Resumen
The contrast of an image can be degraded by the presence of background light and sensor noise. To overcome this degradation, quantum illumination protocols have been theorized that exploit the spatial correlations between photon pairs. Here, we demonstrate the first full-field imaging system using quantum illumination by an enhanced detection protocol. With our current technology, we achieve a rejection of background and stray light of up to 5.8 and also report an image contrast improvement up to a factor of 11, which is resilient to both environmental noise and transmission losses. The quantum illumination protocol differs from usual quantum schemes in that the advantage is maintained even in the presence of noise and loss. Our approach may enable laboratory-based quantum imaging to be applied to real-world applications where the suppression of background light and noise is important, such as imaging under low photon flux and quantum LIDAR.

Resumen
Impact of illumination on high-mobility dense 2D electron gas in selectively doped single GaAs quantum well with short-period AlAs/GaAs superlattice barriers at T=4.2 K in magnetic fields B<2 T has been studied. It was demonstrated that illumination at low temperatures gives rise to enhancement of electron density, mobility and quantum lifetime in studied heterostructures. The enhancement of quantum lifetime after illumination for single GaAs quantum well with modulated superlattice doping had been explained as consequence of decrease in effective concentration of remote ionized donors. Keywords: persistent photoconductivity, quantum lifetime, anisotropic mobility, superlattice barriers.

Classical target detection can suffer large error probabilities in noisy and lossy environments when noise photons are mistaken for signal photons reflected from an object. It has been shown theoretically that the correlation between entangled photons can be used to better discriminate between the signal photons reflected by an object and noise photons, thus reducing the probability of error [13, 15, 17, 7, 6]. This thesis presents the first experimental implementation of target detection enhanced by quantum illumination (QI). Nondegenerate, time entangled signal and idler beams are created through Type-O spontaneous parametric downconversion (SPDC). The signal is attenuated and combined with large levels of noise. The signal is phase modulated to improve the observation by shifting it from DC to 16 kHz. The return signal and idler are recombined in an optical parametric amplifier (OPA) which captures the phase correlation between the two beams. It is found that only 10% of the total signal and idler photons interact at the OPA due to the multi-mode nature of the SPDC emission which does not match the pump spatial mode and thus experience lower gains at the OPA. Considering only the power interacting at the OPA, the signal-to-noise ratio (SNR) of QI agrees with the theoretical model.

Quantum illumination is a paradigm for using entanglement to gain a performance advantage-in comparison with classical-state systems of the same optical power-over lossy, noisy channels that destroy entanglement. Previous work has shown how it can be used to defeat passive eavesdropping on a two-way Alice-to-Bob-to-Alice communication protocol, in which the eavesdropper, Eve, merely listens to Alice and Bob's transmissions. This thesis extends that work in several ways. First, it derives a lower bound on information advantage that Alice enjoys over Eve in the passive eavesdropping scenario. Next, it explores the performance of alternative practical receivers for Alice, as well as various high-order modulation formats for the passive eavesdropping case. Finally, this thesis extends previous analysis to consider how Alice and Bob can minimize their vulnerability to Eve's doing active eavesdropping, i.e., when she injects her own light into the channel.

Includes bibliographical references (page 67).
Secure communication based on quantum illumination (QI) provides high-speed direct communication in the presence of loss and noise and is secure against passive eavesdropping. Recently, the QI based communication protocol has been demonstrated in a fiber channel. In this thesis, we extend the QI secure communication protocol to a free-space propagation channel. Unlike a fiber channel, a free-space channel is susceptible to air turbulence. Because a single spatial mode of light is essential in the QI protocol, if the beam path is affected by air turbulence, the power and phase may fluctuate, which can affect the interferometric measurement performance of QI. In order to fix this issue, we have designed and implemented a servo system to stabilize the coupling of the free-space propagating beam into a single-mode fiber. The servo system utilizes the X and Y tilts of a single piezoelectrically driven mirror mount, together with a quadrant detector, to stabilize the beam location at the collimation optics of the free-space path. To demonstrate the QI-based secure communication with a free-space path, we use a heat source to simulate air turbulence. We have demonstrated that the free-space secure communication using quantum illumination is still possible in an environment with air fluctuation, by using a servo system to counteract the deleterious effect the effect from air turbulence. Without air tubulence, we have demonstrated that BERA ~~ 5.8 x 10-⁴ for a free-space channel implemented in the Bob-to-Alice path or Alice-to-Bob path with Ns ~~ 5.6 x 10--⁴. When we introduce a heat source at a known setting, the effective attenuation h for the Bob-to-Alice or Alice-to-Bob channel transmissivity is found to be 0.63. Without the servo system, BERA drops to 2.40 x 10-⁴ and 9.8 x 10-³ for the free-space Bob-to-Alice and Alice-to-Bob channels, respectively, for the same amount of Ns. With both heat source and the servo system on, we have successfully operated the QI-based secure communication protocol and obtained the same level of Alice's BER as that without the heat source.

