Extremal points of the quantum set in the CHSH scenario: conjectured analytical solution

Understand

Quantum mechanics may revolutionise many aspects of modern information processing as it promises significant advantages in several fields such as cryptography, computing and metrology.

• Quantum cryptography for instance allows us to implement protocols which are device-independent, i.e.
• they can be proven security under fewer assumptions.
• These protocols rely on using devices producing non-local statistics and ideally these statistics would correspond to extremal points of the quantum set in the probability space.
