Quantum Cryptography: Exploring Quantum Algorithms and Mixed States

Welcome to 'Quantum Algorithms & Cryptography' course ! This lecture continues the discussion on mixed states and density matrices. It proves the properties of density matrices, including the fact that their trace is 1 and they are positive semi-definite and Hermitian. The lecture also explains how to represent a mixed state in terms of its eigenvalues and eigenvectors and elaborates on the concept of a maximally mixed state.
