence time of the photon pairs has also made possible the encoding of quantum information in the time domain of the photons. I present a theoretical proposal of multi-dimensional quantum information with such long-coherence-time photons and analyze its performance with realistic parameter settings. I implement this proposal with the quantum light source I have built, and show for the first time that a qutrit can be encoded in the time domain of the single photons. I demonstrate the coherence is preserved for the qutrit state, thus ruling out any classical probabilistic explanation of the experimental data. Such an encoding scheme provides an easy access to multi-dimensional systems and can be used as a versatile platform for many quantum information and quantum computation tasks.

Book excerpt: The counter-intuitive aspects of quantum physics have been long illustrated by thought experiments, from Einstein's photon box to Schrödinger's cat. These experiments have now become real, with single particles - electrons, atoms, or photons - directly unveiling the strange features of the quantum. State superpositions, entanglement and complementarity define a novel quantum logic which can be harnessed for information processing, raising great hopes for applications. This book describes a class of such thought experiments made real. Juggling with atoms and photons confined in cavities, ions or cold atoms in traps, is here an incentive to shed a new light on the basic concepts of quantum physics. Measurement processes and decoherence at the quantum-classical boundary are highlighted. This volume, which combines theory and experiments, will be of interest to students in quantum physics, teachers seeking illustrations for their lectures and new problem sets, researchers in quantum optics and quantum information.

Book excerpt: Certain diatomic molecules are disposed to laser cooling in the way successfully applied to certain atoms and that ushered in a revolution in ultracold atomic physics, an identification first made at Los Alamos and which took root during this program. Despite their manipulation into numerous achievements, atoms are nonetheless mundane denizens of the quantum world. Molecules, on the other hand, with their internal degrees of freedom and rich dynamical interplay, provide considerably more complexity. Two main goals of this program were to demonstrate the feasibility of laser-cooling molecules to the same temperatures as laser-cooled atoms and introduce a means for collecting laser-cooled molecules into dense ensembles, a foundational start of studies and applications of ultracold matter without equivalence in atomic systems.

Book excerpt: Light and light based technologies have played an important role in transforming our lives via scientific contributions spanned over thousands of years. In this book we present a vast collection of articles on various aspects of light and its applications in the contemporary world at a popular or semi-popular level. These articles are written by the world authorities in their respective fields. This is therefore a rare volume where the world experts have come together to present the developments in this most important field of science in an almost pedagogical manner. This volume covers five aspects related to light. The first presents two articles, one on the history of the nature of light, and the other on the scientific achievements of Ibn-Haitham (Alhazen), who is broadly considered the father of modern optics. These are then followed by an article on ultrafast phenomena and the invisible world. The third part includes papers on specific sources of light, the discoveries of which have revolutionized optical technologies in our lifetime. They discuss the nature and the characteristics of lasers, Solid-state lighting based on the Light Emitting Diode (LED) technology, and finally modern electron optics and its relationship to the Muslim golden age in science. The book’s fourth part discusses various applications of optics and light in today's world, including biophotonics, art, optical communication, nanotechnology, the eye as an optical instrument, remote sensing, and optics in medicine. In turn, the last part focuses on quantum optics, a modern field that grew out of the interaction of light and matter. Topics addressed include atom optics, slow, stored and stationary light, optical tests of the foundation of physics, quantum mechanical properties of light fields carrying orbital angular momentum, quantum communication, and Wave-Particle dualism in action.

Book excerpt: The primary focus of this thesis is to theoretically describe nanokelvin experiments in cold atomic gases, which offer the potential to revolutionize our understanding of strongly correlated many-body systems. The thesis attacks major challenges of the field: it proposes and analyzes experimental protocols to create new and interesting states of matter and introduces theoretical techniques to describe probes of these states. The phenomena considered include the fractional quantum Hall effect, spectroscopy of strongly correlated states, and quantum criticality, among others. The thesis also clarifies experiments on disordered quantum solids, which display a variety of exotic phenomena and are candidates to exhibit so-called "supersolidity." It collects experimental results and constrains their interpretation through theoretical considerations. This Doctoral Thesis has been accepted by Cornell University, Ithaca, USA.
