Proofs of the Kochen–Specker theorem based on a system of three qubits

Proofs of the Kochen–Specker theorem based on a system of three qubits

A number of new proofs of the Kochen-Specker theorem are given based on the observables of the three-qubit Pauli group. Each proof is presented in the form of a diagram from which it is obvious by inspection. Each of our observable-based proofs leads to a system of projectors and bases …
