Course description and aims

Quantum field theory and quantum information
Lecturer: Tatsuma Nishioka

In these lectures I will discuss the constraints quantum information theory imposes on the dynamics of quantum field theory. The basics of quantum information will be reviewed with the emphasis on quantum information measures. The definition and computational methods of the measures will be developed in the framework of quantum field theory. To exemplify the power of quantum informational approach to quantum field theory, I will derive some constraints on renormalization group flow and energy conditions.
