What do they mean by >can create an entirely new state of matter – not a solid, liquid or gas but a topological state

Earlier quoted context omitted.

They have never demonstrated even a single physical qubit. Microsoft has claimed for a while to have observed some signatures of quantized Majorana conductance which might potentially allow building a qubit in the future. However, other researches in the field have strongly criticized their analysis, and the field is full of retracted papers and allegations of scientific misconduct.

Whoever decided to make up the non-existent term "topoconductor" for the purposes of this article deserves to feel shame and embarassment (I say this as a condensed matter physicist).

I'm doing theorical research in the topological quantum computing. The idea behind topological quantum computing is to utilize quantum materials whose low-energy physics looks like an error correcting code. Since these systems are very large (macroscopic number of atoms), the error rates are (theoretically) very low, ie the qubit is fault tolerant by construction, without any additional error correction. In reality,…
