"...
a Leipzig-based startup spun out of Universität Leipzig (Germany) in 2021, just announced two diamond-based quantum processors — the SXQ128 (128 qubits) and SXQ512 (512 qubits) 
...
The technology hinges on nitrogen-vacancy centers — point defects in synthetic diamond where a nitrogen atom and an adjacent gap in the crystal lattice form a spin qubit that maintains coherence for milliseconds at room temperature. Well-documented physics, in other words. The manufacturing was the wall.

Historically, only 1 to 10 percent of implanted NV centers actually worked. Think of it like running a chip fab where nine out of ten processors come off the line dead — for thirty years straight. SAXON Q reports its patented sulfur co-implantation process pushes that yield above 85 percent, enabling the dense, predictable qubit arrays needed for scalable production. Gate fidelities reportedly hit 99.92 percent, meaning fewer than one error per thousand operations.

WoodScientist, DomeGuy,

i'm sorry to see your mutual irritation and just want to say you both know so much more than the average stupid person like me.
You are both going into subtle details in this matter.
... if it helps settle your differences, please find in me an absolute jerk who would say the following :
Sport isn't important at all and most people giving it any thought other than keeping in shape and being happy are going the wrong way. Sports in television or for money + professional sport in my view is useless and counterproductive.

Please enjoy your similarities.
