A readout shift becomes a classical bit by an exact threshold rule. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.
highlighted = computed this step
A state shift moves the resonator index
The base index is 8 and the shift is 2, so the observed index is 10.
8+2=10
Above the threshold reads bright
The threshold is 9. Observed index 10 reads bright, so the result bit is 1.
