Data Fest Online 2020 Math Optimization Track https://ods.ai/tracks/optimization-df2020 In the second video, we discuss quantum observables. Essentially quantum observables are physical observables that can be measured in an experiment. Due to the features of quantum mechanics, quantum observables are different in comparison with classical ones. We discuss this difference in the video and pay attention to analogies between quantum and classical cases.
