## A Short Course in Quantum Information Theory: An Approach from Theoretical PhysicsThis concise primer combines the twin vantage points of theoretical physics and the unity of physics. It strips quantum information science to its basics by linking it to universal concepts in physics. Designed as an extensive lecture rather than a textbook, the book is based on courses delivered over several years to advanced undergraduate and beginning graduate students, and addresses anyone with a working knowledge of basic quantum physics. |
