Computers help us every day. We use them for photos and messages. To keep these safe, computers use secret codes. These codes use random numbers. But computers are not always good at this. Sometimes they use patterns. If there is a pattern, other people can guess your password. This is not safe. Now, scientists in Switzerland have a new idea. They use quantum science. This is the study of very small things. In this small world, things happen by chance. There are no patterns. The scientists used these small things to make a perfect random number. It is very hard to guess. This new way will make computers safer. It will protect our private information. No one can steal our photos now. We can trust our computers and our secrets more. Do you use a strong password for your computer? It is important to stay safe online!
