5. 18. Quantum State Analysis : Probability theory as logic in Quantum mechanics

   Author : Anders Månsson; Anders Karlsson; Gunnar Björk; Ingemar Bengtsson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; quantum; quantum mechanics; state; state analysis; probability; probability theory; logic; Photonics; Fotonik;

   Abstract : Quantum mechanics is basically a mathematical recipe on how to construct physical models. Historically its origin and main domain of application has been in the microscopic regime, although it strictly seen constitutes a general mathematical framework not limited to this regime.
