A Google researcher’s paper claiming to have achieved quantum supremacy, a major early milestone in the field of quantum computing, appeared on a NASA website this week before being removed, the Financial Times reports.

Though this announcement is not official, scientists and industry experts have long expected Google to build a quantum computer capable of reaching this milestone—a quantum computer performing a calculation that a classical computer can’t.
