Quasiparticle eggheads were 'caught up in the enthusiasm of the moment' Katyanna Quach Tue 9 Mar 2021 // 08:55 UTC Share Copy Updated A paper published in Nature two years ago and spearheaded by a Microsoft scientist has been retracted after it emerged that the data presented simply didn't add up. The work was produced at a quantum computer lab set up by Microsoft and QuTech, a research center co-founded by the Delft University of Technology (TU Delft) in the Netherlands. The study, led by Microsoftie and TU Delft Professor Leo Kouwenhoven, reported the discovery of a theoretical quasiparticle the academics believed would prove useful for future quantum computers.
