Course description
The course will be based on graduate course of quantum mechanics. It will start with advanced quantum mechanics of open systems: master equation and Lindblad operators. Measurements theory [including POVM]; trace preserving completely positive maps [of density matrices]; as well as Bell inequalities will be explained.
Entanglement theory will start with measures of entanglement: von Neumann entropy, Renyi entropy and negativity.
Application of entanglement for analysis of dynamical systems will be explained, including entanglement Hamiltonian. Holographic approach for description of entanglement entropy also will be explained.
Information theory [starting from Shannon theorems about channel capacity] will be related to statistical physics and probability theory.
Algorithm theory: Shor's and Grover's quantum algorithms. Quantum cryptography also will be explained [BB84].
Different approaches to building of quantum computers: solid state [fractional quantum Hall effect and Josephson junction] and quantum optics [including optical lattices, cold atoms, ion traps and electromagnetically induced transparency]. Different architectures of quantum computation: circuit, adiabatic, topological quantum computation [including models of anyons] and measurement based quantum computation.
Application of ideas of quantum information to condensed matter also will be explained: topological phases of matter [including conformal field theory], Kitaev model, spin chains (VBS, Takhtajan-Babujan model), topological Kondo model and Sachdev-Ye-Kitaev model. Also generalized Gibbs ensemble will be explained. Simulation of models of mathematical physics in optical lattices [massive Thirring model, XXZ spin chain and Lieb-Linger model].
Computational physics also will be mentioned: MERA (and its relation to AdS) matrix product states and relation to algebraic Bethe ansatz.
New exactly solvable spin chains, emerging from quantum information [Shor-Movassagh, Fredkin] will be mentioned. Advances material form the program
Entanglement and Dynamical Systems
will be mentioned. Guest lecturers [theorists, mathematicians and experimentalists] will be invited.
