Quantum Blockchain Technologies PLC (LON:QBT) recently changed its name from Clear Leisure, which was more than a cosmetic alteration. “Our investment programme is focused on selecting the most innovative and out-of-the-box start-ups in the blockchain and cryptocurrencies sector, with whom we will work alongside to develop exciting synergies,” it said. Below is an abridged transcript from a recent conversation with chairman Francesco Gardin, which provides a flavour of what is planned. After that is a brief explainer on quantum computing. Tell us more about Quantum Blockchain Technologies Let's focus on quantum [computing] first. There are few things that changed the course of mankind. Recently we witnessed the digital revolution; in the early 60s, computers were basically invented thanks to the transistor. And we are now very close to a similar revolution. [Quantum computers] could do something which are orders of magnitude superior to our digital computers. So, when you have this unlimited amount of computing power, you have no more boundaries to what you can do.
