**Quantum computing is important and in business**

Most revenue in quantum computing lies in cloud-based quantum service businesses from IBM, Google, Microsoft, Alibaba, Amazon and others. This long-established position, for many readers, may have obscured the new reality: Quantum computing is actually here in the real world nowadays, albeit on a small scale. If you’d like to find out more about real world quantum computing, you can register for GlobalData’s free-to-attend Quantum Computing webinar on 21st April 2021 at 4pm (BST). One source is Canadian QC company D-Wave, which has been selling quasi-quantum computers since 2011 for $20m each, notably to US national labs. The quantum superposition is usually described using “complex numbers”, mathematics based on the so-called “imaginary unit”, the square root of minus one. The last few years have seen some road tests of quantum power, literally: a reduction of car waiting times by 20% in a large-scale traffic simulation, for example. These computers are based on the quantum annealing method, meaning they are suited to solving optimisation problems, but incapable of handling more advanced algorithms and problems.
