We can finally fix quantum computer glitches by just looking at the different 'personalities' of the background noise.

The Takeaway
Quantum chips are incredibly sensitive to noise, which usually makes their answers unreliable. This method avoids heavy math by running the same task in different spots on the chip, using the specific flaws of each area to cancel out the interference and reveal the correct result.
From the abstract
Near term quantum processors operate in a noise dominated regime, motivating error mitigation techniques that recover accurate expectation values without full fault tolerance. Zero Noise Extrapolation (ZNE) is a widely used but biased error mitigation method that lacks rigorous error bounds. Its effective application requires nontrivial technical choices, most notably the selection of noise scaling factors and extrapolation models, making ZNE sensitive to user expertise and often necessitating c
