Microsoftの量子コンピューター構築のカギだった「マヨラナ粒子」を観測したという論文が撤回される

 量子コンピューターの分野において、GoogleやIBMがプロトタイプを構築する中で出遅れていたMicrosoftは「マヨラナ粒子」を利用した量子コンピューターの構築を進めていました。
 2018年に発表された、超低温半導体ワイヤにおいてマヨラナ粒子の存在する証拠を観測したという論文は、Microsoftの動きを大きく後押しするものでしたが、このたび、論文を発表した研究チームが新たな論文を発表し「マヨラナ粒子は観測できなかった」と結論を改めました。

 2018年3月、デルフト工科大学の応用物理学教授でMicrosoftにも籍を置くレオ・クーヴェンホーフェン氏は、Hao Zhang氏らとともに、捉えどころのない粒子であると考えられていた「マヨラナ粒子」を観測したという論文を発表しました。
