An error of only one hundredth of a second - and your navigator could miss by 3,000 km. To prevent this, atomic clocks are installed in satellites. Some of these clocks are so precise that over 300 thousand years they can accumulate an error of only one second. This incredible precision is achieved thanks to quantum effects. They are also used in other extremely sensitive devices - quantum sensors. They can detect single photons, help scientists study brain activity and monitor greenhouse gas levels in the atmosphere. And in the future, such technologies may allow cameras to look behind obstacles and see through fog. In the new material of GigaScience, a joint popular science project between Sberbank and RBC, we tell you how quantum sensors are designed, where they are used, and why, thanks to atomic clocks, we can precisely determine our position. GigaChat's neural network helps you understand complex scientific concepts. Advertising, PJSC Sberbank, 18+.
