A team of scientists was able to "split" an atom into its two possible spin states, up and down, and measure the difference between them even after the atom resumed th... | <urn:uuid:94ab953a-bccc-4e20-8cdf-0d17891b3388> | CC-MAIN-2020-24 | https://www.foxnews.com/science/franken-physics-atoms-split-in-two-put-back-together | s3://commoncrawl/crawl-data/CC-MAIN-2020-24/segments/1590347394756.31/warc/CC-MAIN-20200527141855-20200527171855-00379.warc.gz | en | 0.9589 | 1,173 | 4.15625 | 4 |
The next generation of computers is a few years off, but it’s pretty damn cool.
It’s like no computer you’ve ever seen, nor are you likely to ever own. It promises speed and the ability to tackle problems ordinary computers can’t handle.
The machine is the D-Wave 2X, and the only working model outside the company is in... | <urn:uuid:5e97a1c0-d40f-4698-ac66-8e57c561f9e2> | CC-MAIN-2020-24 | https://www.massarate.ma/google-and-nasa-team-up-on-quantum-computer.html | s3://commoncrawl/crawl-data/CC-MAIN-2020-24/segments/1590347404857.23/warc/CC-MAIN-20200529121120-20200529151120-00581.warc.gz | en | 0.928975 | 1,184 | 3.75 | 4 |
The six stages of quantum networks
Quantum networks will go through different stages of development until they reach their full functionality.

An accurate analog clock ticks along with a constant precision and well known frequency: one tick per second. The longer you let it tick, the better to test its accuracy—10 times as long corresponds to a ten-fold improvement in any frequency uncertainty.
But is there a faster way to determine a frequency?
