Kochen-Specker Theorem for a Single Qubit
Toh, Sing Poh and Zainuddin, Hishamuddin (2008) Kochen-Specker Theorem for a Single Qubit. Math Digest : Research Bulletin Institute for Mathematical Research, 2 (1). pp. 11-14. ISSN 1985-2436
The Kochen-Specker theorem (KS) states that Ilonconrextual hidden variable theories are incompatible with quantum mechanics. Since the first proof of the theorem, von Neumann projection measurement has been used and the quantum system considered has dimensionality of at least three. However, recently generalized measurements represented by positive-operator-va!ued measures (POVM) have been applied to extend the proof to two dimensional quantum systems. This note gives numerical calculations on the first KS proof for a single qubit.
