Available in PDF, EPUB and Kindle. Book excerpt: Discovering dark matter is one of the great challenges in contemporary physics. Successive generations of experiments -- each more impressive and sophisticated than the last -- have all failed to uncover dark matter's most basic properties. We have abundant evidence suggesting that dark matter exists, but we do not know the identity of the particle(s) that make up dark matter (let alone their mass, lifetime, spin, or coupling to other particles). In spite of decades of fruitless searching, the experimental physics community has not given up on identifying dark matter, since the payoff of a successful detection would be enormous. Characterizing dark matter would provide the first-ever opportunity to study a particle outside the Standard Model, and probing the structure of the Milky Way's dark matter halo would open up an entirely new avenue to study astrophysics and cosmology. These exciting prospects have motivated ever larger and more costly detectors, which acquire years' worth of data in order to accumulate sufficient statistics. Because of the intensive effort that has already been dedicated to finding dark matter, it is challenging to make progress without an expensive and large-scale experiment. This thesis describes a small part of the ongoing effort to make dark matter searches more tractable by adopting the techniques of quantum information science. Quantum information science has developed by leaps and bounds over the past decade, driven largely by the desire to build a quantum computer that exceeds the performance of any realistic classical computer. Although an unequivocal demonstration of such a "quantum speedup" remains elusive, the quantum information community has made impressive progress in preparing, manipulating, and detecting quantum states of light and matter. Leveraging such non-classical states in a dark matter detector allows it to greatly exceed the sensitivity of an equivalent, purely classical detector. A quantum speedup (in sensing, rather than computing) would dramatically reduce the size and cost of a useful dark matter detector. However, quantum states are fragile and difficult to manipulate, so substantial effort is needed to fully realize any non-classical advantage. This thesis is divided into two parts. In the first part, I design, build, and characterize the DM Radio Pathfinder, a modestly-scaled dark matter detector. I use the Pathfinder to set the best laboratory limits on a particular dark matter candidate particle, the hidden photon. Although the detector uses many techniques relevant to quantum information science, including cryogenics and sensitive superconducting circuits, it is a classical experiment which does not achieve any quantum speedup. In the second part of the thesis, I propose the RQU, a superconducting circuit that could plausibly achieve a quantum speedup in a dark matter experiment similar to the Pathfinder. I design and fabricate prototype RQUs and characterize their properties in several experiments. Finally, I propose a realistic path towards using RQUs to achieve a quantum speedup in a real dark matter detector.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents the basics and applications of superconducting devices in quantum optics. Over the past decade, superconducting devices have risen to prominence in the arena of quantum optics and quantum information processing. Superconducting detectors provide unparalleled performance for the detection of infrared photons in quantum cryptography, enable fundamental advances in quantum optics, and provide a direct route to on-chip optical quantum information processing. Superconducting circuits based on Josephson junctions provide a blueprint for scalable quantum information processing as well as opening up a new regime for quantum optics at microwave wavelengths. The new field of quantum acoustics allows the state of a superconducting qubit to be transmitted as a phonon excitation. This volume, edited by two leading researchers, provides a timely compilation of contributions from top groups worldwide across this dynamic field, anticipating future advances in this domain.
Download or read book Testing and Characterization of SuperCDMS Dark Matter Detectors written by and published by . This book was released on 2014 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Cryogenic Dark Matter Search (SuperCDMS) relies on collection of phonons and charge carriers in semiconductors held at tens of milliKelvin as handles for detection of Weakly Interacting Massive Particles (WIMPs). This thesis begins with a brief overview of the direct dark matter search (Chapter 1) and SuperCDMS detectors (Chapter 2). In Chapter 3, a 3He evaporative refrigerator facility is described. Results from experiments performed in-house at Stanford to measure carrier transport in high-purity germanium (HPGe) crystals operated at sub-Kelvin temperatures are presented in Chapter 4. Finally, in Chapter 5 a new numerical model and a time-domain optimal filtering technique are presented, both developed for use with superconducting Transition Edge Sensors (TESs), that provide excellent event reconstruction for single particle interactions in detectors read out with superconducting W-TESs coupled to energy-collecting films of Al. This thesis is not intended to be read straight through. For those new to CDMS or dark matter searches, the first two chapters are meant to be a gentle introduction for experimentalists. They are by no means exhaustive. The remaining chapters each stand alone, with different audiences.
Download or read book Superconducting and Low temperature Particle Detectors written by European Materials Research Society. Meeting and published by North Holland. This book was released on 1989 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: As demonstrated by the contributions in this volume, the domain of superconducting and low-temperature devices is in a rapidly expanding phase. Interactions between materials sciences, low-temperature physics, astrophysics, nuclear and particle physics have provided the incentive for new experiments, which could ultimately record such rare interactions as double beta decay, neutrino scattering, or collisions of the elusive dark matter halo particles. The theoretical and experimental improvements achieved during the last year have been impressive. Detection of 60 keV resolution with a non-zero spin material as a target seems therefore realizable in the near future. Similarly, impressive achievements on ballistic phonons detection and superheated superconducting detectors have been presented, together with reliable techniques for developing ultra low noise electronics required by these ambitious experiments. Apart from the contributions presented during the symposium, the two original papers by Niinikoski proposing the use of bolometers as particle detectors have been included in this volume. These papers, despite their current interest, have never been published before.

