In space, light travels at a speed of 299,792 kilometers per second, but scientists from the Chinese Academy of Sciences have developed a new type of material that can slow down the speed of light while losing no more energy than when it travels at full speed.
China is not the only country that has already tried to conduct similar research, as physicists from the University of Glasgow proved a few years ago that under certain conditions the speed of light can be slowed. Chinese Scientists A new way to slow down light without losing energy has been invented, which could be useful in optical communications and computing.
The new method is called electromagnetic induced transparency (EIT), where gases in a vacuum become transparent, causing the laser light to slow down and lose its energy. Therefore, a new material was created. The two-dimensional surface consists of silicon layers, thanks to which, according to the measurements The speed of light has become more than 10,000 times slower In this system. In addition to all this, the power loss was reduced to a fifth. This discovery will greatly help quantum computers in the future, and even broadband Internet.
