Recently we developed a framework for building large self-tests by repeating a smaller self-test many times in parallel. However, the framework did not apply to the CHSH test, which tests a maximally entangled pair of qubits.
WebIn the case of polarisation entangled photon pairs (as emitted from the quED ), the so-called “CHSH” inequality is often chosen. Classical (“local realistic”) theories predict that a certain value “S” has an upper bound of 2 …
