Measurement theory in local quantum physics
Kazuya Okamura, Masanao Ozawa (Nagoya Univ.)
Abstract (in Japanese) (See Japanese page) 
(in English) We aim at establishing measurement theory in local quantum physics.For this purpose, we discuss a representation theory of completely positive (CP) instruments.We introduce a condition called the normal extension property (NEP)
and establish a one-to-one correspondence between CP instruments with NEP and statistical equivalence classes of measuring processes. Moreover, two examples of CP instruments without NEP are given. Local measurements in algebraic quantum field theory are also developed.
