Using quantum computers for traffic flow optimisation

14 March 2017

The Volkswagen Group is the world’s first automaker to use quantum computers, further expanding its digital competence for the future.

In this context, Volkswagen Group IT is cooperating successfully with leading quantum computing company D-Wave Systems on a research project for traffic flow optimisation. In the course of this project, IT experts from the Volkswagen labs in San Francisco and Munich have been the first to develop a smart mobility program on the D-Wave quantum computer. Quantum computers can solve highly complex problems many times faster than conventional supercomputers. To date, quantum computing technology has been used primarily by scientific institutes, government agencies, and in the aerospace sector.

At CeBIT 2017 in Hannover, Volkswagen and D-Wave will be announcing its strategic cooperation and, as a world premiere, demonstrating a software program that optimises traffic flow on a quantum computer. In the course of this project, experts from the Volkswagen Code Lab in San Francisco and the Volkswagen Data Lab in Munich and used data from approximately 10,000 taxis in Beijing.

Dr.Martin Hofmann, CIO of the Volkswagen Group, says: “We are doing digital pioneering work. Quantum computing technology can bring tremendous progress to Volkswagen with respect to all the key IT topics of the future. We are now laying the foundation for the future by learning to make effective use of the strengths of a quantum computer. Our cooperation with D-Wave is a milestone on the way to the digital future of our Group. This shows that there is no other company where IT is now as exciting as at Volkswagen.”

Robert “Bo” Ewald, President of D-Wave International, says: “The goal of our cooperation with Volkswagen is to apply our quantum computing technology to Volkswagen’s real-world computing challenges and make a positive impact on their business. Bringing together our quantum computing experts with their automotive AI experts is the perfect model to make significant progress toward that goal. This project is a great example of how computing in the future will be done, with talented people looking at new ways to solve old problems, and combining traditional computers with quantum computers to deliver an improved solution.”

The strategic cooperation between the two companies focuses on the joint use of quantum computing systems. Experts from the Volkswagen Group IT labs are testing the programming of applications and algorithms on D-Wave’s quantum computer. This will result in the development of specialist expertise at Volkswagen and on the identification of meaningful applications that would benefit from the application of quantum computing within the Group.

The first research project is traffic flow optimisation in the Chinese mega-metropolis of Beijing. Data scientists and AI specialists from Volkswagen have successfully programmed an algorithm to optimise the travel time of all public taxis in the city. The computing principle of a quantum computer is especially well-suited for this project because it natively solves optimisation problems.

In simplified terms, an optimisation problem considers how a specific resource (such as time, money or energy) can be used in the best possible way in a certain scenario. The complexity of the task and therefore the computing capacity required grow exponentially with the number of factors to be considered, taking conventional digital computers to their limits.

The Volkswagen Group is the first automaker to work intensively with quantum computing technology. Group IT expects a wide range of application possibilities especially in the areas of autonomous driving, the robotic enterprise (AI-supported process control), the smart factory, machine learning and intelligent mobility solutions.

Further projects with D-Wave are to follow. Initially, the main focus is on the acquisition of specialist knowledge. The IT experts are testing applications and algorithms to make the best possible use of the tremendous computing potential of D-Wave‘s quantum computer. In addition, the Volkswagen Group plans to intensify cooperation with universities and scientific institutes in the field of quantum computing.
