Why this site exists

I spent the better part of a decade measuring how long a single spin in silicon carbide stays coherent before the world knocks it out of phase. Coherence time is the quantity that decides whether a quantum device is a curiosity or a tool. It is also, it turns out, a decent metaphor for everything I now care about writing down.

This site is where I do that writing. Not threads, not slides — a stable domain with proper structure, meant to still be readable in 2034. The reason is simple: hot takes on rented platforms decay, and the things I find genuinely interesting about quantum technology, AI, and industry are the slow things. They reward being written once, carefully, and left to compound.

I am not here to explain quantum mechanics to you. There are people who do that well, and it isn’t my role. My role sits on a narrower line: I have spent years as a researcher in spin defects, and I am now helping build a company around the unglamorous problem of measuring those defects reliably. That puts me between two rooms — the lab and the market — and most of what I want to write is about what you can see when you stand in the doorway between them.

So the writing here splits four ways:

• Paper Perspectives — a recent paper, put in context. Not a summary; an argument about why it matters, or why it doesn’t.
• Fundamentals — the durable physics of spin defects, built up properly, for readers who want the real thing rather than the press release.
• Industrial Reality — what actually happens when a measurement leaves the optical table and has to survive a customer, a budget, and a deadline.
• Personal Notes — this. Shorter, first-person, lower stakes. What I’m thinking about, what I got wrong, what changed my mind.

You’re reading the first Personal Note, which means I should be honest about the state of things: most of those pillars are still empty as I write this. That’s deliberate. I would rather start with the connective tissue — why I’m doing this, how I think — than open with a flagship essay I can’t yet follow up on. A publication that posts once and goes quiet is worse than one that starts small and keeps its word.

The bar I’m holding myself to has three questions. Would a researcher in my own field read a piece and find no sloppiness? Would someone from industry leave with a sharper view of the world, not just an impressed one? And will the piece still be honest and findable ten years from now? If the answer to any of those is no, it doesn’t ship.

That’s the whole idea. Quantum, AI, and the place where they meet industry — written slowly, owned outright, and meant to last. Welcome.
