Quantum Body: The New Science of Living a Longer, Healthier, More Vital Life

by Deepak Chopra Jack Tuszynsk Brian Fertig

Joining forces with two leading scientists, New York Times bestselling author Deepak Chopra offers a quantum leap for improving our physical and mental health. In an unprecedented collaboration between three of today&’s most powerful minds, Deepak Chopra, M.D., teams up with physicist Jack Tuszynski, Ph.D., and endocrinologist Brian Fertig, M.D., to bring readers a visionary work that delves into the innovative world of quantum science and shows how unlocking its secrets can revolutionize how we live and age—and, ultimately, how we can eradicate disease. The key is the quantum body. Unlike our physical body, which is subject to aging, injury, and decay, the quantum body exists on a sub-atomic level and is the infinite, invisible source of everyday reality that affects your thoughts, feelings, sensations, and biological responses. Without your quantum body, there is no physical body. And this lack of awareness of the most crucial part of ourselves negatively impacts our lives every day. Through a powerful combination of prescriptive exercises and innovative research into the quantum world, the authors unveil seven breakthroughs that will revolutionize the future of everyone&’s well-being. Central to this revolution is a groundbreaking understanding of metabolism—the way our cells process energy—that promises to challenge our understanding of modern medicine as we know it.Though all too familiar in the physical world, Alzheimer&’s, type 2 diabetes, cancer, and heart disease do not exist at the fundamental level of quantum reality. By harnessing the power of the quantum body, we can significantly improve our physical and mental well-being, including supporting healthy cell, tissue, and organ function, boosting immunity, promoting mental resilience, and expanding our understanding of what it means to live a happy and purposeful life.In this groundbreaking book, Chopra, Tuszynski, and Fertig show you the way by unveiling the &“real&” reality of your body and mind as never before and providing a vision for a tomorrow that is already here.

Quantum Bullsh*t: How to Ruin Your Life with Advice from Quantum Physics

by Chris Ferrie

Science is so f*cking rad. We don't deserve it.What actually is quantum physics? If you can answer that questions without bullsh*tting the person standing next to you in the bookstore, you can stop reading right now. But although most of us don't actually understand quantum physics, we know that it's mystical and awesome, and if we understood it we'd probably be rich and beautiful and happy, right? After all, there are plenty of people out there trying to sell you quantum crystals to align your quantum energy with your quantum destiny. Can they all be wrong?Spoiler: yes. Yes, they can. There is no such thing as quantum crystals. Sorry!Luckily, as pseudo-science takes over the internet and it's getting harder and harder to separate alternative facts from real science, Chris Ferrie (an actual quantum physicist!) is here to explain quantum physics in a way that makes sense, so you can see the hucksters and bullsh*tters coming from a mile away—and school them in what quantum entanglement actually is (it has nothing to do with your romantic life). If you f*cking love science and want to be slightly less dumb than you were when you woke up this morning, Quantum Bullsh*t is the truly out-of-this-world book for you.

Quantum Chance

by Nicolas Gisin

Quantum physics, which offers an explanation of the world on the smallest scale, has fundamental implications that pose a serious challenge to ordinary logic. Particularly counterintuitive is the notion of entanglement, which has been explored for the past 30 years and posits an ubiquitous randomness capable of manifesting itself simultaneously in more than one place. This amazing 'non-locality' is more than just an abstract curiosity or paradox: it has entirely down-to-earth applications in cryptography, serving for example to protect financial information; it also has enabled the demonstration of 'quantum teleportation', whose infinite possibilities even science-fiction writers can scarcely imagine. This delightful and concise exposition does not avoid the deep logical difficulties of quantum physics, but gives the reader the insights needed to appreciate them. From 'Bell's Theorem' to experiments in quantum entanglement, the reader will gain a solid understanding of one of the most fascinating areas of contemporary physics.

Quantum Chromodynamics Sum Rules (SpringerBriefs in Physics)

by Cesareo A. Dominguez

This concise book provides the necessary background to allow interested readers to launch original research projects on the subject matter. Currently, this material is not available from one single source, and is either spread out over numerous journal publications, or covered in long and technical monographs. At the core of this book lies the sum rule approach to obtain analytic results in Quantum Chromodynamics (QCD), the current theory of strong interactions among quarks and gluons. This method fully complements Lattice QCD, the corresponding computational approach based on discretizing QCD on a space-time lattice. Applications include standard determinations of hadronic particle properties with extensions to finite temperature and density, and possibly involving the presence of extreme magnetic fields. The latter cases include stellar objects (e.g. neutron stars and magnetars) as well as high-energy proton–proton and heavy-ion collisions. Further topics concern the determination of the fundamental parameters of QCD, e.g. quark masses and the quark–gluon couplings, the hadronic contribution to the anomalous magnetic moment of the muon, and electromagnetic coupling at the the W-boson mass scale.

