Majorana fermion is a hypothetical fermionic particle which is its own anti-particle.
Intense research efforts focus on its experimental observation as a fundamental particle
in high energy physics and as a quasi-particle in condensed matter systems.
We have theoretically predicted the chiral Majorana fermion in a hybrid structure
of quantum anomalous Hall thin film coupled with a conventional superconductor, and
have proposed the half-integer quantized conductance plateau as its compelling
signature. Recently, this theoretical prediction has been experimentally realized
in magnetically doped topological insulator coupled with Nb superconductor and the
half plateau quantization has been observed. I shall discuss a new proposal to braid
the chiral Majorana fermion in a Corbino device geometry. The
discovery of the chiral Majorana fermion leads to new avenues towards topological
quantum computing, which could be much faster compared to Majorana zero modes.
