Construction of Three-Qubit Kochen-Specker Sets
SP Toh
Contextuality is one of the fundamental deviations of quantum mechanics from classical physics. The Kochen-Specker (KS) theorem shows that non-contextual classical physics with hid…

Kochen-Specker Sets with Thirty Rank-Two Projectors in Three-Qubit System
S. P. Toh
A simple three rules supplemented by five steps scheme is proposed to produce Kochen-Specker (KS) sets with 30 rank-2 projectors that occur twice each. The KS sets provide state-in…

Generating the Kochen-Specker Sets with 36, 38 and 40 Rays in Three-qubit System: Three Simple Algorithms
S. P. Toh
We put forward three simple algorithms to generate Kochen-Specker sets used for parity proof of Kochen-Specker theorem in three-qubit system. These algorithms enables us to generat…
