Quantum computers oﬀer a credible challenge to the strong church-turing thesis, as there exist eﬃcient algorithms for which there are no classical counterparts. Consequently, the quantum complexity-theoretic church-turing thesis states: a quantum turing machine can efficiently simulate any realistic model of computation eugene eberbach and peter wegner claim that the church-turing thesis is sometimes interpreted too broadly, stating the broader assertion that algorithms precisely capture what can be computed is invalid. Feynman's thesis or the principle of least action in.
Topics in quantum computing there are a variety of topics that traditionally are covered in a quantum computing course i list some of this on this website to give a first impression of what is required of a quantum computing course. Communication (qc) schemes, such as quantum dense coding , quantum telepor- tation , and a quantum repeater [47, 46, 49], which is at the heart of long distance qc the experimental work presented in this diploma thesis was performed at two uni. Logic synthesis for fault-tolerant quantum computers a dissertation submitted to the department of electrical engineering and the committee on graduate studies.
A study of fluorescent nanoparticles: quantum dots and silica dots a thesis presented to the faculty of the graduate school of cornell university. This thesis focuses on controlling electron spins in gaas quantum dots  the electron spin is the simplest non-trivial quantum system, described by a two-dimensional hilbert. Abstract this thesis is an attempt to reconstruct the conceptual foundations of quantum mechanics first, we argue that the wave function in quantum mechanics is a description of random. Quantum dot structures are also intensely studied as promising candidates in the realization of quantum computing applications the main work of this thesis comprises a theoretical study of an experimentally.

Quantum signal processing (qsp) as formulated in this thesis, borrows from the formalism and principles of quantum mechanics and some of its interesting axioms and constraints, leading to a novel paradigm for signal processing with applications in areas ranging from frame theory, quantization and sampling methods to detection, parameter estimation, covariance shaping and multiuser wireless. It also sheds new light on fundamental issues like the interpretation of quantum theory because of its new overall space-time viewpointthe present volume includes feynman's princeton thesis, the related review article space-time approach to non-relativistic quantum mechanics [reviews of modern physics 20 (1948), 367-387], paul dirac's. Abstract in this phd thesis i investigate the occurrence of quantum coherences and their consequences in biological systems i consider both ﬁnite (spin) and.

In this contribution, the thesis that quantum mechanics is a powerful tool for explain- ing the characteristics of biological systems will be defended and some (speculative, at the moment) lines of research will be suggested. Quantum dot spins and microcavities for quantum information processing a dissertation submitted to the department of applied physics and the committee on graduate studies.

A new theory explains the seemingly irreversible arrow of time while yielding insights into entropy, quantum computers, black holes, and the past-future divide. Quantum systems, namely those that appear resistant to quantum attacks we argue, however, that the attacks considered in prior works model only the near future, where the attacker may be equipped with a quantum computer, but the end-users implementing the protocols are still running classical devices. Lar interpretation of quantum theory which, although not representative of the more careful formulations of some writers, is the most common form encountered in textbooks and university lectures on the subject. This thesis describes the development of circuit quantum electrodynamics (qed), architecture for studying quantum information and quantum optics in circuit qed a superconducting qubit.
