日期：107年11月23日

時間：15:10 - 17:00

地點：理工一館 A324 (大會議室)

演講題目：量子訊息論與保持問題 Quantum information theory and preserver problems

演講摘要：

I will present some of my works on the quantum information theory. Here, quantum data refers

to positive density matrices/operators and quantum channels refer to completely positive maps .

The story starts with the Wigner theorem on transition probability. My study on several preserver

problems of function, matrix and operator algebras follow. A typical problem states that whether

two quantum systems modeled von Neumann algebras are isomorphic if they share identical

transition probability structures. The talk will end by a briefing of my recent works on divergence

preserver problem, which are applications of Bregman distances developed in the optimization theory.
