To evaluate whether redundant environmental encoding in Quantum Darwinism is sufficient to account for emergent classical objectivity within the Many-Worlds Interpretation.
Simulated redundant environmental encoding of pointer states using a qubit test model implemented in Qiskit.
Analyzed theoretical connections between Quantum Darwinism, Strong Quantum Darwinism, Spectrum Broadcast Structure, and Quantum Discord regarding phase recoverability.
Redundant encoding of pointer states across environmental fragments is shown to be necessary but insufficient for fully explaining classical objectivity.
Phase anti-redundancy is introduced as an essential condition, wherein cross-branch phase information remains globally correlated and practically unrecoverable by local environmental fragments.

Implication

Theoretical modeling shows environmental redundancy is insufficient for branch objectivity in many-worlds quantum mechanics, suggesting classical records require global phase anti-redundancy.
