摘要
Topological states of matter,which have seen rapid development since the last few decades,are characterized by the presence of robust boundary modes.In 2001,Kitaev[1]identified a particularly important example of such topological modes at the ends of a one-dimensional(1D)p-wave superconducting chain(now also known as the Kitaev chain).Due to the presence of particle-hole symmetry in the system,the obtained topological edge modes are pinned at zero energy and are related to the sought-after Majorana particles.Such Majorana zero modes are promising for robust quantum information processing due to their ability to encode qubits nonlocally.Since then,studies of Majorana zero modes and their quantum computing applications have developed into an active research area of their own.
