Three flip fractions separate channel error rate from source shot count.
Three flip fractions separate channel error rate from source shot count. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.
highlighted = computed this step
One tenth flip moves ten shots
The source total stays 100. A flip fraction of 1/10 moves 10 shots into the one bucket.
100⋅101=10
One fifth flip moves twenty shots
The base channel fraction 1/5 moves 20 shots and leaves 80 shots in zero.
100⋅51=20
Three tenths flip moves thirty shots
At flip fraction 3/10, the same 100 source shots produce 70 zero and 30 one shots.
