题目：Phase space representation of subdynamics of the two-mode squeezed state (1)-(6)
摘要: The lecture starts with summary of basic issues about pure states, mixed states, density matrices, the concept of partial trace, decoherence, entanglement (in pure states) etc.. Then, the Kraus representation of subdynamics and positive operator-valued measures (POVMs) are explained. It is shown that the phase space representation helps intuitive understanding of these abstract quantum operations. To illustrate this point, subdynamics of the two-mode squeezed state is discussed as an example, in detail and is proven to be invertible (reversible). Finally, this invertibility is examined in view of behaviors of the von Neumann entropy under unitary, unital and non-unital operations.
