Quantifying Non-Abelian Stability in Majorana Qubits through Rabi Beating Signatures
Yu Zhang, Jiayi Chen, Jie Liu +1
Evaluating the stability of Majorana qubits (MQs) is a central challenge for topological quantum computation. Here we propose a simple and experimentally accessible protocol to qua…
Shot noise signatures identifying non-Abelian properties of Jackiw-Rebbi zero modes
Haoran Ge, Zhen Chen, Yijia Wu +1
Jackiw-Rebbi zero modes were first proposed in 1976 as topologically protected zero-energy states localized at domain walls in one-dimensional Dirac systems. They have attracted wi…
Three-Majorana Cotunneling Interferometer for Non-Abelian Braiding and Topological Quantum Gate Implementation
Zhen Chen, Yijia Wu, X. C. Xie
We propose a novel scheme for performing Majorana zero mode (MZM) braiding utilizing cotunneling processes in a three-MZM system incorporating reference arms. This approach relies…
Unified model for non-Abelian braiding of Majorana and Dirac fermion zero modes
Tianyu Huang, Rui Zhang, Xiaopeng Li +3
Majorana zero modes (MZMs) are the most intensively studied non-Abelian anyons. The Dirac fermion zero modes in topological insulators, which are symmetry-protected doubling of MZM…
Quantifying the non-Abelian property of Andreev bound states in inhomogeneous Majorana nanowires
Yu Zhang, Yijia Wu, Jie Liu +1
Non-Abelian braiding is a key property of Majorana zero modes (MZMs) that can be utilized for topological quantum computation. However, the presence of trivial Andreev bound states…