Quantum Codes for Topological Quantum Computation (SpringerBriefs in Mathematics)

by Clarice Dias Albuquerque Eduardo Brandani Silva Waldir Silva Soares Jr.

This book offers a structured algebraic and geometric approach to the classification and construction of quantum codes for topological quantum computation. It combines key concepts in linear algebra, algebraic topology, hyperbolic geometry, group theory, quantum mechanics, and classical and quantum coding theory to help readers understand and develop quantum codes for topological quantum computation.One possible approach to building a quantum computer is based on surface codes, operated as stabilizer codes. The surface codes evolved from Kitaev's toric codes, as a means to developing models for topological order by using qubits distributed on the surface of a toroid. A significant advantage of surface codes is their relative tolerance to local errors. A second approach is based on color codes, which are topological stabilizer codes defined on a tessellation with geometrically local stabilizer generators. This book provides basic geometric concepts, like surface geometry, hyperbolic geometry and tessellation, as well as basic algebraic concepts, like stabilizer formalism, for the construction of the most promising classes of quantum error-correcting codes such as surfaces codes and color codes.The book is intended for senior undergraduate and graduate students in Electrical Engineering and Mathematics with an understanding of the basic concepts of linear algebra and quantum mechanics.

Quantum Collision Theory of Nonrelativistic Particles: An Introduction

by Reiner M. Dreizler Tom Kirchner Cora S. Lüdde

This book introduces the scattering theory of nonrelativistic systems, a standard tool for interpreting collision experiments with quantum particles at energies not too high. The goal is to explore the interaction between particles and their properties. The authors cover the basics of the theory through a detailed discussion of elastic scattering using the stationary Schrödinger equation and the Lippmann-Schwinger equation. These remarks are supplemented by a consideration of the time-dependent formulation of scattering theory. Selection rules for effective cross sections due to symmetries conditioned by the structure of the interparticle forces and the scattering of spin-polarized particles are discussed. The foundations for the treatment of inelastic processes are laid and explained by application to three-body and nucleotransfer processes.In all chapters, the more technical, mathematical aspect and the more physics-oriented explanations are separated as far as possible. The explanations are well comprehensible and suitable to introduce the reader to the physics of impact processes.This book is a translation of the original German 1st edition Streutheorie in der nichtrelativistischen Quantenmechanik by Reiner M. Dreizler, Tom Kirchner & Cora S. Lüdde, published by Springer-Verlag GmbH Germany, part of Springer Nature in 2018. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). The present version has been revised extensively with respect to technical and linguistic aspects by the authors. Springer Nature works continuously to further the development of tools for the production of books and on the related technologies to support the authors.

The book brings together quantum networking, quantum information theory, quantum computing, and quantum simulation.

Quantum Computation and Logic: How Quantum Computers Have Inspired Logical Investigations (Trends in Logic #48)

by Maria Luisa Dalla Chiara Roberto Giuntini Roberto Leporini Giuseppe Sergioli

This book provides a general survey of the main concepts, questions and results that have been developed in the recent interactions between quantum information, quantum computation and logic. Divided into 10 chapters, the books starts with an introduction of the main concepts of the quantum-theoretic formalism used in quantum information. It then gives a synthetic presentation of the main “mathematical characters” of the quantum computational game: qubits, quregisters, mixtures of quregisters, quantum logical gates. Next, the book investigates the puzzling entanglement-phenomena and logically analyses the Einstein–Podolsky–Rosen paradox and introduces the reader to quantum computational logics, and new forms of quantum logic. The middle chapters investigate the possibility of a quantum computational semantics for a language that can express sentences like “Alice knows that everybody knows that she is pretty”, explore the mathematical concept of quantum Turing machine, and illustrate some characteristic examples that arise in the framework of musical languages. The book concludes with an analysis of recent discussions, and contains a Mathematical Appendix which is a survey of the definitions of all main mathematical concepts used in the book.
