[eigenket]

I'm not sure what that has to do with my previous comment but yeah, pushing the boundaries of science is kinda difficult and you can make mistakes.

My understanding is that they pretty convincingly showed that the thing they built acts as a qubit. This means that if its not doing what they think its doing (the "topological" / Majorana stuff) then they accidentally made a qubit which works some other way. That isn't outside the realm of possibility but it is fairly unlikely.
