Cardinality-Resolved Interference Accessibility in Multipartite Quantum Systems: A trace-norm framework for measurement-assisted coherence and its use in quantum hardware diagnostics

A single-qubit Ramsey or T2 measurement reports how much interference survives on a qubit, but not why the rest is missing. Phase information lost to an unobserved environment and phase information coherently redistributed into neighbouring qubits produce the same local signature...
