Introduction to quantum computing III

Fang Song
Portland State University

This lecture will introduce an alternative formalism of quantum information based on density matrices. We will study mixed states, purification, quantum channels, POVM measurement, distance measures of quantum states and operators, which will be useful in modeling and analyzing security of both post-quantum and quantum cryptography.
