From Quantum Beats to Topological Protection: A Stratum-Based Hybrid Architecture Integrating NV Centers, Weyl Interfaces, and Majorana Qubits for Fault-Tolerant Quantum Computing Mehmet Keçeci Orcid: https://orcid.org/0000-0001-9937-9839 Abstract: The realization of scalable and fault-tolerant quantum computing systems requires not only the development of qubits with long coherence times but also the integration of heterogeneous physical platforms within a unified architectural framework. This study proposes a Stratum-based hybrid quantum computing architecture that combines the precise quantum state control enabled by nitrogen-vacancy (NV) centers in diamond, the topological interface properties of Weyl semimetals, and the intrinsic error resilience provided by Majorana zero modes. The primary objective of this work is to establish a theoretical foundation for next-generation fault-tolerant quantum systems by integrating high-fidelity spin manipulation mechanisms derived from quantum beat phenomena with topologically protected information-processing layers. Within the proposed framework, the Stratum Model conceptualizes each physical, functional, and topological component of the quantum architecture as an independent yet dynamically interacting layer. NV centers constitute the control and sensing strata responsible for quantum state preparation, precision measurements, quantum memory operations, and quantum network node functionalities. Quantum beats serve as a dynamic characterization mechanism for spin superposition states within these layers, enabling high-accuracy monitoring and manipulation of coherent quantum dynamics. In contrast, Weyl interfaces are modeled as intermediary topological strata that govern transitions between distinct topological phases while facilitating robust and protected transfer of quantum information carriers across heterogeneous subsystems. At the highest operational level, Majorana qubits form the topological computing layer of the architecture. Through nonlocal quantum information encoding, they provide inherent robustness against environmental noise, decoherence, and local perturbations. Interactions among architectural layers are defined not only by physical interconnections but also through topological invariants, connectivity structures, error-propagation pathways, and quantum information flow dynamics. In this context, the Stratum approach extends beyond conventional spatial-layer descriptions by incorporating layer diversity, topological protection mechanisms, qubit heterogeneity, and fabrication imperfections into a common analytical framework. Furthermore, the model introduces novel design strategies for isolating defective or degraded strata, preserving critical topological regions, and mitigating system-level error propagation. The findings suggest that the integration of the precise quantum control capabilities of NV centers with the intrinsic topological protection offered by Majorana-based platforms may generate a powerful synergistic effect capable of enhancing quantum computational performance. Weyl interfaces are proposed to act as both physical and topological bridges between these two paradigms, enabling coherent communication across distinct quantum subsystems. Consequently, the proposed Stratum-based hybrid architecture provides an integrated design paradigm applicable to a broad spectrum of emerging quantum technologies, ranging from quantum sensing and distributed quantum networks to topological quantum processors and large-scale fault-tolerant quantum computers.