This book was released on 2019-04-27 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quantum mechanics, the subfield of physics that describes the behavior of very small (quantum) particles, provides the basis for a new paradigm of computing. First proposed in the 1980s as a way to improve computational modeling of quantum systems, the field of quantum computing has recently garnered significant attention due to progress in building small-scale devices. However, significant technical advances will be required before a large-scale, practical quantum computer can be achieved. Quantum Computing: Progress and Prospects provides an introduction to the field, including the unique characteristics and constraints of the technology, and assesses the feasibility and implications of creating a functional quantum computer capable of addressing real-world problems. This report considers hardware and software requirements, quantum algorithms, drivers of advances in quantum computing and quantum devices, benchmarks associated with relevant use cases, the time and resources required, and how to assess the probability of success.

Download or read book Galileo Unbound written by David D. Nolte and published by Oxford University Press. This book was released on 2018-07-12 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Galileo Unbound traces the journey that brought us from Galileo's law of free fall to today's geneticists measuring evolutionary drift, entangled quantum particles moving among many worlds, and our lives as trajectories traversing a health space with thousands of dimensions. Remarkably, common themes persist that predict the evolution of species as readily as the orbits of planets or the collapse of stars into black holes. This book tells the history of spaces of expanding dimension and increasing abstraction and how they continue today to give new insight into the physics of complex systems. Galileo published the first modern law of motion, the Law of Fall, that was ideal and simple, laying the foundation upon which Newton built the first theory of dynamics. Early in the twentieth century, geometry became the cause of motion rather than the result when Einstein envisioned the fabric of space-time warped by mass and energy, forcing light rays to bend past the Sun. Possibly more radical was Feynman's dilemma of quantum particles taking all paths at once — setting the stage for the modern fields of quantum field theory and quantum computing. Yet as concepts of motion have evolved, one thing has remained constant, the need to track ever more complex changes and to capture their essence, to find patterns in the chaos as we try to predict and control our world.
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.

Download or read book Visualising the Charge and Cooper Pair Density Waves in Cuprates written by Stephen Edkins and published by Springer. This book was released on 2017-08-31 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis reports on the use of scanning tunnelling microscopy to elucidate the atomic-scale electronic structure of a charge density wave, revealing that it has a d-symmetry form factor, hitherto unobserved in nature. It then details the development of an entirely new class of scanned probe: the scanning Josephson tunnelling microscope. This scans the Josephson junction formed between a cuprate superconducting microscope tip and the surface of a cuprate sample, thereby imaging the superfluid density of the sample with nanometer resolution. This novel method is used to establish the existence of a spatially modulated superconducting condensate, something postulated theoretically over half a century ago but never previously observed.
