A Short Course in Quantum Information Theory [electronic resource] : An Approach From Theoretical Physics / by Lajos Diósi.

Foundations of classical physics -- Semiclassical—semi-Q-physics -- Foundations of q-physics -- Two-state q-system: qubit representations -- One-qubit manipulations -- Composite q-system, pure state -- All q-operations -- Classical information theory -- Q-information theory -- Q-computation.

This short and concise primer takes the vantage point of theoretical physics and the unity of physics. It sets out to strip the burgeoning field of quantum information science to its basics by linking it to universal concepts in physics. An extensive lecture rather than a comprehensive textbook, this volume is based on courses delivered over several years to advanced undergraduate and beginning graduate students, but essentially it addresses anyone with a working knowledge of basic quantum physics. Readers will find these lectures a most adequate entry point for theoretical studies in this field.
