Here, we present a theoretical framework for a fault-tolerant quantum computing platform operating at room temperature, based on the topological protection of orbital angular momentum (OAM) monopoles in chiral semimetals. We propose a qubit architecture where logical states are encoded in superpositions of chiral currents, whose stability is enforced by the chiral anomaly. First-principles calculations and quantum dynamics simulations predict coherence times (T₂) exceeding 500 ms at 300 K, a value orders of magnitude greater than current cryogenic systems. Coupling these solid-state qubits to photonic OAM modes is predicted to extend T₂ into the 10–100 s range. This framework, which leverages intrinsic topological and chiral properties of matter to suppress decoherence, provides a viable route towards scalable, energy-efficient quantum technologies.
