Abstract:
Quantum effects can enhance information-processing capabilities and speed up the solution of certain computational problems. Whether a quantum advantage can be rigorously proven in some setting or demonstrated experimentally using near-term devices is the subject of active debate. We show that parallel quantum algorithms running in a constant time period are strictly more powerful than their classical counterparts; they are provably better at solving certain linear algebra problems associated with binary quadratic forms. Our work gives an unconditional proof of a computational quantum advantage and simultaneously pinpoints its origin: It is a consequence of quantum nonlocality. The proposed quantum algorithm is a suitable candidate for near-future experimental realizations, as it requires only constant-depth quantum circuits with nearest-neighbor gates on a two-dimensional grid of qubits (quantum bits).

Abstract:
We study the advantage of pure-state quantum computation without entanglement over classical computation. For the Deutsch-Jozsa algorithm we present the \emph{maximal} subproblem that can be solved without entanglement, and show that the algorithm still has an advantage over the classical ones. We further show that this subproblem is of greater significance, by proving that it contains all the Boolean functions whose quantum phase-oracle is non-entangling. For Simon's and Grover's algorithms we provide simple proofs that no non-trivial subproblems can be solved by these algorithms without entanglement.

Abstract:
Quantum technology promises to revolutionize how we learn about the physical world. An experiment that processes quantum data with a quantum computer could have substantial advantages over conventional experiments in which quantum states are measured and outcomes are processed with a classical computer. We proved that quantum machines could learn from exponentially fewer experiments than the number required by conventional experiments. This exponential advantage is shown for predicting properties of physical systems, performing quantum principal component analysis, and learning about physical dynamics. Furthermore, the quantum resources needed for achieving an exponential advantage are quite modest in some cases. Conducting experiments with 40 superconducting qubits and 1300 quantum gates, we demonstrated that a substantial quantum advantage is possible with today’s quantum processors.

Abstract:
La physique quantique a apporté une révolution conceptuelle quant à la nature de notre monde et apporte aujourd’hui une révolution technologique. En effet, l’utilisation de l’information quantique promet des applications surclassant les machines actuelles, dites classiques. La théorie de l’information quantique en variable continue porte sur l’étude des possibilités qu’offre l’encodage de l’information dans des degrés de liberté continus de systèmes quantiques. Mathématiquement, cette théorie étend l’étude de l'information quantique aux états quantiques dans des espaces de Hilbert de dimension infinie. Elle offre des perspectives différentes de l’information quantique en variable discrète et est notamment adaptée à la description des états quantiques de lumière. L’optique quantique est ainsi une plateforme expérimentale naturelle pour développer des applications quantiques en variable continue. La thèse s’articule autour de trois questions principales : d’où provient l’avantage quantique, c est-à-dire la capacité des machines quantiques à surclasser les machines classiques ? Comment s assurer du bon fonctionnement d une machine quantique ? Quels avantages peut-on tirer de l'utilisation de l’information quantique ? Ces trois questions sont au cœur du développement des technologies quantiques, et nous y apportons plusieurs réponses dans le cadre de la théorie de l’information quantique en variable continue et de l’optique quantique linéaire
Quantum physics has led to a revolution in our conception of the nature of our world and is now bringing about a technological revolution. The use of quantum information promises indeed applications that outperform those of today's so-called classical devices. Continuous variable quantum information theory refers to the study of quantum information encoded in continuous degrees of freedom of quantum systems. This theory extends the mathematical study of quantum information to quantum states in Hilbert spaces of infinite dimension. It offers different perspectives compared to discrete variable quantum information theory and is particularly suitable for the description of quantum states of light. Quantum optics is thus a natural experimental platform for developing quantum applications in continuous variable. This thesis focuses on three main questions: where does a quantum advantage, that is, the ability of quantum machines to outperform classical machines, come from? How to ensure the proper functioning of a quantum machine? What advantages can be gained in practice from the use of quantum information? These three questions are at the heart of the development of future quantum technologies and we provide several answers within the frameworks of continuous variable quantum information and linear quantum optics

In this thesis, we examine the advantages that quantum strategies afford in communication-limited games. Inspired by the card game blackjack, we particularly focus on cooperative, two-party sequential games in which a single classical bit of communication is allowed from the first-mover to the late-mover. Within this setting, optimal usage of quantum entanglement is explored, and conditions of quantum advantage over classical strategies are examined. Furthermore, theoretical, computational, and experimental techniques are presented that can be useful in the analysis and implementation of quantum strategies in these types of games.

Abstract:
The monograph is devoted to piecewise linear and generalized functions. They are widely used in various fields of research: in the theory of signal transmission and transformation, quantum field theory, control theory, problems of nonlinear dynamics, structural mechanics, semiconductor theory, economic applications, medicine, description of impulse effects and many others. When creating mathematical models, in some cases it is necessary to approximate these functions using analytical expressions, but not in the form of linear combinations, as in known methods, but in the form of attachments, compositions, using recursive sequences. The considered methods are devoid of the disadvantages of Fourier series and have advantages over other approximation methods. The developed approximation methods help to understand the meaning and content of generalized functions and their derivatives, and contribute to the conscious application of these functions in mathematical modeling problems. These methods can be used in a wide range of applied research, from medicine to quantum electronics. The theoretical material is illustrated by a large number of practical examples from a wide variety of applied fields. The fundamentals of the developed macroeconomic theory with impulse, shock, spasmodic characteristics and other types of rapidly changing processes are presented. For mathematicians, students and teachers, and specialists working in applied research fields.

