A method strengthens Mermin-Klyshko-Bell inequalities beyond local bounds for entanglement detection in multipartite systems using coarsely calibrated measurements and derives trade-offs for separable versus general states.
As the upper boundβt(ab|c) is independent of the underlying state, it holds true also for a generalAB|C state
