Visionary Framework for Room-Temperature Quantum Computing with Chiral OAM Qubits

Quantum coherence, critical for superposition and entanglement, underpins quantum computing’s transformative potential. This visionary case study proposes a novel platform using chiral qubits based on orbital angular momentum (OAM) in topological semimetals (e.g., CoSi, TaAs). Leveraging OAM monopoles—chirality-locked, isotropic orbital textures observed via circular dichroism in angle-resolved photoemission spectroscopy (CD-ARPES)—simulations predict coherence times of 0.5–5 ms at 8 K and 50–500 ms at 300 K, potentially extending to 10–100 s through photonic OAM coupling. By exploiting the chiral anomaly and Chiral Magnetic Effect, we outline coherence mechanisms, decoherence mitigation strategies, and experimental validation protocols. Supported by preliminary data and a rigorous theoretical foundation, this framework envisions fault-tolerant, energy-efficient quantum computing at room temperature, with applications in cryptography, quantum simulation, and global quantum networks.
