Understanding the quantum computing threat

The threat posed by quantum computing is worth a separate section, given the efforts made by the IT industry to implement and commercialize a fully functioning quantum computing architecture in the near future.

In the research sector, quantum computing has, in fact, turned into a realistic opportunity; also in light of Google's recent announcement claiming that they have reached quantum supremacy, that is to say, they have managed to perform a calculation on their quantum computing platform that is not feasible with traditional computers.

In order to consciously assess whether quantum computing constitutes a real threat to the blockchain, and in general, for all those architectures that base their ...
