How quantum computing can change cybersecurity

Quantum computing still sounds like the realm of science fiction. The promise is that quantum computing can compute more than a hundred million times faster than the fastest supercomputer today. This will have extremely positive implications for solving big problems in science.

However, it has a darker side effect: encryption that would take thousands of years to crack with conventional computers could be removed in minutes, or even seconds. The consequence is that adversaries are now able to collect and store data that they can attack with a quantum computer for years to come. Some commercial and personal data will remain sensitive in the long term. Therefore, it is worth securing your data for the future to withstand quantum attacks.
