Google’s recent announcement of the arrival of Willow, a quantum chip that has reduced the error tendencies of some of its predecessors, is a milestone in the effort to bring quantum computing into the real world, and in the years ahead, it could change the way we think about the risk in cryptocurrencies.

Willow’s speed is almost incomprehensible — according to Google, it’s able to perform a computation in under five minutes that would take one of today’s fastest supercomputers 10 septillion years to solve. Ten septillion is 10,000,000,000,000,000,000,000,000 years.

But the accuracy of quantum computing has, until now, also been a big issue, with quantum like a garden hose on full blast with no one holding it: the water is coming out fast, but its aim is not consistently accurate. Willow’s combination of speed and accuracy could theoretically provide hackers with the tools to unlock the algorithms that bitcoin and other cryptocurrencies are built upon.

Qubits and bitcoin can coexist, for now 

If you don’t understand (not many people do) what makes up quantum computing — qubits — security company DigiCert’s industry technology strategist, Tim Hollebeek, has a simplified way of thinking about the breakthrough. He says imagine a maze and how a classical computer would try to find its way through the maze from start to finish. It would try one potential path at a time. “A quantum computer would be able to try each path at the same time, resulting in a much faster solution,” Hollebeek said.

While Willow may not be ready for real-world applications yet, Willow’s speed and accuracy will help pave the way for larger-scale quantum computers.

“Part of the issue with qubits is that they are unstable and produce errors. This chip has significant error correction capabilities, which mitigates some of the qubit issues,”  Hollebeek said.

That means chips improving upon Willow’s breakthrough will be able to help hackers target crypto — but at least for the moment, the concern is only theoretical.

“Quantum computers can theoretically solve this much faster and pose a threat to today’s cryptographic algorithms if a quantum computer with sufficient qubits could be developed,” Hollebeek said. But he added that the real-world reason for breathing easier today if you own crypto is simple. “None exist today and are not expected for at least another 5, 10, 15 years,” he said, with the fastest five-year timeline contingent on some unforeseen technological breakthrough.

A decade-long lead for crypto

A Google spokesman told CNBC that Willow and crypto can coexist. “The Willow chip is incapable of breaking modern cryptography,” he said, adding that it is also the view of Google that quantum technology with that capability is still years off.

In fact, according to Park Feierbach, an expert in decentralized finance technology who is CEO of Radiant Commons, even if Willow can drastically increase the speed at which crypto could be broken, it would still take several times the age of the universe for the quantum chip to do it. According to NASA, the universe is 13.7 billion years old.

“There’s almost no reason to deploy Willow on this technology in a way that could make tractable progress. It would simply still take too long,” Feierbach said.

“Estimates are we’re at least 10 years out from breaking RSA, and that around 4 million physical qubits would be required to do this,” the Google spokesman said. RSA is an encryption system used in cryptocurrencies.

For reference, Google’s processors are now on the scale of about 100 physical qubits.

‘Quantum-safe’ algorithms

The Google spokesman stressed that the timeline for quantum breakthroughs has been widely shared and Willow has not changed it.

“Google is on track with our planned roadmap,” he said. “The security community has long been aware of the projected timeline to break asymmetric encryption, and has been working on defining standards and collaboratively implementing new algorithms that will resist attacks by both classical and quantum computers,” the spokesman added.

Indeed, Hollebeek says that the crypto industry is working on “quantum-safe” crypto.

The National Institute of Standards and Technology (NIST) has released several quantum-safe algorithms that are resistant to attacks by future quantum computers, Hollebeek said, and NIST has a timeline for governments and industry to deploy these algorithms to ensure the safety of the nation’s and businesses secrets.

“Google and other industry leaders have supported standardization and experimented with the algorithms in their draft form,” the Google spokesman said.

Despite how efficient quantum is at unlocking algorithms (traditional crypto equations based on factoring huge prime numbers), it isn’t infallible, and that is where the promise lies in quantum-safe crypto.

“They’re really, really good at some things, but not everything,” Hollebeek said, noting that breaking conventional asymmetric cryptography just happens to be one of the things they are really good at. “Luckily, there are other hard math problems they are bad at, and asymmetric cryptography can be updated to use those hard math problems instead of factoring,” he said.

Taqi Raza, assistant professor of electrical and computer engineering at the University of Massachusetts Amherst, said existing cryptos will have to evolve to ward off qubits. “As the potential for quantum computers to break existing cryptography becomes more of a concern, new cryptocurrencies specifically designed to be quantum-safe could be developed. These new quantum cryptos would integrate PQC, cryptographic algorithms that are resistant to the computational power of quantum computers,” Raza said.

