Xanadu and Rolls-Royce to build quantum computing tools with PennyLane

Xanadu and Rolls-Royce will work together to accelerate research in aerospace by co-developing new features in PennyLane

TORONTO, Jan. 17, 2023 /CNW/ - Xanadu, the world leader in photonic quantum computing, and Rolls-Royce are co-developing new quantum algorithm tooling for PennyLane, Xanadu's open-source quantum computing software widely used for quantum machine learning, chemistry, and optimization.

Xanadu and Rolls-Royce are committed to advancing the field of quantum computing, studying its potential to solve complex problems and building tools with lasting business impact. The first project will develop quantum software functionality tailored for Quantum Singular Value Transformation, or QSVT, in PennyLane to help Rolls-Royce accelerate its research into quantum algorithms for aerospace applications. QSVT is a modern paradigm for quantum algorithms that enables innovative methods for employing quantum computers to explore a variety of problems of interest.

Rolls-Royce, a leader in aerospace and defence, is actively involved in long-term quantum computing research aimed at developing robust algorithms and applications that are ready for the fault-tolerant quantum computers expected over the next decade. Quantum computing is a potentially disruptive technology for the aerospace industry with a wide range of applications from materials chemistry to product design using computational fluid dynamics (CFD).  Rolls-Royce is committed to achieving net-zero carbon emissions by 2050 and has recently successfully tested a hydrogen powered gas turbine in collaboration with EasyJet. Quantum computers, which aim to drastically out-perform classical ones, are expected to play a key role in meeting aerospace's climate goals.

"We are proud to partner with Rolls-Royce on this project," said Dr. Juan Miguel Arrazola, Head of Algorithms at Xanadu. "Rolls-Royce is a world-class engineering company with deep expertise in complex simulations; their support will be invaluable in guiding our design and implementation for PennyLane, which we hope will help accelerate research into improving quantum algorithms."

"We are excited to be working with Xanadu on our quantum computing journey," said Dr. Leigh Lapworth, Rolls-Royce Fellow and Quantum Computing Lead. "They have demonstrated rapid advancements in scaling up photonic quantum computers and have built an impressive software library in PennyLane. The focus on QSVT is a natural fit for us as it extends our research beyond CFD and I look forward to running our first case on a Xanadu computer."
