GHZ paradoxes based on an even number of qubits
Mordecai Waegell, P. K. Aravind
GHZ paradoxes are presented for all even numbers of qubits from four up. They are obtained from proofs of the Kochen-Specker (KS) theorem by showing how the assumption of noncontex…

Proofs of the Kochen-Specker theorem based on a system of three qubits
Mordecai Waegell, P. K. Aravind
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…
