Specular Multi-Qubit Engines extend the Specular Framework to quantum systems composed of multiple interacting qubits. These engines operate on the dual-sheet manifold Mₛpec = M x H, where quantum evolution, geometric curvature, informational flow, and phase-driven collapse dynamics coexist within a unified informational structure. Multi-qubit interactions, coherence, decoherence, and collapse arise from the informational-specular weight tensor WAB, the informational boson Bₛpec (theta), and the stability operator Lₛpec. Informational gradients and phase activation govern cross-sheet coupling, determine interaction strength, and control transitions between quantum-stable, geometric-stable, and transitional regimes. The architecture integrates quantum, geometric, informational, and phase components into a single operational framework. Applications include informational quantum computing architectures, collapse-based control mechanisms, informational error correction, multi-observer qubit networks, and numerical simulations of dual-sheet dynamics. This work establishes the foundations of multi-qubit informational physics and provides a structural basis for future quantum technologies built on the Specular Framework.
