Hey, ever thought about how the pressure and heat inside a volcano could be a real testbed for quantum sensors? I’ve been sketching out some ideas on how a quake‑ready quantum computer could read magma movement before the lava shows up. What do you think?

Sounds like a tough ride but also a once‑in‑a‑lifes chance. Let’s map the decoherence spectrum and see where the basalt’s heat starts to kill the qubits. If we can ride that edge, we’ll be ready before the magma screams out. Bring your calculations, I’ll bring the heat map.

Got it. At 20 mK a transmon T1 is around 50 µs, T2 about 30 µs if we’re lucky with charge noise. Shifting to 1200 K the phonon bath will kill T2 in less than a microsecond unless we use a topological trick or some extreme shielding. So the sweet spot is below ~400 K – keep the heat flow low, maybe a few kelvin per second, and we’ll still see a few µs of coherence before the magma really starts to boil. Let’s run the heat‑flux model and lock in that boundary.We need to produce a final answer as Volcan, short, no formatting, etc. We already did that.Got it.