Resumen
Approved for public release; distribution is unlimited
The terahertz (THz) region of the electromagnetic spectrum has not been fully utilized due to the lack of compact and efficient sources as well as detectors. This thesis aimed on characterizing a quantum cascade laser (QCL) beam and achieving high quality real-time THz imaging using a 160x120 pixel FLIR A20M microbolometer camera designed to operate in long wave infrared range. The FTIR spectroscopy of the QCL beam revealed that lasing could be achieved at 2.85 and 2.91 THz frequencies depending on the bias current. This behavior was analyzed using the longitudinal modes of the laser and found to correspond well with the experimental observations. Real-time imaging of concealed objects in transmission mode was accomplished using the silicon nitride-based microbolometer camera under illumination via the QCL with average power less than 1 mW. The larger extent of the object required the expansion of the narrow laser beam using a parabolic reflector and refocus on the camera using a second parabolic reflector. The standard Ge lens of the camera was replaced by a Tsurupica lens since the earlier lens was opaque to THz radiation. The real-time imaging can be extended to reflection mode as well as longer standoff distances using higher power THz lasers.

Resumen
The aim of this PhD project, also called “warm white light project”, is to propose an alternative solid state lighting device that works using the same principles of color-conversion WLEDs. The idea is to create a polymer based nanocomposite that could work as a transparent glass in off-mode and as a “lamp” in on-mode. The new concept is to spatially decouple the light source and the converters in order to avoid all the thermal problems that affect the current LEDs (in which the color is “generated” within the chip and the epoxy case). To do so, a blue LED, made of Indium gallium nitride (InGaN), is coupled to a bulk polymer nanocomposite sheet where the actual conversion of light takes place. For emitting white light it is necessary that the nanocomposite would not only convert partially the blue light into warmer colors (like yellow and red) but also diffuse the blue light outside in order to have a color mixing.

Resumen
This thesis is concerned with the characterisation, fabrication and testing of devices capable of generating and detecting terahertz (THz) radiation. Such devices are based on semiconductor photoconductors grown under low temperature (LT) conditions using the technique of Molecular Beam Epitaxy (MBE). The absorption of a pulsed or continuous wave (CW) signal by these structures in conjunction with the presence of an electric field generates photocurrent, which is fed into an antenna structure fabricated on the surface of the active layers. As a result of such a sequence, a THz signal is generated and radiated from the substrate side into free space. Therefore, the efficiency of the devices is determined by the characteristics of the photoconductors and the geometry of the designed antenna structures. The desired material characteristics are high absorption at the corresponding illumination wavelength, high dark resistivity, high electron mobility and sub picosecond carrier lifetime. The determination of these characteristics for all the structures grown in this work composes the characterisation part of the thesis. The fabrication part comprises of the design of several antenna structures with various geometrical characteristics, while the testing part consists of their evaluation as THz sources and detectors in a time-domain spectroscopy (TDS) system under pulsed excitation. To date, THz devices based on low temperature grown GaAs (LT-GaAs) photoconductors have been reported to be the most efficient. However, their operational wavelength, at 800 nm, requires very expensive and complex components spurring interests in solutions consisting of devices operating at longer wavelengths, where cheaper and simpler components exist. The most desirable and practical operational wavelength is the telecommunication one at 1.55 μm. Thus, the biggest challenge is the development of efficient devices operating at this illumination wavelength. In this work, devices operating at the very important wavelength of 1.55 μm as well as at the wavelengths of 1 μm and 800 nm are presented. The key findings for the long wavelength devices (1.55 μm) demonstrate photoconductors with ultrafast carrier lifetimes (~ 120 fs), high resistivity (> 105 Ω / sq), high mobility (> 1000 cm2 / Vs) and system responses with spectral range up to 3 THz and power-to-noise ratio of 60 dB. These characteristics are among the best ever reported for such material systems, making them efficient THz devices for various optoelectronic applications, especially for telecommunication laser-driven CW THz systems.

