Topological Quantum Computing: Principles, Advances, and Implications in Acta Universi

Topological quantum computing (TQC) represents a paradigm shift in quantum information processing, leveraging the topological properties of quantum states to create inherently fault-tolerant qubits. Unlike conventional qubits (superconducting or trapped ions), topological qubits are protected by the global geometry of their wavefunctions, making them robust against local noise and decoherence. This approach, rooted in the work of Alexei Kitaev (1997), promises to solve the scalability crisis of quantum computers. As of December 10, 2025, TQC is transitioning from theory to prototypes, with breakthroughs from Microsoft, Cornell–IBM, and others marking a pivotal year
