Back Cover: Purity-Assisted Zero-Noise Extrapolation for Quantum Error Mitigation (Adv. Quantum Technol. 12/2024)
Zero noise extrapolation (ZNE) is a method that amplifies and extrapolates noise to a noise-free point. The cover image shows a modified method called purity-assisted ZNE (pZNE). This method enhances the effectiveness of ZNE by accumulating the noises with the forward and backward evolutions to extrapolate the ideal expectation from noisy expectations along the purity of the noisy output state to the ideal pure state. For further details, see article number 2400150 by Kai Xu, Heng Fan, and co-workers.
