IBM Quantum Computing Progress Edges Toward Eventual Utility

Osprey has 433 qubits, the fundamental data processing element inside these weird machines.

In a move that bodes well for quantum computing’s long-term prospects, IBM said Wednesday it’s built a new machine called Osprey with 433 qubits. Tripling the total number of data processing elements compared with last year significantly increases the computational power of the system.

IBM has been working steadily for years to make quantum computing a commercial success, competing against big companies like Google and Intel, earlier specialists like D-Wave and Rigetti Computing, and newer startups like Atom Computing and Pasqal. Quantum computing promises to conquer challenges out of reach of the conventional technology that powers smartwatches and supercomputers.

One of the most promising domains for quantum computing is materials science, where quantum chemistry simulations could improve solar panels, batteries and other devices that operate at the molecular level. But quantum computing fans also hope to bring new tools to AI, logistics, and finance. With a slowing Moore’s Law constraining conventional computing, that could mean important new progress.

It’ll take years more progress before quantum computers deliver on their revolutionary progress, but delivering on promised steps toward the ultimate goal is important. Without the progress, the billions of dollars of investment could dry up and a quantum winter could chill the industry.

IBM actually announced two new Osprey systems. The first is fully tested, said Jay Gambetta, vice president of IBM’s quantum computing work.

«It works. It’s alive. All the qubits are good,» Gambetta said. «It’s another confirmation of the road map as we build larger and larger devices.»

The second incorporates improvements made to Osprey’s predecessor, Eagle, that extends the lifespan of calculations. Quantum computers today are limited by «coherence» time, which governs how long finicky qubits can maintain their state and connections to each other.

The improvements to IBM’s quantum processor design reduces electronic noise that can derail calculations, roughly doubling coherence time to 200 millionths of a second. That’s long enough for hundreds of calculation steps.

New IBM customers include telecommunications giant Vodafone, which is investigating quantum-safe cryptography, and French bank Crédit Mutuel, which is looking into financial services applications, IBM said.

IBM’s supercomputers, like those of Google and Rigetti, are called superconducting quantum computers. They rely on very cold temperatures just a fraction of a degree above absolute zero and colder than space. And they’re housed in increasingly large and expensive cylindrical refrigerators.

To get signals in and out of the quantum computers through ever-colder refrigeration zones, IBM previously used loops of gleaming cables. Now it’s got a new method, though, ribbons of communication links that are more compact.

«We solved a bottleneck in scale,» Gambetta said.

More scaling is on the horizon. For 2023, IBM plans to build 1,121-qubit Condor. After that comes 1,386-qubit Flamingo in 2024 and 4,158-qubit Kookaburra in 2025.

Correction at 8:32 a.m. PT: The story misstated the temperature at which IBM’s computer operates. It runs at a fraction of a degree above absolute zero.

Hint for today’s Strands puzzle

Today’s Strands theme is: Riding the wind.

If that doesn’t help you, here’s a clue: famed song by Christopher Cross.

Clue words to unlock in-game hints

Your goal is to find hidden words that fit the puzzle’s theme. If you’re stuck, find any words you can. Every time you find three words of four letters or more, Strands will reveal one of the theme words. These are the words I used to get those hints, but any words of four or more letters that you find will work:

DULL, TILE, TILER, SEER, GALE, GALES, HAIL, SAIL, LEEK, GLUE, HALL, TALL, HEAT

Answers for today’s Strands puzzle

These are the answers that tie into the theme. The goal of the puzzle is to find them all, including the spangram, a theme word that reaches from one side of the puzzle to the other. When you’ve got all of them (I originally thought there were always eight but learned that the number can vary), every letter on the board will be used. Here are the nonspangram answers:

HELM, HULL, KEEL, MAST, STERN, RIGGING, RUDDER, TILLER

Today’s Strands spangram

Today’s Strands spangram is SAILBOAT. To find it, start with the S that’s four letters down on the farthest row to the left, then wind across, up and down.

Google I/O 2025: How to Watch and What to Expect

With Android 16 out of the way, Google I/O will certainly be all about AI.

Google I/O 2025 takes place on May 20 and 21 with Google’s big keynote happening on day 1. We expect Big G to talk about its myriad innovations across its ever-expanding portfolio of products — almost certainly with a huge focus on AI every step of the way. If we collectively cross our fingers, promise to be good and eat all our vegetables then we may even be treated to a sneak peek at upcoming hardware.

Google also hosted a totally separate event that focused solely on Android. The Android Show: I/O Edition saw the wrappers come off Android 16, with insights into the new Material 3 Expressive interface, updates to security and a focus on Gemini and how it’ll work on a variety of other devices.

By breaking out Android news into its own virtual event, Google frees itself to spend more time during the I/O keynote to talk about Gemini, Deep Mind, Android XR and Project Astra. It’s going to be a jam-packed event, so here’s how you can watch I/O 2025 as it happens and what you can look forward to.

Google I/O: Where to watch

Google I/O proper kicks off with a keynote taking place on May 20, 10 a.m. PDT (1 p.m. EDT, 6 p.m. BST). It’ll almost certainly be available to stream online on Google’s own YouTube channel, although a holding video is yet to be available. There’s no live link on the I/O website yet, either, though you can use the handy links to add the event to your calendar of choice. Expect links to a livestream to be available closer to the day.

What to expect from Google I/O 2025

Little chat about Android 16: As Google gave Android 16 its own outing already, it’s likely that it won’t be mentioned all that much during I/O. In fact at last year’s event, Android was barely mentioned, while uses of the term «AI» went well over a hundred.

Android XR: Google didn’t talk much about Android XR during the Android show, focusing instead on the purely phone-based updates to the platform. We expected to hear more about the company’s latest foray into mixed-reality headsets in partnership with Samsung and its Project Moohan headset, so it’s possible that this is being saved for I/O proper.

Gemini: With Android being spun out into its own separate event, Google is evidently clearing the way for I/O to focus on everything else the company does. AI will continue to dominate the conversation at I/O, just as it did last year (though hopefully Google can make it more understandable) with updates to many of its AI platforms expected to be announced.

Gemini is expected to receive a variety of update announcements, including more information on its latest 2.5 Pro update which boasts various improvements to its reasoning abilities, and in particular to its helpfulness for coding applications. Expect lots of mentions of Google’s other AI-based products, too, including DeepMind, LearnLM and Project Astra. Let’s just hope Google has figured out how to make this information make any kind of sense.

Beyond AI, Google may talk about updates to its other products including GMail, Chrome and the Play Store, although whether these updates are big enough to be discussed during the keynote rather than as part of the developer-focused sessions following I/O’s opening remains to be seen.
