  "abstract": "Quantum many-body scars are a core mechanism of weak ergodicity breaking, but deterministically protecting and scaling these fragile coherent states remains a great challenge. We propose a purely geometric scheme based on connectivity engineering: by reconstructing the network topology with fixed-step hopping, the parent system is strictly decoupled into multiple equal-length independent sub-chains. We validate this mechanism in the PXP model featuring scar states. Numerical results demonstrate that within the decoupled network, the sub-chain interiors not only independently inherit the many-body scar properties of the parent (manifested as long-lived staggered magnetization oscillations and finite-size revivals of entanglement entropy), but also, due to the geometric blockades, the cross-channel quantum mutual information is strictly blocked at the machine precision limit. This mechanism requires no complex external fine-tuning, providing a minimal and deterministic blueprint for multi-channel quantum memory multiplexing in quantum chips.",
