Google has announced that it aims to build a "useful, error-corrected quantum computer" within the decade, which it hopes could be used to tackle big problems relating climate change and advance scientific progress.

As part of the announcement, yesterday the company unveiled its new Quantum AI campus in Santa Barbara. It will be home to the company's first quantum data center, its quantum hardware research laboratories, and quantum processor chip fabrication facilities. The push comes about 18 months after Google first claimed to have demonstrated quantum supremacy — performing a task that can't be matched by the most powerful computers we have today.

"We are at this inflection point," Hartmut Neven, the scientist leading Google's Quantum AI program, told The Wall Street Journal. "We now have the important components in hand that make us confident. We know how to execute the road map."

Trump allies are questioning US democracy. Tech is letting them.

U.S. election infrastructure is exceedingly secure, and voter fraud here is so rare it’s comparable to your annual chances of getting struck by lightning. Despite this, former President Donald Trump and a long list of allies in the Republican Party have spent the last two years questioning the overall integrity of the U.S. election system. Many of those allies are now candidates themselves, and their coordinated attack on the country’s status as a democracy is not a relic of 2020. Some have already started repeating these “Big Lie” charges ahead of next week’s midterms. And the social platforms that help them spread their message have prepared few measures to stop it.
