I’m an experimentalist at Microsoft Quantum who was involved in the work presented in our recent Nature publication. As an experimentalist, I can say these results are very exciting and would emphasize that the data are coming from real devices in the lab, not just theories. In the Nature paper, we present data from two different devices to demonstrate that the results are reproducible, and we performed additional measurements and modeling described in the supplemental material to rule out potential false positive scenarios.

In my opinion, the citations above do not represent a balanced view of the Majorana field status but are rather negative. We published two experimental papers recently that went through a rigorous peer review process. Additionally, we have engaged with the DARPA team to validate our results, and we actually have them measuring our devices in our Redmond lab.

Finally, we have exciting new results that we just shared with many experts in the field at the Station Q conference in Santa Barbara. These new experiments further probe our qubits and give us additional confidence that we are indeed operating topological qubits. We will share more broadly at the upcoming APS March meeting.