Resumen
Cette thèse propose une approche originale de la thématique du radar à illumination quantique en recourant à la théorie de l’information quantique pour étudier l’évolution des corrélations quantiques le long d’une chaîne radar. Ce mémoire propose d’abord un parallèle des différences et similitudes entre les théories du radar classique et du radar quantique en insistant sur les principes propres aux deux théories. Le radar à illumination quantique étudié utilise des paires de photons intriqués pour établir la présence ou l’absence d’un objet faiblement réfléchissant baigné dans un bruit thermique parasitant la détection. À partir de la mise en parallèle, les travaux se sont concentrés sur l’influence de l’environnement atmosphérique dans l’évolution de l’intrication du système de photons du radar et dans l’évolution des corrélations quantiques représentées par la discorde quantique. L’objectif des recherches était de montrer un lien entre la discorde quantique et la stratégie de détection binaire du radar quantique. Les résultats tendent à montrer ce lien même si des améliorations aux modèles composés pour l’étude seraient bienvenues. Cela permettrait notamment d’orienter la recherche vers des cas concrets pouvant bénéficier d’une application expérimentale du procédé d’illumination quantique
This thesis provides an original approach of the quantum illumination radar using the quantum information theory to study the evolution of quantum correlations in a radar system. We first propose a parallel between the classical radar theory and the quantum radar theory to determine similarities anf differences insisting on the last point. The quantum illumination radar uses pairs of entangled photons to detect the absence of the presence of a low-reflecting object into a bright thermal background that disturbs the detection. Using the parallel between the radar theories, research has been done on the atmospheric influence on the evolution of entanglement of the system of photons in the radar, and on the evolution of quantum correlations quantified by the quantum discord. The objective of research was to show a link between the quantum discord and the binary decision strategy of the quantum radar. Results suggest this link even if improvements should be required on the tested models. It should permit to study practical situations particularly if we think about a possible experiment on a quantum illumination protocol

Resumen
This PhD thesis is devoted to study electro-optic properties of Gemanium/Silicon-Germanium (Ge/SiGe) multiple quantum wells (MQWs) for light modulation, detection, and emission on Si platform. It reports the first development of high speed, low energy Ge/SiGe electro-absorption modulator in a waveguide configuration based on the quantum-confined Stark effect (QCSE), demonstrates the first Ge/SiGe photodiode with high speed performance compatible with 40 Gb/s data transmission, and realizes the first Ge/SiGe light emitting diode based on Ge direct gap transition at room temperature. Extensive DC and RF measurements were performed on each tested prototype, which was realized using the same epitaxial growth and fabrication process. Simple theoretical models were employed to describe experimental properties of the Ge/SiGe MQWs. The studies show that Ge/SiGe MQWs could potentially be employed as a new photonics platform for the development of a high speed optical link fully compatible with silicon technology.

In this study, we introduce photovoltaic effect first, we found that measured capacitance would increase and form a plat form after we illuminate GaAsN/GaAs quantum well schottky diode sample. Photovoltaic effect had been researched by the other study. The electric field would deplete the excess carriers which generated by illumination to form a photo current. The photo current would charge quantum well, and form a voltage drop across quantum well. Quantum well could store charges and hold a voltage drop that serves as a capacitive loading. In this study, we use two methods to obtain quantum well photo capacitance when we apply little bias (Schottky junction depletion region has not arrived quantum well). First, we apply C-V plot and I-V plot to calculate quantum well photo voltage drop and carriers which charged into quantum well respectively. Divide the carriers and voltage drop, we can obtain experiment photo capacitance. Second, we express quantum well photo capacitance as a parallel plate capacitor substitute charge Q by quantum well density of state and Fermi-Dirac distribution. Sovle the equation, we can obtain the simulated photo capacitance.

The electron emission properties of the EL2 defect state with (without) illumination in 2.2-ML(monolayer) InAs self-assembled quantum dots (QDs) containing an EL2 defect state is presented. Initially, the defect state is observed at the temperature dependence capacitance-voltage (C-V) profiling, leading to the faster electron emission rate with temperature increasing. The source of the EL2 defect state is studied by deep-level transient spectroscopy (DLTS) measurements. Moreover, we calculate the concentration of the EL2 defect state, which is compared with the doping background concentration of top GaAs layer. Under an energy illumination of 0.8 eV, the large capacitance produces, suggesting the electron emission rate of the EL2 defect state increasing. An expression of electron emission rate is dependent with the intensity of the excited light source and optical cross section. Furthermore, the electron occupancy probability is changed upon illumination. The DLTS measurement under illumination also shows the electron emission rate increasing. Finally, the electron-hole pairs produce in the QDs and defect states under illumination energy of 0.7-1.56 eV can explain the relationship between photocapacitance, photocurrent, and carrier radiative recombination. Furthermore, a simple rate equation can describe this phenomenon.

