China Launches World’s First Quantum Communications Satellite

hackingbear quotes a report from The Verge: China’s quantum network could soon span two continents, thanks to a satellite launched earlier today. Launched at 1:40pm ET, the Quantum Science Satellite is designed to distribute quantum-encrypted keys between relay stations in China and Europe. When working as planned, the result could enable unprecedented levels of security between parties on different continents. China’s new satellite would put that same fiber-based quantum communication system to work over the air, utilizing high-speed coherent lasers to connect with base stations on two different continents. The experimental satellite’s payload also includes controllers and emitters related to quantum entanglement. The satellite will be the first device of its kind if the quantum equipment works as planned. According to the Wall Street Journal, the project was first proposed to the European Space Agency in 2001 but was unable to gain funding.
