The reason for this is that even the most powerful computers available have trouble calculating the energy produced by a jet engine and how that energy lifts an airplane. This shows that quantum computing technology will take an important and inevitable place in the aviation industry. Rolls Royce uses Nvidia's A-100 model GPUs in these simulation quantum computers. Despite their name, these devices do not qualify as quantum computers in the full sense of hardware. They're rather "quantum computer" prototypes with fewer quantum bits than real quantum computers. This prevents us from fully relying on the precision of the calculations made. However, we can say that the algorithm used by Rolls Royce is quantum based. The company's HHL-based algorithm has the potential to speed up computational flow dynamics (CFD) simulations, but we don't yet have a quantum computer that can run these algorithms at full capacity. That's why initial testing and collaborations with Nvidia are vital to understanding and improving this technology.
