Shares of Google parent Alphabet soared as much as 6% on Tuesday after the company teased a major breakthrough with its new quantum computing chip “Willow.”

The launch coincides with Google's ongoing DOJ back and forth. In August, a federal judge ruled that Google's search engine practices violated antitrust laws, labeling the company an illegal monopoly. The DOJ has proposed remedies that could include the divestiture of key assets such as the Chrome browser and the Android operating system.