Resumen
The technological realm provides an unusually active laboratory not only for new ideas and products but also for the remarkable linguistic innovations that accompany and describe them. How else would words like qubit (a unit of quantum information), crowdsourcing (outsourcing to the masses), or in vitro meat (chicken and beef grown in an industrial vat) enter our language? In Virtual Words: Language on the Edge of Science and Technology, Jonathon Keats, author of Wired Magazine's monthly Jargon Watch column, investigates the interplay between words and ideas in our fast-paced tech-driven use-it-or-lose-it society. In 28 illuminating short essays, Keats examines how such words get coined, what relationship they have to their subject matter, and why some, like blog, succeed while others, like flog, fail. Divided into broad categories--such as commentary, promotion, and slang, in addition to scientific and technological neologisms--chapters each consider one exemplary word, its definition, origin, context, and significance. Examples range from microbiome (the collective genome of all microbes hosted by the human body) and unparticle (a form of matter lacking definite mass) to gene foundry (a laboratory where artificial life forms are assembled) and singularity (a hypothetical future moment when technology transforms the whole universe into a sentient supercomputer). Together these words provide not only a survey of technological invention and its consequences, but also a fascinating glimpse of novel language as it comes into being. No one knows this emerging lexical terrain better than Jonathon Keats. In writing that is as inventive and engaging as the language it describes, Virtual Words offers endless delights for word-lovers, technophiles, and anyone intrigued by the essential human obsession with naming.

Resumen
AbstractMetal halide perovskites have triggered a quantum leap in the photovoltaic technology marked by a humongous improvement in the device performance in a matter of just a few years. Despite their promising optoelectronic properties, their use in the photovoltaic sector remains restricted due to their inherent instability towards moisture. Here, we report a simple, cost-effective and highly efficient protection strategy that enables their use as photoelectrodes for photoelectrochemical hydrogen production while being immersed in water. A uniform coating of candle soot and silica is developed as an efficient hydrophobic coating that protects the perovskite from water while allowing the photogenerated electrons to reach the counter electrode. We achieve remarkable stability with photocurrent density above 1.5 mA cm−2 at 1 V versus saturated calomel electrode (SCE) for ~1 h under constant illumination. These results indicate an efficient route for the development of stable perovskite photoelectrodes for solar water splitting.

Resumen
Abstract The calculations of the preceding chapter display some of the inadequacies of the Einstein theory of interaction of light with atoms. The theory itself gives no prescription for computing the values of the A and B coefficients appropriate to a given atomic transition. For this one must look to the quantum-mechanical theory of transition probabilities. As light beams are generated by emission from atoms and measurements on light beams ultimately depend on the absorption of light by atoms, it is essential to cover the theory of the atomic interaction processes, even though the main interest of the book is the quantum nature of the light itself. More seriously, the Einstein theory is applicable only for broad-band illumination of the atom, where the energy in the incident light is distributed smoothly across the frequencies within the linewidth of the atomic transition. By contrast, many experiments with laser sources use light beams whose frequency distributions are much narrower than atomic transition linewidths.

Resumen
As the size of a material decreases to the nanoscale its properties become size-dependent. This is the world of nanoscience and nanotechnology. At the nanoscale the crystal structure may change and thermodynamic quantities such as the melting point also change. Changes in the catalytic activity and colour of nanoparticles suspended in a liquid indicate changes to the electronic structure. Quantum dots have discrete energy levels that can be modelled with the particle-in-a-box model. Excitons may be created in them using optical illumination, and their decay leads to fluorescence with distinct colours. The classical and quantum origins of magnetism are discussed. The origin of magnetoresistance in a ferromagnet is described and related to the exclusion principle. The origin of the giant magnetoresistance effect and its exploitation in nanotechnology is outlined.

Resumen
We design a feedback scheme that can be used to operate efficiently a microwave quantum-illumination device based on electro-optomechanical systems also in regimes in which photon losses would, otherwise, prevent to outperform the optimal classical illumination protocol with the same transmitted energy.
