Non-Abelian braiding of Majorana zero modes in B-form single-stranded DNA with s-wave superconductor

Year: 2025

Type: article

Abstract: We investigate the non-Abelian braiding of Majorana zero modes (MZMs) in one-dimensional topological superconducting B-form single-stranded DNA (ssDNA). An effective model is proposed for the braiding of MZMs by utilizing a quantum dot(QD) and locally tunable gates. We illustrate the process of constructing state initialization and measurement by manipulating the coupling strength . Importantly, MZMs can maintain stability during the braiding process, which demonstrates that the other states can be entirely prevented from mixing with MZMs in ssDNA. We also apply this approach to detect MZMs in topological superconducting ssDNA. Our proposal provides a novel approach to experimentally confirm the non-Abelian statistical properties of MZMs in organic molecules.
