Can someone check my understanding: does this mean they have eight logical qubits on the chip? It appears that way from the graphic where it zooms into each logical qubit, although it only shows two there.
If that is true, it sounds like having a plan to scale to millions of logical qubits on a chip is even more impressive.
- fsh 2y agoThey 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.

- tmvphil 2y agoThey have no qubits at all, "logical" or not. yet. They plan to make millions. It is substantially easier to release a plan for millions of qubits than it is to make even one.
