Abstract: 

In the last few years, there has been tremendous progress in the field of quantum computation. However, its practical realization faces challenges due to various sources of error, with decoherence being one of the most important[1]. In topological quantum computation, both the encoding and processing are inherently resilient against these errors due to their topological nature. Thus, it becomes a potential approach for the realisation of fault-tolerantquantum computers[2,3,4].

In this talk, I will review the fundamental ideas and concepts behind quantum computation. I will discuss its advantages and limitations. Then I will introduce topological quantum computation to overcome these limitations. I will finally present potential physical platforms to realize topological quantum computers.
