Differential geometry of quantum channel estimation

Fujiwara, A (Osaka)
Thursday 18 November 2004, 10:30-11.15

Seminar Room 1, Newton Institute

In this talk, I will review some recent developments in quantum channel estimation theory, putting emphasis on an active interplay between noncommutative statistics and information geometry.
