We present an algorithm that builds on the reduction to Population Recovery introduced in [FO21]. Addressing an open question from that work, our algorithm has the key advantage of robustness against even severe state preparation and measurement (SPAM) errors. To tolerate SPAM, we must analyze Population Recovery on a combined $Z$-channel/bit-flip channel, which necessitates extending the complex analysis techniques from [PSW17, DOS17].
