Quantum computing stocks are wrapping up a big week of double-digit gains.

Shares of Rigetti Computing, D-Wave Quantum and Quantum Computing have surged more than 20%. Rigetti and D-Wave Quantum have more than doubled and tripled, respectively, since the start of the year. Arqit Quantum skyrocketed more than 32% this week.

The jump in shares followed a wave of positive news in the quantum space.

Rigetti said it had purchase orders totaling $5.7 million for two of its 9-qubit Novera quantum computing systems. The owner of drugmaker Novo Nordisk and the Danish government also invested 300 million euros in a quantum venture fund.

In a blog post earlier this week, Nvidia also highlighted accelerated computing, which it argues can make “quantum computing breakthroughs of today and tomorrow possible.”

Investors have piled into quantum computing technology this year, as tech giants Microsoft, Nvidia and Amazon have embraced the technology with a wave of new chip announcements, multimillion-dollar investments and research plans.
