根據外電報導，處理器大廠英特爾 (Intel) 的研究人員透露，該團隊正在測試一種微小的新型量子芯片，以推動量子計算機的發展邁進新的里程碑。
報導指出，這種新型量子芯片是在英特爾位於美國俄勒岡州的 D1D Fab 工廠中所製造出來的。它使用了英特爾過去製造出數十億片傳統計算機芯片相同的矽製造技術來生產。不過，該款量子芯片卻比英特爾製造出的傳統芯片要小的多，面積比鉛筆頭上的橡皮擦還要小。
報導進一步指出，量子芯片不含構成當今計算設備基礎的晶體管，而是包含可以容納一個單電子的量子位。在單電子同時處於多個旋轉狀態，或其他行為時所帶來的計算能力將比當前的晶體管效益要大得多，而單電子行為也是量子計算的基礎。
英特爾指出，新的微型量子芯片的特點有著無限潛力。其中包括它的量子位極小，寬度約只有 50 奈米，只有在電子顯微鏡下才能看到。在這樣小的寬度下，一根頭髮的直徑可以讓約 1,500 個量子位通過。而在這樣的特性下，英特爾量子芯片未來的設計將可以大幅度的擴展。這使得未來的量子計算機將包含數千，甚至數百萬個量子位，其計算能力要將比當前全球最快的超級計算機要強大得多。 (新聞來源: 科技新報)
