Most of a fault-tolerant computer makes magic states
A resource estimate quoted as a qubit count is usually quoting the smallest part of the machine.
First, commit to an answer
A circuit needs 4 logical qubits and a handful of T gates. Roughly what fraction of the physical machine holds the algorithm?
Decide before you follow the link. Nothing is recorded — the value is in having been wrong on purpose once.
Now go and look
Read the fault-tolerant panel: the layout table, the prefactor table, and the factory note.
What you should see
A few percent. Magic-state factories are typically the majority of the machine, and the panel also shows that two equally conventional constants change the answer by 2.78×.
