Book Synopsis Ultrafast Manipulation of Single Photons Using Dispersion and Sum-frequency Generation by : John Matthew Donohue
Download or read book Ultrafast Manipulation of Single Photons Using Dispersion and Sum-frequency Generation written by John Matthew Donohue and published by . This book was released on 2016 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: Single photons provide a natural platform for quantum communication and quantum networking, as they can be entangled in many degrees of freedom and maintain coherence over long-distance links. However, while their minimal interactions with the environment isolate them from detrimental noise, it can make them difficult to measure and manipulate. In particular, manipulation on the ultrafast timescale is necessary to fully exploit the energy-time (or spectral) photonic degree of freedom. Full control over the spectral properties of single photons is key to many quantum technologies and opens the door to natural high-dimensional quantum encodings. In this thesis, we theoretically and experimentally examine the use of nonlinear optical processes mediated by strong laser pulses as a method to control the spectral properties of ultrafast single photons. By mixing single-photon pulses with strong escort pulses that have been shaped through dispersion in a nonlinear crystal, the shape of the escort is imprinted on the photon, resulting in a custom-tailored upconverted pulse. We theoretically examine this process for quadratic spectral phases and show that it has the potential to be simultaneously effective and efficient for the customization of single-photon spectral waveforms, and can be performed in an entanglement-conserving manner. We then experimentally demonstrate the range of this technique through three applications. First, we show that sum-frequency generation with shaped pulses can be used to coherently measure time-bin encoded photons with bin separations on the order of picoseconds, well below the timing resolution of our detectors. Secondly, we show that this technique can be adapted to convert a train of pulses to a frequency comb, which can be read out in a straightforward manner using diffraction-based spectrometry. We also show here that this process can be performed in a polarization-maintaining fashion, and demonstrate that entanglement with a partner photon is conserved with high fidelity. Finally, we show that this process can be viewed as a time lens, which modulates a temporal waveform in an analogous fashion to a lens focusing a beam of light. We apply the time lens to a photon from an energy-time entangled pair, and show negative magnification of the joint spectrum through a reversal of the spectral correlations. Such processes could find application in quantum state engineering and high-speed single-photon measurement.
Book Synopsis Single Photon Generation and Manipulation with Semiconductor Quantum Dot Devices by : Lorenzo De Santis

This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quantum phenomena can nowadays be engineered to realize fundamentally new applications. This is the field of quantum technology, which holds the promise of revolutionizing computation, communication and metrology. By encoding the information in quantum mechanical systems, it appears to be possible to solve classically intractable problems, achieve absolute security in distant communications and beat the classical limits for precision measurements. Single photons as quantum information carriers play a central role in this field, as they can be easily manipulated and can be used to implement many quantum protocols. A key aspect is the interfacing between photons and matter quantum systems, a fundamental operation both for the generation and the readout of the photons. This has been driving a lot of research toward the realization of efficient atom-cavity systems, which allows the deterministic and reversible transfer of the information between the flying photons and the optical transition of a stationary atom. The realization of such systems in the solid-state gives the possibility of fabricating integrated and scalable quantum devices. With this objective, in this thesis work, we study the light-matter interface provided by a single semiconductor quantum dot, acting as an artificial atom, deterministically coupled to a micropillar cavity. Such a device is shown to be an efficient emitter and receiver of single photons, and is used to implement basic quantum functionalities.First, under resonant optical excitation, the device is shown to act as a very bright source of single photons. The strong acceleration of the spontaneous emission in the cavity and the electrical control of the structure, allow generating highly indistinguishable photons with a record brightness. This new generation of single photon sources can be used to generate path entangled NOON states. Such entangled states are important resources for sensing application, but their full characterizatiob has been scarcely studied. We propose here a novel tomography method to fully characterize path entangled N00N state and experimentally demonstrate the method to derive the density matrix of a two-photon path entangled state. Finally, we study the effect of the quantum dot-cavity device as a non-linear filter. The optimal light matter interface achieved here leads to the observation of an optical nonlinear response at the level of a single incident photon. This effect is used to demonstrate the filtering of single photon Fock state from classical incident light pulses. This opens the way towards the realization of efficient photon-photon effective interactions in the solid state, a fundamental step to overcome the limitations arising from the probabilistic operations of linear optical gates that are currently employed in quantum computation and communication.
Book Synopsis Generation and Manipulation of Nonclassical Photon Sources in Nonlinear Processes by : Zhi-Yuan Zhou
Download or read book Generation and Manipulation of Nonclassical Photon Sources in Nonlinear Processes written by Zhi-Yuan Zhou and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nonclassical photon sources are key components in quantum information science and technology. Here, the basic principles and progresses for single photon generation and their further manipulation based on second- or third-order nonlinear processes in various degrees of freedom are briefly reviewed and discussed. Based on spontaneous parametric down-conversion and spontaneous four-wave mixing, various nonlinear materials such as quasi-phase-matching crystals, dispersion-shifted fibers, and silicon-on-insulator waveguides are used for single photon generation. The kinds of entanglement generated include polarization, time-energy, time-bin, and orbital angular momentum. The key ingredient for photon pair generation in nonlinear processes is described and discussed. Besides, we also introduce quantum frequency conversion for converting a single photon from one wavelength to another wavelength, while keeping its quantum properties unchanged. Finally, we give a comprehensive conclusion and discussion about future perspectives for single photon generation and manipulation in nonlinear processes. This chapter will provide an overview about the status, current challenge, and future perspectives about single photon generation and processing in nonlinear processes.

