IBM scientists have rejected Google researchers’ claim to have achieved “quantum supremacy,” a demonstration that a quantum computer can vastly outperform a traditional one on a particular task. They contend in a blog post published Monday evening that “the goal has not been met.”
Google’s supposed milestone achievement became public last month when a preprint scientific paper accidentally leaked on the website of NASA, a collaborator, as Fortune reported at the time. Google has said nothing about the potentially historic experiment since then, lending credence to whispers that its researchers are bound to silence under the terms of a news embargo by a major science journal, unable to disclose more information until a certain date which is presumed to be imminent.
