Zhao et al., “Realization of an error-correcting surface code with superconducting qubits,” Phys. These results bring us a step closer toward realizing a practical quantum computer.”īoth groups have recently published papers on their work: Y. Now, two groups, led by Jian-Wei Pan at the University of Science and Technology of China in Hefei and Andreas Wallraff at the Swiss Federal Institute of Technology (ETH) in Zurich, have achieved the first-ever demonstration of error correction with surface codes. But until now, demonstrations with the surface code have only detected errors, not corrected them. There’s a short, excellent account of the work (Error-Correcting Surface Codes Get Experimental Vetting) written by Luigi Frunzio and Shraddha Singh and posted today on the APS physics website.Īs explained by the authors, “These codes are promising because they are experimentally straightforward to implement and because, under certain conditions, they can tolerate relatively large error rates. Recently, separate teams of researchers reported progress in demonstrating not only error detection but also error correction using so-called surface codes. Robust quantum error correction (QEC) is a necessary ingredient for achieving practical quantum computing and as you might expect there’s an abundance of ongoing work in the area.
