Classical and quantum bounds on multi-system equality

Ernesto F. Galvão – UFF

Abstract:

I will describe how we can use logic to impose constraints on the probability of the conjunction (AND) of n propositions. This is an example of logical coherence inequalities that were first investigated by George Boole (1854). By taking each proposition to be about the equality of two systems, we obtain a logical coherence condition for the joint equality of multiple systems. I will then show that quantum mechanics violates this condition, and obtain bounds for the quantum violation. This enables us to bound the value of unmeasured two-state overlaps, with applications in quantum optics and quantum information.
This is joint work with Daniel Brod.