Jeremy Allaire, co-founder, chairman & CEO of digital currency company Circle, told CNBC in an interview last week that the risk is real, but his view of the future remains focused on the opportunities that will evolve. “The bottom line is quantum crypto means that you can both unlock things more easily, things that had bad old locks, but you can also create better locks,” Allaire said. “So quantum crypto – this quantum is going to be actually a huge turbocharge to crypto computing, to crypto applications, and to crypto money.”

Raza thinks that ultimately the more sweeping changes wrought by quantum computing will occur beyond crypto. Breakthroughs will make devices and software faster, revolutionize AI, and improve data security with ultra-secure encryption methods. In everyday life, there will be advances in computing, healthcare, energy, and security, Raza said, and as a result, it is not the crypto industry we should be thinking about in isolation while these changes are still developing. “They will likely transform industries,” he said.

Hands-on with the Meta Ray-Ban Display glasses

When it comes to the new $799 Meta Ray-Ban Display glasses, it’s the device’s accompanying fuzzy, gray wristband that truly dazzles.

I was able to try out Meta’s next-generation smart glasses that the social media company announced Wednesday at its annual Connect event. These are the first glasses that Meta sells to consumers with a built-in display, marking an important step for the company as it works toward CEO Mark Zuckerberg’s vision of having headsets and glasses overtake smartphones as people’s preferred form of computing.

The display on the new glasses, though, is still quite simplistic. Last year at Connect, Meta unveiled its Orion glasses, which are a prototype capable of overlaying complex 3D visuals onto the physical world. Those glasses were thick, required a computing puck and were built for demo purposes only.

The Meta Ray-Ban Display, however, is going on sale to the public, starting in the U.S. on Sept. 30.

Though the new glasses include just a small digital display in their right lens, that screen enables unique visual functions, like reading messages, seeing photo previews and reading live captions while having a conversation with someone.

Controlling the device requires putting on its EMG sensor wristband that detects the electrical signals generated by a person’s body so they can control the glasses via hand gestures. Putting it on was just like strapping on a watch, except for the small, electric jolt I felt when it activated. It wasn’t as much of a shock as you feel taking clothes out of the dryer, but it was noticeable.

Donning the new glasses was less shocking, until I had them on and saw the little display emerge, just below my right cheek. The display is like a miniaturized smartphone screen but translucent so as to not obscure real-world objects.

Despite being a high-resolution display, the icons weren’t always clear when contrasted with my real-world field of view, causing the letters to appear a bit murky. These visuals aren’t meant to wrap around your head in crystal-clear fidelity, but are there for you to perform simple actions, like activating the glasses’ camera and glancing at the songs on Spotify. It’s more utility than entertainment.

I had the most fun trying to perform hand gestures to navigate the display and open apps. By clenching my fist and swiping my thumb on the surface of my pointer finger, I was able to scroll through the apps like I was using a touchpad.

It took me several attempts at first to open the camera app through pinching my index finger and thumb together, and when the app wouldn’t activate I would find myself pinching twice, mimicking the double clicking of a mouse on a computer. But whereas using a mouse is second nature to me, I learned I have subpar pinching skills that lack the correct cadence and timing required to consistently open the app.

It was a bit strange and amusing to see people in front of me while I continuously pinched my fingers to interact with the screen. I felt like I was reenacting an infamous comedy scene from the TV show “The Kids in The Hall” in which a misanthrope watches people from afar while pinching his fingers and saying, “I’m crushing your head, I’m crushing your head!”

With the camera app finally opened, the display showed what I was looking at in front of me, giving me a preview of how my photos and videos would turn out. It was like having my own personal picture-in-picture feature like you would on a TV.

I found myself experiencing some cognitive dissonance at times as my eyes were constantly figuring out what to focus on due to the display always sitting just outside the center of my field of view. If you’ve ever taken a vision test that involves identifying when you see squiggly lines appearing in your periphery, you have a sense of what I was feeling.

Besides pinching, the Meta Ray-Ban Display glasses can also be controlled using the Meta AI voice assistant, just as users can with the device’s predecessors.

When I took a photo of some of the paintings decorating the demo room’s halls, I was told by support staff to ask Meta AI to explain to me what I was looking at. Presumably, Meta AI would have told me I was looking at various paintings from the Bauhaus art movement, but the digital assistant never activated correctly before I was escorted to another part of the demo.

I could see the Meta Ray-Ban Display’s live captions feature being helpful in noisy situations, as it successfully picked up the voice of the demo’s tour guide while dance music from the Connect event blared in the background. When he said “Let’s all head to the next room,” I saw his words appear in the display like closed-captions on a TV show.

But ultimately, I was most drawn to the wristband, particularly when I listened to some music with the glasses via Spotify. By rotating my thumb and index finger as if I was turning an invisible stereo knob,
I was able to adjust the volume, an expectedly delightful experience.

