The Download: Amazon’s quantum chip, and preventing battery fires

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.

Amazon’s first quantum computing chip makes its debut

The news: Amazon Web Services has announced Ocelot, its first-generation quantum computing chip. While the chip has only rudimentary computing capability, the company says it is a proof-of-principle demonstration—a step on the path to creating a larger machine that can deliver on the industry’s promised killer applications, such as fast and accurate simulations of new battery materials.

Why it matters: Like any computer, quantum computers make mistakes. Without correction, these errors add up, with the result that current machines cannot accurately execute the long algorithms required for useful applications. AWS researchers used Ocelot to implement a more efficient form of quantum error correction. Read the full story.

The best time to stop a battery fire? Before it starts.

Flames erupted last Tuesday amid the burned wreckage of the battery storage facility at Moss Landing Power Plant. It happened after a major fire there burned for days and then went quiet for weeks.

The reignition is yet another reminder of how difficult fires in lithium-ion batteries can be to deal with. They burn hotter than other fires—and even when it looks as if the danger has passed, they can reignite.

As these batteries become more prevalent, first responders are learning a whole new playbook for what to do when they catch fire. Casey Crownhart, our senior climate reporter, dug into it.

The big story

How Bitcoin mining devastated this New York town

April 2022

If you had taken a gamble in 2017 and purchased Bitcoin, today you might be a millionaire many times over. But while the industry has provided windfalls for some, local communities have paid a high price, as people started scouring the world for cheap sources of energy to run large Bitcoin-mining farms.

It didn’t take long for a subsidiary of the popular Bitcoin mining firm Coinmint to lease a Family Dollar store in Plattsburgh, a city in New York state offering cheap power. Soon, the company was regularly drawing enough power for about 4,000 homes. And while other miners were quick to follow, the problems had already taken root. Read the full story.
