A proposal for a transistor-based quantum computing architecture that uses symmetry-protected topological order to enable noise-resistant Clifford gates without active error correction.
In magnetically textured Josephson junctions the topological regime hosts Majorana bound states coexisting with robust odd-frequency equal-spin triplet pairing that shows 1/ω divergence when Majoranas are decoupled.
The paper identifies four key hurdles in the transition from NISQ to FASQ quantum computers and argues that targeting them will accelerate progress toward useful quantum advantage.
Rashba spin-orbit coupling is presented as essential for engineering topological superconductors with Majorana zero modes that could support protected qubits.
