This work presents a comprehensive theoretical and computational study of quantum entropy and information processing during black hole mergers, using a working entropic correction scale β = 0. 1 and a calibrated multi-channel numerical estimate βₜheoretical ≈ 0. 0952 within an explicit phenomenological framework. The approach combines quantum information theory, entanglement-entropy estimates, and holographic ideas to relate entropy change during mergers to the efficiency of quantum information processing. Using quantum-circuit merger models, we show that at fixed β = 0. 1 the efficiency diagnostic is exactly 1. 00 for all analyzed events (i. e. , consistency of the definition with the numerical pipeline). The predictions are tested on thirteen LIGO/Virgo gravitational-wave events, yielding 100% agreement for information-processing efficiency and 84. 6% agreement for entropic corrections. Key results include: (1) a calibrated multi-channel estimate βₜheoretical ≈ 0. 0952 ≈ 0. 1; (2) full agreement of the efficiency diagnostic with 1/β = 10 at β = 0. 1; (3) a phenomenological link between entropy evolution and the black-hole information paradox via Page-curve considerations; and (4) broad experimental cross-checks on LIGO/Virgo data. Overall, the work establishes a phenomenological link between quantum information theory and gravitational physics, and provides a reproducible perspective on the quantum-information interpretation of black-hole merger entropy.
