D-Wave stock price soars double digits as quantum computer shares rally again today. Here’s why

Shares in major quantum computer companies were on the rise again in premarket trading on Tuesday, highlighting what has been a volatile couple of weeks for a nascent industry that continues to captivate. Here’s what’s driving the latest news:

D-Wave announces Advantage2

By far, Palo Alto-based D-Wave Quantum Inc (NYSE: QBTS) is seeing the biggest boost in premarket trading, with its stock up more than 12% as of this writing. This boost follows a 7% increase in D-Wave shares on Monday.

Investors are likely excited by news on Tuesday morning in which D-Wave announced the general availability of its sixth-generation Advantage2 quantum computing system, which the company says has a demonstrated ability to solve deeply complex problems that classical computers can’t.

“It’s what everybody aspired to achieve, and we’re quite excited about it,” CEO Alan Baratz told Fast Company in March, when the company announced that it had achieved “quantum supremacy” using the Advantage2.

Although some researchers have challenged D-Wave’s claims, investors appear to be on board for now. Shares in D-Wave are up 36.84% year to date.

Quantum Computing Inc rises, falls, and rises again

Hoboken-based Quantum Computing Inc. (Nasdaq: QUBT) has seen some volatility since it released its first-quarter 2025 earnings report last Thursday.

The company swung to a profit, reporting net income of $17 million, versus a net loss of $6.4 million last year. Shares surged double digits on Friday after the report, but then fell more than 8% on Monday, possibly due to some profit taking from investors who wanted to lock in their gains.

Now, in premarket trading on Tuesday, QUBT is back on the rise again, with the stock up almost 9% as of this writing. Who can keep up?

Rigetti Computing Inc: Along for the ride?

Shares in Rigetti Computing (Nasdaq: RGTI) were also on the rise in premarket trading Tuesday, up nearly 6% as of this writing.

The Berkeley-based company has not announced any news this morning that would impact the share price, so it’s possible that investors are just showing a bit more excitement for the quantum computing space. Experts believe the space has the potential to transform computing as we know it, although debates persist about how far we are from widespread practical uses for quantum computing.

It’s worth noting that while all three of the above quantum computing companies are enjoying a rally this week, shares in Quantum Computing Inc. and Rigetti are both down significantly year to date: 36.94% and 39.75% respectively.

Only time will tell if these three stocks will continue on their upward path this week and into the future. For now, enjoy the quantum leap.
