Лекция Проф. Бужека на физфаке МГУ
23 января 2014 года, в четверг, в 15:00, в конференц-зале библиотеки физфака МГУ (5 этаж) состоится лекция Проф. Владимира Бужека (Research Ctr for Quantum Information, Bratislava) на тему "Квантовые наблюдения". Приглашаются все желающие.In my talk I will outline some epistemological as well as operational problems associated with the quantum theory of measurement. I will address several topics including:
Basic concepts – Why quantum measurements are so much different from classical observations? Maximum entropy principle - I will discuss how states of quantum systems can be reconstructed from incomplete experimental data when meanvalues of a limited number of the system observables are available from a measurement.
Quantum “clickology” - I will show how information can be extracted from finite-size ensembles of identically prepared quantum systems. I will discuss the role of resources available in measurement. In particular, I will present quantum version of the Bayesian inference method.
Recycling of quantum information - I will address a question whether one can extract some useful information from a quantum system that has already been measured. Reconstruction of quantum channels - I will also show how quantum channels can be reconstructed from incomplete experimental data.
Compression of quantum information - I will analyse how classical information can be efficiently compressed and encoded into quantum systems.
