Information Causality and Noisy Computations

Understand

We reformulate the information causality in a more general framework by adopting the results of signal propagation and computation in a noisy circuit.

• In our framework, the information causality leads to a broad class of Tsirelson inequalities.
• This fact allows us to subject information causality to experimental scrutiny.
• A no-go theorem for reliable nonlocal computation is also derived.
