Summary

Identical finite-copy states received different contributor rankings under different physical readout models.

The authors incorporate physical access into Shapley data valuation because unknown quantum states are consumable rather than reusable records. They prove exact links between richer access and the largest possible ranking reversal, then show numerically that the same samples can change value solely because the permitted measurements changed.

Why it matters

Identical finite-copy states received different contributor rankings under different physical readout models.
