The passage around this formula
…anchored to a cited, checkable piece of theory, and the crossover tolerance is computed, not chosen after the fact to produce a headline. What is a choice, and should be named as one, is treating and as commensurate just because both are dimensionless numbers between zero and one. A fidelity and a normalized angular tolerance measure different things, and no law of physics says a “demanding” qubit fidelity and a “demanding” compass tolerance sit at the same point on their respective…