It was this neural wristband that really drilled into my brain how much cutting-edge technology has been crammed into the new Meta Ray-Ban Display glasses. And while the device’s high price may turn off consumers, the glasses are novel enough to potentially attract developers seeking more computing platforms to build apps for.

Navan, corporate travel and expense startup, files for initial public offering

By year-end there should be around 20 tech IPOS, says Barclays' Kristin DeClark

Navan, the business travel, payments, and expense management startup, filed on Friday afternoon to go public.

Its S-1 filing with the Securities and Exchange Commission indicates that the company plans to list on the Nasdaq Global Select Market under the symbol “NAVN.”

Navan reported trailing 12-month revenue of $613 million (up 32%) across over 10,000 customers, and gross bookings of $7.6 billion (up 34%), according to the S-1 filing.

Goldman Sachs and Citigroup will act as lead book-running managers for the proposed offering.

Navan ranked No. 39 on this year’s CNBC Disruptor 50 list, and also made the 2024 list.

The IPO market has bounced back this year, with deal activity up 56% across 156 deals (roughly 200 IPO filings in all) and $30 billion in proceeds, up over 23% year over year, according to IPO tracker Renaissance Capital. It has been the best year for IPOs since 2021, though still far below the Covid offering boom years, when over $142 billion (2021) and $78 billion (2020) was raised by IPOs.

This year’s deal flow has been highlighted by hot AI names like Coreweave, as well as some of the startup world’s most highly valued firms from the past decade, such as fintech Klarna and design firm Figma, crypto companies Circle, Bullish and Gemini, and some long-awaited IPO candidates finally hitting the market, such as Stubhub this week, though its shares have slumped since the first day of trading. Top Amazon reseller Pattern went public on Friday.

Other startups are expected to pursue deals given the increased investor appetite.

The Renaissance IPO ETF is up 20% this year.

Launched by CEO Ariel Cohen and co-founder Ilan Twig in 2015, Navan set out to disrupt a business travel sector where incumbents relied on clunky legacy tools and fragmented workflows.

The Palo Alto-based company, formerly called TripActions, refers to itself as an “all-in-one super app” for corporate travel and expenses.

Customers include Unilever, Adobe, Christie’s, Blue Origin and Geico.

It has also been pushing further into AI, with a virtual assistant named Ava handling approximately 50% of user interactions during the six months ended July 31, according to the filing, and a proprietary AI framework called Navan Cognition supporting its platform, as well as proprietary cloud infrastructure.

“We built Navan for the road warriors, for CEOs and CFOs who understand travel’s critical importance to their strategy, the finance teams who demand precision and control, the executive assistants juggling itineraries, and the program admins ensuring seamless events,” the co-founders wrote in an IPO filing letter.

“We saw firsthand the frustration of clunky, outdated systems. Travelers were forced to cobble together solutions, wait for hours on hold to book or change travel, and negotiate with travel agents. They struggled to adhere to company policies, with little visibility into those policies, and after all that, they spent even more time on tedious expense reports after a trip. We felt the pain of finance teams struggling to gain visibility into fragmented travel spending and to enforce policies, and the frustration of suppliers unable to connect directly with the high-value business travelers they sought to serve,” they wrote in the filing.

Revenue grew 33% year-over-year from $402 million in fiscal 2024 to $537 million in fiscal 2025, according to the S-1 filing. The company reported a net loss that decreased 45% year-over-year from $332 million in fiscal 2024 to $181 million in fiscal 2025. Gross margin improved from 60% in fiscal 2024 to 68% in fiscal 2025.

The business travel and expense space is crowded, with fellow Disruptors Ramp and Brex, and TravelPerk, as well as incumbents like SAP Concur and American Express Global Business Travel.

Microsoft said on Friday that it will increase the recommended retail price of several Xbox consoles in the U.S. starting in October because of “changes in the macroeconomic environment.”

The company said it would not increase prices for accessories such as controllers and headsets, and that prices in other countries would stay the same.

While Microsoft didn’t explicitly attribute the increase to the Trump administration’s tariffs, many consumer companies have been warning for months that higher prices are on the way. President Donald Trump has issued tariffs this year on multiple countries with a stated goal to bring more manufacturing to the U.S.

“We understand that these changes are challenging, and they were made with careful consideration,” Microsoft said on its website.

It’s the second time Microsoft has raised prices on its consoles in the U.S. this year. Rivals Sony and Nintendo have also raised console prices in the U.S. as Trump’s tariffs went into effect.

Here are the changes, according to a PDF posted on Microsoft’s website:

  • Xbox Series S will start at $399, up from $379 previously. A version with 1TB of storage costs $449.
  • Xbox Series X Digital console now costs $599, a $50 increase. The Xbox Series X with a disc drive also got a $50 increase to $649.
  • The most expensive version, with 2TB of storage, costs $799, up from $729.
