We propose a quantum multiverse model where universes are characterized by discrete energy levels ("tiers"), distinguished by quantum energy gaps and Hubble-scaled screening effects while sharing identical physical laws. Transitions between tiers, mediated by screened Yukawa interactions, drive cosmic evolution and generate distinct observational signatures. The model predicts a scale-invariant primordial power spectrum (nₛ0. 96) from inflationary transitions, high-frequency gravitational waves (₆ₖ10^-15 at 1 kHz) during reheating, and late-time phantom dark energy (w-1. 03) all consistent with Planck and DESI 2024 data. Crucially, the framework resolves baryogenesis through multiverse-mediated antimatter ejection, yielding the observed matter-antimatter asymmetry (610^-10), and unifies inflation, reheating, and dark energy through quantum transitions that preserve unitarity and the energy-time uncertainty principle. With testable predictions for CMB-S4, Einstein Telescope, and next-generation surveys, this work provides a compelling, falsifiable alternative to ΛCDM that bridges quantum mechanics and cosmology without fine-tuning.