Full text
Abstract:
Quantum Computing: From Alice to Bob provides a distinctive and accessible introduction to the rapidly growing fields of quantum information science (QIS) and quantum computing (QC). The book is designed for undergraduate students and upper-level secondary school students with little or no background in physics, computer science, or mathematics beyond secondary school algebra and trigonometry. While broadly accessible, the book provides a solid conceptual and formal understanding of quantum states and entanglement—the key ingredients in quantum computing. The authors give detailed treatments of many of the classic quantum algorithms that demonstrate how and when QC has an advantage over classical computers. The book provides a solid explanation of the physics of QC and QIS and then weds that knowledge to the mathematics of QC algorithms and how those algorithms deploy the principles of quantum physics to solve the problem. This book connects the physics concepts, the computer science vocabulary, and the mathematics, providing a complete picture of how QIS and QC work. The authors give multiple representations of the concept—textual, graphical, and symbolic (state vectors, matrices, and Dirac notation)—which are the lingua franca of QIS and QC. Those multiple representations allow the readers to develop a broader and deeper understanding of the fundamental concepts and their applications. In addition, the book provides examples of recent experimental demonstrations of quantum teleportation and the applications of quantum computational chemistry. The last chapter connects to the growing commercial world of QC and QIS and provides recommendations for further study.

Abstract In this work, we study the Wigner phase-space representation of qubit states encoded in continuous variables (CV) by using the Gottesman–Kitaev–Preskill (GKP) mapping. We explore a possible connection between resources for universal quantum computation in discrete-variable (DV) systems, i.e. non-stabilizer states, and negativity of the Wigner function in CV architectures, which is a necessary requirement for quantum advantage. In particular, we show that the lowest Wigner logarithmic negativity corresponds to encoded stabilizer states, while the maximum negativity is associated with the most non-stabilizer states, H-type and T-type quantum states.

Full text
Abstract:
This paper describes the work carried out by the Inter-American Development Bank, the IDB Lab, LACChain, Cambridge Quantum Computing (CQC), and Tecnológico de Monterrey to identify and eliminate quantum threats in blockchain networks. The advent of quantum computing threatens internet protocols and blockchain networks because they utilize non-quantum resistant cryptographic algorithms. When quantum computers become robust enough to run Shor's algorithm on a large scale, the most used asymmetric algorithms, utilized for digital signatures and message encryption, such as RSA, (EC)DSA, and (EC)DH, will be no longer secure. Quantum computers will be able to break them within a short period of time. Similarly, Grover's algorithm concedes a quadratic advantage for mining blocks in certain consensus protocols such as proof of work. Today, there are hundreds of billions of dollars denominated in cryptocurrencies that rely on blockchain ledgers as well as the thousands of blockchain-based applications storing value in blockchain networks. Cryptocurrencies and blockchain-based applications require solutions that guarantee quantum resistance in order to preserve the integrity of data and assets in their public and immutable ledgers. We have designed and developed a layer-two solution to secure the exchange of information between blockchain nodes over the internet and introduced a second signature in transactions using post-quantum keys. Our versatile solution can be applied to any blockchain network. In our implementation, quantum entropy was provided via the IronBridge Platform from CQC and we used LACChain Besu as the blockchain network.

Abstract:
The article discusses the possibility of using the technological advantages that appear in connection with the discovery of the physical essence of Time and new interpretation of the structure of space in the form of space-time quanta. One of the problems that can be successfully solved on the basis of the new physical model is the problem of establishing the true nature of gravity. The solution to this problem is directly related to the implementation of the idea of unsupported motion based on the interaction in a certain way of the created asymmetric interference structure of longitudinal waves with the natural structure of spatial frequencies.

Abstract:
This qualification study is based on the need for a new technology in the asset integrity lifecycle of pipelines including Subsea infrastructure. As of today it is challenging to identify a technology that combines adequate measurement accuracy combined with the ability to operate in gaseous atmosphere found inside natural gas pipelines. Halfwave�s inspection method developed over the last two decades is based on Acoustic Reso-nance Technology (ART), which utilizes the natural frequencies of the pipe wall to determine the remaining wall thickness. The most prominent advantages of ART comprise (i) direct measure-ments of wall thickness with a accuracy within 0.2 mm (95% c.l.), (ii) the broad-band frequency range enables measurements in pressurized gas, avoiding a liquid couplant, and (iii) the transducer matrix with (a flexible) stand-off to the wall enables high-resolution internal geometry mapping of the pipeline to a resolution within 50 �m (95% c.l.). Additional benefits include the ability to detect disbondmant of external coating and delamination in the pipe wall material. ART is a well-known inspection technology dating back to the 1940s in e.g. the aviation industry, scanning air craft wings, and has also been extensively used in connection with integrity measure-ment of down-hole casings (cf. e.g. the USIT tool, by Schlumberger). However, the last decade�s development of broad-band transducers combined with a surge in storage technology has moved the operational envelope and accuracy of ART a quantum leap ahead, offering much more relia-bility in the integrity evaluations of natural gas pipelines. In turn this gives significantly enhanced decision confidence for the pipeline operator. This document will provide a description of ART and also Halfwave�s application of ART within the Oil and Gas industry.
