Quantum interference in the QAHI–TSC–QAHI–TSC Corbino junction. (A) The Corbino junction consists of a Corbino QAHI ring with a fan-shaped $s$-wave superconductor on top of it which drives regions II and IV into the TSC, and a voltage gate $V_G$ is added at the bottom edge. (B) Such a junction is equivalent to a series of single-qubit quantum gates $ZH{R}_{{\varphi }_G}ZH$, where $R_{{\varphi }_G}$ is a phase gate controlled by $V_G$. (C and D) The MZM braiding process that gives the same gates as the Corbino device with ${\varphi }_G=0$ and ${\varphi }_G=\pi /2$, respectively.
