EMRE achieves this by accepting a small non-zero bias, with an optimal bias computable via resource-theoretic measures. Exact results are derived for depolarizing and dephasing noise models. The paper also introduces Hybrid EMREs (HEMREs), a family of protocols that generalize both PEC and EMRE with a tunable bias parameter, enabling flexible trade-offs between sample complexity and error reduction for near-term and early-fault tolerant quantum devices. ## Full article daily.dev links to this article rather than hosting it.
