What the article says around this equation
The reason NISQ-era hardware imposes such a hard ceiling on quantum machine learning specifically is a simple compounding effect. If a device executes a circuit of N sequential gates, each with per-gate fidelity 1- , and errors accumulate independently, the probability the whole circuit runs without error falls off as
