Performance: A Brutal Start to 2026 Rigetti is down 27.36% year-to-date and 37.44% over the past month. The stock peaked at $58.15 in mid-October but has since given back most of those gains. For context, the one-year return still sits at 31.35%, but momentum has clearly reversed. The company trades at a 660x price-to-sales ratio with $7.49 million in trailing twelve-month revenue and a $4.95 billion market cap.
The quantum computing stocks boomed for most of 2025, only to go bust in the last quarter. In 2026, it's been mostly looking lower for many of the top quantum plays, including some of the more speculative plays. That said, the technology is still worth keeping tabs on, even as the quantum pure-play stocks continue to take more backward steps. Of course, investors have taken on more of a risk-off approach in the past couple of quarters.
As investors turned their back on software (notably, the seat-based software-as-a-service companies), they're turned towards hardware in a big-time way. You wouldn't know it by looking at those flat shares of Nvidia ( NASDAQ:NVDA), but the iShares Semiconductor ETF ( NASDAQ:SOXX) is up around 13% year to date, with few signs of slowing down. The winners within semis have been broad, but the undisputed kings of the 2026 semiconductor surge belongs to the memory and storage stocks.
The effort comes as competition for AI talent intensifies worldwide and tech workers in the US grapple with layoffs, burnout, and visa complications. According to BCG's 2024 talent tracker report, the US remained dominant in attracting AI talent worldwide. Already known for its tech scene, Finland, with a population of around 5.6 million, is positioning itself as a place where American tech workers can find a better work-life balance without sacrificing their careers - a notable contrast to the famous grindset of Silicon Valley.
A team based at the University of Vienna put individual clusters of around 7,000 atoms of sodium metal some 8 nanometres wide into a superposition of different locations, each spaced 133 nanometres apart. Rather than shoot through the experimental set up like a billiard ball, each chunky cluster behaved like a wave, spreading out into a superposition of spatially distinct paths and then interfering to form a pattern researchers could detect.
Cisco aims to "build high-fidelity quantum networks to unlock the potential for large-scale quantum data centers," Kompella told Telecompetitor in an interview. The company is working closely with IBM on the research, with IBM's role focused primarily on the computing side, while Cisco tackles the networking side. Quantum computers use concepts of quantum physics. They're more powerful than traditional non-quantum computers, known in quantum jargon as "classical" computers. But, as of today, there is no way to network quantum computers.
I have been thinking about the future and how we might respond to it. We are sliding into a period of transition like no other, most likely triggered in three waves; AI, quantum computing and the brain computer interface. Artists have a role to look into the mists and, when they catch sight of something, to hold up a mirror.
Nowadays, we're told quantum computing will be the next big thing. All with the ability to solve problems far too complex for typical computers within minutes, or even seconds. In fact, "Overall, the global quantum computing market is expected to grow from $1.6 billion in 2025 to $7.3 billion by 2030, according to BCC Research. That represents a compound annual growth rate of 34.6% over the next five years," added U.S. News & World Report.
If you don't mind peering through a sheet of glass, you can see a Quantum Computer at IBM's office in Waterloo. Known as the IBM Quantum System One, it is the first circuit-based commercial quantum computer, launched by IBM in January 2019. Quantum computers are capable of using the weird world of quantum physics and simplistically, where a standard computer bit can be either a binary One or Zero, a quantum computer can be both at the same time.
In this week's edition of Computer Weekly, we take a closer look at reports of low workplace morale within the Police Digital Service, as its staff eagerly await the outcome of the long-promised Home Office's policing reform whitepaper. Jérôme Goulard, the chief sustainability officer of Orange Business, talks us through the work he is doing to balance business objectives with IT sustainability within the organisation.
On Friday, Quantum Computing Inc. released its third-quarter 2025 financials-and the company announced an unexpected earnings and revenue beat. As noted by Investor's Business Daily, Quantum Computing reported earnings per share of 1 cent. Investors had been expecting the company to post a 6-cent-per-share loss. The company also reported revenue for the quarter of $384,000. Analysts had been expecting revenue of just $100,000.
"Government intervention in the economy in the name of national security is most clearly warranted in cases of market failure," a new report from a bipartisan task force organized by the Council on Foreign Relations says. "Today, the market failures that loom largest for U.S. national security are shortfalls of private capital in strategically important areas and over-concentration of critical supply chains in unfriendly countries," the report adds.
Instead of looking for the "next" artificial intelligence (AI) stock, some traders are turning to quantum computing stocks for big price moves. Among the best-known publicly listed quantum computing firms is Rigetti Computing ( NASDAQ:RGTI), and its stock is trending right now. There's even talk that AI technology king NVIDIA ( NASDAQ:NVDA) is getting involved in the quantum computing field. So, you may be ready to hit the "buy" button and load up on RGTI shares - but not so fast.
Quantum computing stocks have been surging nonstop over the past year. Stocks like , and have corrected recently, but the market has seen several such corrections that were followed by an even bigger surge. It seems that quantum computing businesses have found themselves in the midst of a perfect storm of events, something that could actually make them sustainable. It's no secret that Wall Street now sees quantum computing as the next logical "big thing" after AI.
has been on a rally that exceeded bullish expectations several times over. This is largely thanks to the company's management pulling off a PR offensive and then turning it into a windfall for the company's balance sheet. In turn, investors got even more bullish, and QBTS stock has been on a relentless rally. All that said, the past month has been less bullish. QBTS stock is only up 1.2% in the past month after falling from its peak.
