A few years ago, the first signs of a new emergent particle — Majorana modes — were obtained. It was an exciting development because Majoranas are predicted to show nonabelian particle-exchange statistics, which would be a first for any physical system. As if that weren’t enough, another motivation to develop this experimental observation into a controlled electronic device is that the use of topology in such systems is expected to yield unrivalled coherence in topological qubits made from Majoranas. The experimental situation is that we aren’t there yet, not because of unforeseen problems — in fact, the foreseen problems are hard enough. This talk will address where things stand, how’s the qubit, what are the challenges, and what is the future of this unconventional approach to quantum information.
