Never-Repeating Patterns of Tiles Can Safeguard Quantum Information

This extreme fragility might make quantum computing sound hopeless. But in 1995, the applied mathematician Peter Shor discovered a clever way to store quantum information. His encoding had two key properties. First, it could tolerate errors that only affected individual qubits. Second, it came with a procedure for correcting errors as they occurred, preventing them … Read more

A Celebrated Cryptography-Breaking Algorithm Just Got an Upgrade

This is a job for LLL: Give it (or its brethren) a basis of a multidimensional lattice, and it’ll spit out a better one. This process is known as lattice basis reduction. What does this all have to do with cryptography? It turns out that the task of breaking a cryptographic system can, in some … Read more

The future of computing and entertainment

It’s night. I’m at a lake near Oregon’s Mount Hood, sitting on the beach. Jazz music is playing as I write. I’m not in the real world. Well, I sort of am.  I’m wearing Apple’s new Vision Pro headset, which looks like a fancy pair of glowing ski goggles. Apple’s long-awaited headset, which starts at … Read more

Apple’s Vision Pro Headset Shows the Future of Computing Is Bulky and Weird

I spent a little more than 30 minutes wearing the Apple Vision Pro today, and I saw the future of computing. The impressive technology in Apple’s upcoming mixed-reality headset lays the groundwork for what’s to come, but I am at a crossroads. I’m not sold on the bulky headset. Apple announced the Vision Pro at … Read more

ChatGPT’s Hunger for Energy Could Trigger a GPU Revolution

The cost of making further progress in artificial intelligence is becoming as startling as a hallucination by ChatGPT. Demand for the graphics chips known as GPUs needed for large-scale AI training has driven prices of the crucial components through the roof. OpenAI has said that training the algorithm that now powers ChatGPT cost the firm … Read more

The One Part of Apple Vision Pro That Apple Doesn’t Want You to See

Joanna Stern of The Wall Street Journal. Courtesy of Joanna Stern If Vision Pro is mostly meant to be used from a couch cushion or desk chair, the external battery pack may not factor in as much. As I pointed out last spring, it’s an unusual choice for a consumer tech company that has, over … Read more

I demoed Xreal’s AR glasses for spatial computing and they’re better than I expected

June Wan/ZDNET AR glasses took off in 2023, but even a tech geek like myself, who’s initially typed the news portion of this article while wearing a pair during my flight to CES admits that the product category needs to be better. Because no matter which pair you buy on the market right now, they … Read more

5G and edge computing: What they are and why you should care

Tony Studio/Getty Images Picture our techscape before 2005 and then our technology environment today. We are living in a totally mobile-first world that relies on the fact that nearly everyone has a smartphone. Entire industries have changed, been enabled, and been disrupted, all because of the smartphone. Each mobile G generation has changed our world. … Read more

The Holy Grail of Quantum Computing Is Finally Here. Or Is It?

Andersen and Lensky of Google disagree. They do not think the experiment demonstrates a topological qubit, because the object cannot reliably manipulate information to achieve practical quantum computing. “It is repeatedly stated explicitly in the manuscript that error correction must be included to achieve topological protection and that this would need to be done in … Read more

Top emerging 5G and edge computing innovations to watch out for now

Sammyvision/Getty Images Edge and 5G computing have been promising transformative computing for a number of years, but it’s only lately that compelling and viable use cases have been emerging, pushing these technology sets into the mainstream.  The phenomenon has been accelerating. The latest data from the Global Mobile Suppliers Association shows there are at least … Read more
