Things are moving so fast in the quantum computer field that it's hard to gauge what is the current state of the art. The news that Microsoft has been making major advances in the field, for example, is more about the practicality of writing software for and providing production grade hardware components for what is at its core still very much an experimental technology. On the other hand, the recent news that Russian researchers have broken the 50 qubit threshold is of major significance to security professionals particularly. As a result, this article is an attempt to shed some light on the current state of the art in quantum computing and to give some background and context so that someone with limited technical knowledge can understand the main issues. Questions I’ll try and answer include: What is quantum computing in simple terms? Why can’t everybody build there own quantum computer? Why is it particularly powerful in breaking encryption? What is the sig...
