FTQC at Pasqal
Yes, or arxiv.org/abs/2509.18294 which is a follow up .
Both refer to "early fault-tolerant" concept in their abstract, but I concur that "partially" is more appropriate!

But I don’t think there is a well-defined, shared meaning. It’s a bit of a tote bag right now.

For example, rely on non-FT circuitry and post-select on it.
This is done in the STAR architecture papers to perform small Z angle rotations in surface codes by “direct” non-FT initialization of magic states, through local rotations on the support of the logical operator.

Another possible meaning is you work with encoded qubits, but you are allowed to cut corners and rely on non-scalable techniques tailored to your workload, made available by the smallish circuits and the low code distances.

Yeah, states get close through a noisy Clifford circuit, what else to expect?

And after all an encoded qubit is like a qubit. Logical memory error rate will converges to 0.5, just slower.

If benchmark performance translated to reality, radiologists should be the canary in the coal mine of AI job loss.

Instead, radiology residency slots hit a record high in 2025.

Similar to me is: paper consumption kept growing when digital word processors appeared, as they eased the production of documents. Only recently local stagnation was observed, that we can attribute to the overall digitization of processes.

The Convention on Biodiversity, GM trees and paper consumption
The CBD report on GM trees recommends a precautionary approach to the use of GM trees. A ban would be better.

perhaps making topological qubits when you know you don't have Majorana?

It's really programming without fear.

Then even more comfy to jj new on the _unreachable_ commit discarded by the op to open it in a buffer.

pop up jj op log
find a snapshot op in the past where I guessed the file still existed
jj file show --at-op <OP_ID> my_file

It's there 📍

But we have not spared our efforts on digital and QEC in the past year, and so we will join the database very soon! 😀

You may have noticed that Pasqal is not on the map though... And indeed, for a time we had operated our devices in the analog mode only.
