The Download: Quantum computing for health, and why the world doesn’t recycle more nuclear waste

This is today’s edition of The Download, our weekday newsletter that provides a daily dose of what’s going on in the world of technology.

A $5 million prize awaits proof that quantum computers can solve health care problems 

In a laboratory on the outskirts of Oxford, a quantum computer built from atoms and light awaits its moment. The device is small but powerful—and also very valuable. Infleqtion, the company that owns it, is hoping its abilities will win $5 million at a competition next week. 

The prize will go to the quantum computer that can solve real health care problems that conventional “classical” computers are unable to solve. But there can be only one big winner—if there is a winner at all. Read the full story.

Why the world doesn’t recycle more nuclear waste 

There’s still a lot of usable uranium in spent nuclear fuel when it’s pulled out of reactors. Recycling could reduce both the waste and the need to mine new material, but the process is costly, complicated, and not fully efficient.

One More Thing 

PSIQUANTUM

Useful quantum computing is inevitable—and increasingly imminent 

Last year, Nvidia CEO Jensen Huang jolted the stock market by saying that practical quantum computing is still 15 to 30 years away. He also suggested that those computers would need Nvidia GPUs to function. But Huang’s predictions miss the mark—both on the timeline and the role his company’s technology will play.  

Quantum computing is rapidly converging on utility. And that’s good news, because the hope is that they will be able to perform calculations that no amount of AI or classical computation could ever achieve. Read the full story.
