The passage around this formula
… , the achievable variance scales as 1/(N ) , in contrast to the quadratically better Heisenberg scaling available only when probes are used coherently together [ 13 ] . Modeling the collected radiation up to time t as contributing t/ roughly independent quanta gives, as a stated phenomenological ansatz rather than a first-principles evaporation calculation,
