A Satellite That Shoots Light Could Make China Unhackable

In the digital age, cyberattacks and global electronic surveillance can be nightmares for governments.
But China launched a satellite into orbit Tuesday that it hopes will make its communications hack-proof. And it aims to do this by using quantum technology, and a system that is, in theory, impossible to crack.
To simplify, a quantum is the smallest possible amount of many types of energy, like light. And light is exactly what's being used in this case.
