Speaker: Dr Henry Legg (St Andrews) Abstract: Recently, significant attention has been focused on realising a topological qubit based on Majorana zero modes, driven in particular by claims from Microsoft Quantum. Here, I critically examine the Topological Gap Protocol (TGP) and demonstrate its fundamental Blind Spots. I show that the TGP is unreliable both as a diagnostic tool for topological superconductivity and associated Majorana zero modes, and as a method for verifying a bulk superconducting gap — a prerequisite for parity readout and qubit operation. Based on these insights, I will con…
