Query: Theory-Independent Measure of Coherence   We provide a theory independent framework to quantify coherence. In
comparison with Bell's theory independent approach to quantum nonlocality, we
characterize a general coherence phenomenon with statistics arising from
sequential measurements of observables that might not be compatible. By
introducing a "decohered" state after the sharp measurement of some preferred
observable, we quantify coherence by either the difference of initial
"superposed" state from the "decohered" state or the measurement outcome
deviations when they subjected to further measurements. Applied to quantum
mechanics, the outcome-difference measures yield two novel quantum coherence
measures, one of which upper-bounds quantum interference visibility. In the
Bell's scenario, we find a finite gap of coherences between a super non-local
model and quantum mechanic and therefore our framework can help to single out
quantum mechanics beyond non-locality.
