Quantum Computing – All Secrets Unveiled? 

The development of quantum computers has made significant progress in recent years, with steady increases in the number of qubits and advancements in the qubit stability. The primary purpose of quantum computers is to process extremely complex problems, such as molecular simulations or improved weather forecasts, which would take hundreds or thousands of years to solve using classical computers.

As many encryption algorithms also rely on very complex mathematical problems, some of these algorithms will be broken when quantum computers become powerful enough. However, there are potential mitigation measures to address this challenge.
