Axial-Geometric Fermi-Arc Qubits

Rihaan Shah
Updated 8/8/2026

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 PtBi2\text{PtBi}_2PtBi2​ 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.
