The Present and Possible Future of Quantum Computing

I will review the state of quantum computing research, focussing on leading technologies and approaches. One approach in particular, topological quantum computing, is poised at the forefront of physics. This approach aims to create a new kind of delocalized state in a condensed matter system, the so-called Majorana zero mode, that will allow quantum information to be manipulated by braiding particles around one another. The state has been found. Can it be braided?
