Axial-Geometric Fermi-Arc Qubits
The project introduces a novel quantum computing architecture that leverages the unique properties of Weyl semimetals to create highly stable qubits. By utilizing strain-induced axial gauge fields rather than traditional electromagnetic controls, the design naturally shields the circuit from common sources of environmental noise.
The proposed research focuses on trigonal as the primary material candidate due to evidence of localized superconductivity on Fermi-arc surface states. The core architecture functions by converting Weyl-node chirality into a noise-orthogonal superconducting circuit, establishing an "axial-geometric sweet manifold" that suppresses first-order responses to conventional charge, flux, and electrostatic chemical potential fluctuations. The text outlines a comprehensive theoretical pipeline from strained first-principles electronic structure calculations to microscopic Josephson spectra and circuit quantization.
