Rolls-Royce, Xanadu, and Riverlane have reported a substantial reduction in the time required to simulate jet engine airflow by applying quantum computing methods.<\/p>\n

The collaboration combined Xanadu\u2019s PennyLane software with Riverlane\u2019s quantum algorithms, enabling Rolls-Royce to decrease simulation runtimes from several weeks to less than an hour.<\/p>\n

This outcome is expected to affect prototyping and design processes in the aerospace sector.<\/p>\n

The project is said to address the computational demands of simulating airflow in jet engines, a process that involves solving large systems of linear equations. This typically results in extended runtimes when using classical supercomputers.<\/p>\n

Xanadu CEO and founder Christian Weedbrook said: \u201cOur efforts here successfully reduced prototyping runtimes by up to 1000-fold in some instances, overcoming the unsustainable wait times of weeks for Rolls-Royce.<\/p>\n

\u201cTo make quantum simulations, and more generally quantum computing, practical for Rolls-Royce, we targeted their specific application and used our Catalyst compiler to optimise their PennyLane programmes.\u201d<\/p>\n

Quantum computing offers an alternative approach, with the potential to accelerate these simulations and support more efficient engineering workflows.<\/p>\n

Joint funding from the governments of Canada and the UK supported the initiative, which aimed to advance quantum computing expertise across both countries.<\/p>\n

Rolls-Royce provided the industrial use case, Riverlane contributed quantum algorithms, and Xanadu optimised the quantum-classical programme through its PennyLane platform and Catalyst compiler.<\/p>\n

\u00a0Rolls-Royce computational science fellow Leigh Lapworth said: \u201cThis has been a hugely successful collaboration, which has significantly advanced our quantum applications capability.<\/p>\n

\u201cThe single-minded focus on fault tolerant quantum algorithms has put us and our partners in a leading position as we enter the error-corrected era.\u201d<\/p>\n

The collaboration drew on the technical capabilities of all three organisations to address the full prototyping process.<\/p>\n

The work has produced quantum algorithm components and software implementations that will allow Rolls-Royce to access relevant insights as soon as Xanadu\u2019s fault-tolerant quantum hardware becomes available.<\/p>\n

The project also identified and addressed key bottlenecks in the simulation workflow.<\/p>\n

Riverlane staff quantum scientist Christoph S\u00fcnderhauf said: \u201cTo solve problems on a quantum computer, certain parameters of the quantum circuit need to be precomputed classically.<\/p>\n

\u201cThis process was traditionally very time-consuming. However, our research, along with that of academic groups, has significantly accelerated this step, enabling the classical preprocessing to keep pace with the quantum computation itself.\u201d<\/p>\n
