Braiding Majorana zero mode in an electrically controllable way

نویسندگان

چکیده

To realize the braiding operations of Majorana zero mode in vortex cores a topological superconductor (TSC), novel approach is proposed this letter to replace common tip (or tip-like) method. Instead on top TSC thin film, arrays electrically controllable pining centers are built beneath hence detecting can proceed along with braiding. It does not only increase rate, but also enables be performed an way and integrated into large scale. Our work paves towards large-scale quantum computation.

Braiding With Majorana Fermions

This paper is an introduction to relationships between topology, quantum computing and the properties of fermions. In particular we study the remarkable unitary braid group representations associated with Majorana fermions.

Majorana Braiding with Thermal Noise.

We investigate the self-correcting properties of a network of Majorana wires, in the form of a trijunction, in contact with a parity-preserving thermal environment. As opposed to the case where Majorana bound states are immobile, braiding Majorana bound states within a trijunction introduces dangerous error processes that we identify. Such errors prevent the lifetime of the memory from increasi...

Braiding properties of Majorana Kramers pairs

We consider the braiding of Kramers pairs of Majorana bound states. We derive the most general transformation on the many-body ground state that is applied as the result of such a braiding process. The result is derived in the context of a toy model, but we will show that it has the most general form that is compatible with local and global conservation of electron parity. In accordance with ea...

New scheme for braiding Majorana fermions

Non-Abelian statistics can be achieved by exchanging two vortices in topological superconductors with each grabbing a Majorana fermion (MF) as zero-energy quasi-particle at the cores. However, in experiments it is difficult to manipulate vortices. In the present work, we propose a way to braid MFs without moving vortices. The only operation required in the present scheme is to turn on and off l...

Distinguishing a Majorana zero mode using spin-resolved measurements.

One-dimensional topological superconductors host Majorana zero modes (MZMs), the nonlocal property of which could be exploited for quantum computing applications. We use spin-polarized scanning tunneling microscopy to show that MZMs realized in self-assembled Fe chains on the surface of Pb have a spin polarization that exceeds that stemming from the magnetism of these chains. This feature, capt...
