Quantum Information Theory (RWTH Aachen University)

A lecture by Maarten Wegewijs - States (mixtures, marginals, ensembles, bipartite states, purification) - Measurements (effects operators, POVM, measurement operators, state discrimination, state identification, instruments, information-disturbance, remote steering) - Evolutions (complete positivity, channels, state-evolution correspondence, unitary dilation, complementary channel, entropy exchange, decoupling principle, error-correction conditions, recovery channel) - Entanglement (entropy, LOCC, majorization, single-copy conversion, typicality, asymptotic conversion) For questions contact anki (at) senseb.at
