Efficient characterization, calibration, and correction of quantum information processors
No full textThe key challenge to useful quantum information processing is the deleterious effects of noise on intricate and fragile quantum states that are extraordinarily sensitive to environmental variations. The problem of quantum noise will be surmounted by quantum computer engineering. I propose a three step approach to the engineering problem 1) understand the noise and its nature, 2) remove all controllable sources of errors, and 3) correct for uncontrollable sources of error, ie., characterize, calibrate, and correct which are the three C's in the title of this thesis and form the three core parts of this work. In order to produce useful techniques, I have made great efforts to design an approach that is efficient in both classical and quantum computational resources.
Characterization concerns the definition and estimation of quantum noise models. A complete tomographic theory, such as that provided by gate set tomography, is theoretically useful, but efficiency constraints motivate reduced protocols such as phase estimation. Calibration deals with techniques to control a quantum processor and minimize its operational error. For this purpose, I adapt the celebrated ``linear, quadratic, Gaussian''(LQG) control of classical theory in the context of quantum calibration for the first time. LQG is the optimal control algorithm when model assumptions are met. Correction removes any remaining error, which is usually incoherent sources that cannot be corrected for with optimal classical control. I introduce a novel metric of code performance that can be used to identify optimal codes for efficient correction of errors under non-uniform noise distributions. The techniques presented in this work address foundational issues in quantum computer engineering
Comparing GARCH models for gold price data, using a statistical loss function approach and an option pricing approach
No full textDerivative instruments that rely on the price of gold are traded in large volumes. A significant number of these instruments are influenced by the volatility of gold price movements. Hence, it is important to understand the volatility of this commodity when developing successful trading and hedging strategies. In this thesis, use is made of various GARCH models that are evaluated using both in-sample and out-of-sample criteria

Controlling Quantum Systems for Quantum Information Processing
No full textFor several decades it has been appreciated that quantum computers hold incredible promise to perform calculations intractable to classical computation. However, this promise has be slow to realize. Dozens of quantum systems are currently being investigated for use in quantum information processing - none of which have yet demonstrated algorithms involving more than a handful of qubits and it remains unclear which, if any, of these systems will ultimately compose a scalable, robust quantum information processing architecture. In this thesis we employ analytical, optimal and algebraic control techniques to evaluate various quantum systems for their potential use in quantum information processing. In doing so, we have additionally identified several novel characterization procedures capable of probing both the coherent and incoherent dynamics of quantum systems. The first part of this thesis discusses work motivated by attempts to utilize donor qubits in silicon as quantum bits. We first propose a measurement of the state of a single donor electron spin using two-dimensional electron gas of a field-effect transistor and electrically detected magnetic resonance. We analyze the potential sensitivity of this measurement and show that it is a quantum nondemolition measurement of an electron-encoded state. We then present the first of two novel qubit characterization procedures. We consider the problem of rapidly characterizing a large number of similarly prepared qubits using techniques from optimal experiment design. All qubits are assumed to evolve according to the same physical processes, though the Hamiltonian parameters may vary from device to device - an inevitability in solid state qubits. We use the Cram\'er-Rao bound on the variance of a point estimator to construct the optimal series of experiments to estimate these free parameters, and present a complete analysis of the optimal experimental configuration. Though applied to dipole- and exchange-coupled qubits, this technique is widely applicable to other systems. The second part of the thesis discusses the role that control can play in measuring and mitigating noise in qubit systems. Our first result describes a method for quickly simulating the effects of arbitrary markovian noise on qubit systems through the use of a numerically optimized, multi-state Markovian fluctuator. This ability to rapidly simulate the noisy qubit evolution allows us to compute control sequences capable of maximally decoupling the qubit from the noise source. We then introduce the second characterization procedure of the these, showing that a single measurable and controllable qubit may act as a spectrometer of dephasing noise. We show that the formalism of dynamical decoupling can be used to estimate the short-time correlation function of the noise source, while long time correlations may be estimated by a very simple series of free evolution experiments. This technique is applicable to the wide range of physical implementations which suffer from dephasing noise.The final part of this thesis demonstrates that trapped neutral atoms may be utilized for the robust simulation of complex systems exhibiting a topological phase. We present a method to simulate the toric code Hamiltonian stroboscopically, and demonstrate that our technique preserves the ground state degeneracy . Furthermore, we introduce a dissipative mechanism allowing for thermalization of the system to a finite temperature or direct cooling to the ground state manifold

An Exploratory Investigation of Marital Role Expectations and their Relationships to Perceived Parent-Child Relations and Perceived Family Integration
No full textFifty-one male and 57 female college undergraduate students enrolled in an introductory psychology course responded to the Roe-Siegelman PCR Questionnaire, a modified form of Tharp's (1963b) Marital Role Expectation Form (MRE), and a Family Integration Scale as fulfillment of research participation requirements. Previous research had indicated that generally children who experienced love and warmth in their childhood home had marital role expectations of friendliness, spontaneity, adaptability, trust, responsibility, and leadership, while those who experienced rejecting and neglecting parental behaviors were more likely to have expectations of being seclusive, guilty, hostile, rigid, mistrustful, and irresponsible

An exploration of racial identity, perceived racism, and religious orientation as predictors of cultural mistrust in African Americans
No full texttextCenturies of overt and covert segregation, oppression and discrimination against persons of African ancestry in America by their white counterparts have conditioned this marginalized group to be mistrustful of their relations with white Americans. This response, known as cultural mistrust, significantly contributes to negative help-seeking attitudes and underutilization of mental health services because the majority of practitioners are white (Grier and Cobbs, 1968; Whaley, 2001). This report will use multiple regression statistical analysis to explore racial identity, perceived racism, and religious orientation as predictors of cultural mistrust to propose ways practitioners can increase African-American utilization of mental health services. Gender differences in cultural mistrust will also be explored.Educational Psycholog
Assessment of the Digital Divide: Barrier to Health Communication Dissemination
No full textIn 1984 the U.S. Department of Health and Human Services reports that while there is progress in improving the overall health of the general public, there is evidence of significant disparities in the overall health of selected racial minority groups. Empirical evidence supports that socioenvironment is a primary determinant of individual health outcomes and is a factor in the health outcomes for these targeted groups. Subsequent epidemiologic studies link access and substandard health care as prevalent in poor and minority communities. Federal, philanthropic, and advocacy organizations responded by organizing to eliminate racial and ethnic disparities in the U.S. One tool that has gained widespread attention is the expansion of the Internet as a tool for communication of health information to improve overall health outcomes. Research shows that characteristically, groups experiencing the greatest health care disparities are the same as those without access to computers and Internet services. Projects to reduce this trend are currently being piloted and are showing progress in confronting this problem.Master of Public Healt
Southern Thailand: from conflict to negotiations?
No full textSummary: In this Analysis, University of Leeds professor Duncan McCargo argues that the recent Malaysian-backed Southern Thai peace initiative has now run into some serious problems. He argues that despite its various shortcomings the initiative is still worthy of support, since it has gained far more traction that any previous attempts to address the decade-long insurgency. Thailand needs to maintain focus on the southern conflict despite its current preoccupation with a national-level political crisis that threatens to topple the government of Yingluck Shinawatra.
Key findings
The conflict in Southern Thailand is one of Asia’s most serious insurgencies, with over 6,000 dead over the last 10 years.
The Malaysian government sponsored negotiations represents the best hope for reaching a political settlement and bringing peace to the region.
However, both sides need to show greater commitment to the negotiations, introducing new structures and procedures
