Cybersecurity researchers and analysts are rightly worried that a new type of computer, based on quantum physics rather than more standard electronics, could break most modern cryptography. The effect would be to render communications…
Self-driving cars are coming. Tech giants such as Uber and Alphabet have bet on it, as have old-school car manufacturers such as Ford and General Motors.
Imagine American politics for a moment as a laboratory experiment. A foreign adversary (let's call it "Russia") begins to play with the subjects, using carrots and sticks to condition their behavior.
In a chilly warehouse just outside of Boston, the brute toils away. It's 600 pounds of orange and black metal and whirring motors, a massive robotic arm that picks up car parts and places them on a table.
Personal technology was so awful this year that nobody would think you were paranoid if you dug a hole and buried your computer, phone and smart speaker under six feet of earth.
In 2013 I moved from Paris to Beijing to study China's financial system. I stayed for two years and became fluent enough to translate economics books from Mandarin into English and give talks on monetary policy in Mandarin.
Last Wednesday, a day after Google's C.E.O., Sundar Pichai, sat before the House Judiciary Committee to answer questions about the company's search engine, Donald Trump's 2020 campaign manager, Brad Parscale, wrote a post on …
On September 29, 2017, a Chinese satellite known as Micius made possible an unhackable videoconference between Vienna and Beijing, two cities half a world apart. As it whisked across the night sky at 18,000 miles (29,000 kilometers)…
With Microsoft's decision to end development of its own Web rendering engine and switch to Chromium, control over the Web has functionally been ceded to Google. That's a worrying turn of events, given the company's past behavior…
The contrast could hardly be more striking. In October, Vice President Mike Pence delivered a blistering speech accusing China of stealing prized US technology and military hardware. Barely two weeks later, one of Beijing's most…
Will 2019 be the year when quantum computers show they have the right stuff? Google says so; one of the company's labs, in Santa Barbara, California, has promised that its state-of-the-art quantum chip will be the first to perform…
The concept of time travel has always captured the imagination of physicists and laypersons alike. But is it really possible? Of course it is.
The growing use of work robots and the deployment of artificial intelligence have been most disruptive in just those areas of the country that provided President Trump with crucial margins of support in 2016.
When a massive earthquake and tsunami hit the eastern coast of Japan on March 11, 2011, the Fukushima Daiichi Nuclear Power Plant failed, leaking radioactive material into the atmosphere and water.
Imagine, if you will (and you should), a big American tech executive being detained over unspecified charges while on a trip to Beijing.
If you only scan the headlines, you could be forgiven for thinking that the U.S.-China trade war is mainly about tariffs.
A quantum computer capable of breaking the strongest codes protecting online communications and computer data is highly unlikely to appear within the next decade, a new report says. But leading experts still recommend the U.S…
Without artificial intelligence there wouldn't be much left of Facebook as we know it today.
In the fall of 1965, President Lyndon Johnson's administration announced a plan to consolidate hundreds of federal databases into one centralized National Data Bank.
