What does early FTQC mean? It seems to be an increasingly popular term, but usage seems to split into two camps.
One is FTQC but early. So you have logical qubits with a decent distance, magic state production to support logical non-Cliffords. It's just early because you don't have a lot of it.

Quantum computers require magic to run useful algorithms. But classically benchmarking fault-tolerant magic operations is intractable.
In new work, led by PhD student Yugo Takada, we introduce an efficient classical algorithm to exactly simulate a broad class of fault-tolerant magic operations.

It also makes me wonder which type of hardware will be acoustically noisy: NISQ or FTQC.
I'm thinking that it's got to be FTQC: industrial-scale machines to turn quantum noise into acoustic noise.

Our work shows that all layers of FTQC are vital in the quest of quantum advantage. We reduce the runtime making the quantum computation feasible, challenging classical methods and resulting to a predicted runtime quantum advantage.

To me these seem pretty different. One is about finding and correcting all the errors, and so is proper FTQC. Even if it is early days.
The other is more about detecting and avoiding errors, and probably paying a sampling overhead to ignore them once you find them. So still a form of mitigation.
