“Meet Henry Bar, a physicist and … quantum superhero.” The title The Quantum Matrix refers to a central concept in quantum physics, but also (allegorically) to our enigmatic world. In this book, Henry Bar, physicist and the first quantum superhero, guides the reader through the amazing quantum world. Henry’s hair-raising adventures in his perilous struggle for quantum coherence are graphically depicted by comics and thoroughly explained to the lay reader. Behind each adventure lies a key concept in quantum physics. These concepts range from the basic quantum coherence and entanglement through tunneling and the recently discovered quantum decoherence control, to the principles of the emerging technologies of quantum communication and computing. The explanations of the concepts are popular, but nonetheless rigorous and detailed, and are followed by their broader context, their historic perspective, up-to-date status and forthcoming developments. Finally, thought-provoking philosophical and cultural implications of these concepts are discussed. The mathematical appendices of all chapters cover, in a straightforward manner, the core aspects of quantum physics at the level of a university introductory course. The Quantum Matrix presents an entertaining, popular yet comprehensive picture of quantum physics. It can be read as a light-hearted illustrated tale, a philosophical treatise or a textbook. Either way, the book lets the reader delve deeply into the wondrous quantum world from diverse perspectives and obtain glimpses into the quantum technologies that are about to reshape our lives. May the reader’s voyage through the quantum world charted by this book be both pleasant and rewarding.