This book was released on 2006-12-29 with total page 941 pages. Available in PDF, EPUB and Kindle. Book excerpt: This important volume contains selected papers and extensive commentaries on laser trapping and manipulation of neutral particles using radiation pressure forces. Such techniques apply to a variety of small particles, such as atoms, molecules, macroscopic dielectric particles, living cells, and organelles within cells. These optical methods have had a revolutionary impact on the fields of atomic and molecular physics, biophysics, and many aspects of nanotechnology.In atomic physics, the trapping and cooling of atoms down to nanokelvins and even picokelvin temperatures are possible. These are the lowest temperatures in the universe. This made possible the first demonstration of Bose-Einstein condensation of atomic and molecular vapors. Some of the applications are high precision atomic clocks, gyroscopes, the measurement of gravity, cryptology, atomic computers, cavity quantum electrodynamics and coherent atom lasers.A major application in biophysics is the study of the mechanical properties of the many types of motor molecules, mechanoenzymes, and other macromolecules responsible for the motion of organelles within cells and the locomotion of entire cells. Unique in vitro and in vivo assays study the driving forces, stepping motion, kinetics, and efficiency of these motors as they move along the cell's cytoskeleton. Positional and temporal resolutions have been achieved, making possible the study of RNA and DNA polymerases, as they undergo their various copying, backtracking, and error correcting functions on a single base pair basis.Many applications in nanotechnology involve particle and cell sorting, particle rotation, microfabrication of simple machines, microfluidics, and other micrometer devices. The number of applications continues to grow at a rapid rate.The author is the discoverer of optical trapping and optical tweezers. With his colleagues, he first demonstrated optical levitation, the trapping of atoms, and tweezer trapping and manipulation of living cells and biological particles.This is the only review volume covering the many fields of optical trapping and manipulation. The intention is to provide a selective guide to the literature and to teach how optical traps really work.

Book Synopsis Exploring the Quantum by : Serge Haroche
Download or read book Exploring the Quantum written by Serge Haroche and published by OUP Oxford. This book was released on 2006-08-11 with total page 616 pages. Available in PDF, EPUB and Kindle. 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 Synopsis Exploring Quantum Foundations with Single Photons by : Martin Ringbauer
Download or read book Exploring Quantum Foundations with Single Photons written by Martin Ringbauer and published by Springer. This book was released on 2017-08-21 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis uses high-precision single-photon experiments to shed new light on the role of reality, causality, and uncertainty in quantum mechanics. It provides a comprehensive introduction to the current understanding of quantum foundations and details three influential experiments that significantly advance our understanding of three core aspects of this problem. The first experiment demonstrates that the quantum wavefunction is part of objective reality, if there is any such reality in our world. The second experiment shows that quantum correlations cannot be explained in terms of cause and effect, even when considering superluminal influences between measurement outcomes. The final experiment in this thesis demonstrates a novel uncertainty relation for joint quantum measurements, where the textbook relation does not apply.
