Measuring processes and the Heisenberg picture
Kazuya Okamura
In this paper, we attempt to establish quantum measurement theory in the Heisenberg picture. First, we review foundations of quantum measurement theory, that is usually based on th…

Measurement theory in local quantum physics
Kazuya Okamura, Masanao Ozawa
In this paper, we aim to establish foundations of measurement theory in local quantum physics. For this purpose, we discuss a representation theory of completely positive (CP) inst…

Local state and sector theory in local quantum physics
Izumi Ojima, Kazuya Okamura, Hayato Saigo
We define a new concept of local states in the framework of algebraic quantum field theory (AQFT). Local states are a natural generalization of states and give a clear vision of lo…
