23 The course addresses **physicists and mathematicians** at advanced undergraduate or graduate level. For physics students the course will provide an introduction to theory and examples of quantum systems interacting with their environment. For students of mathematics the course will provide an introduction into to an algebraic treatment of probability and Markov processes.
24
25 == Content ==
26
27 * probabilistic foundations of quantum mechanics
28 * composite systems, entanglement
29 * quantum channels alias completely positive maps
30 * quantum Markov processes
31 * Lindblad equation
32 * repeated interaction systems
33 * stochastic Schrödinger equation
34
35 == Requirements ==
36
37 The course requires linear algebra and differential calculus as discussed in the basic courses. In addition, some very basic understanding of probability is needed. For physicists we recommend some pre-knowledge in quantum mechanics.
38
39 == Literature ==
40
41 The main part of the course will rely on the following books:

43 1. Breuer, H.-P., Petruccione, F.: //The Theory of Open Quantum Systems//, Oxford University Press, 2002
44 1. Wiseman, H. M., Milburn, G. J.: //Quantum Measurement and Control//, Cambridge University Press, 2009\\
