Volkswagen progressing with work on quantum computing, develops traffic management system for taxi companies

The Volkswagen Group is progressing with its work with quantum computers (earlier post). For the first time, Volkswagen researchers have succeeded in using a quantum computer to develop a traffic management system that will replace forecasting for urban traffic volumes, transport demand and travel times with precise calculations.

As a result, public transportation organizations, taxi companies, and transport service providers will be able to deploy their fleets considerably more efficiently while minimizing waiting times for passengers. Volkswagen and its quantum computing partner D-Wave are presenting the project at the WebSummit technology conference in Lisbon.

Quantum computers can solve highly complex tasks such as traffic optimization much faster than conventional supercomputers. In some cases, a solution is only possible using quantum computers. Volkswagen sees considerable potential in using this cutting-edge computing technology for building new applications and business models within the company.

Volkswagen is forging ahead with practically-oriented research on quantum computers and is gaining essential specialist knowledge. We want to gain an in-depth understanding of applications of this technology which could be beneficial to the company, including traffic optimization. Public transport organizations and taxi companies in large cities are highly interested in managing their fleets efficiently. Our quantum-optimized traffic management system could help make that a reality.

The next era of quantum computing is application development, and D-Wave has been focused on enabling practical quantum application development since day one. Volkswagen’s innovative work using D-Wave quantum computers to pursue applications in traffic optimization is an example of the real-world impact quantum computing can have on both business operations and people’s everyday lives.

To develop the new traffic management system, Volkswagen experts first analyze anonymized movement data (from smartphones or transmitters in vehicles) with conventional computers to calculate traffic accumulation and the number of people involved. The second step, optimization, is completed with a quantum algorithm. For example, it’s possible to assign precise numbers of vehicles to different destinations (“demand spots”) on a predictive basis to provide transportation for all waiting passengers.

This would eliminate such costly transportation inefficiencies as taxis and buses driving considerable distances without passengers, long passenger wait times, or a shortage of vehicles in high-demand locations. Public transportation operators could add additional trips to fixed timetables to better align with demand. For Volkswagen, this quantum-optimized traffic management system could be offered as a new commercial service. Volkswagen experts also see application possibilities for their algorithm in traffic infrastructure and vehicle networking, especially as it relates to autonomous vehicles.

The Volkswagen experts first want to test the algorithm in Barcelona as they have an adequate database for this city. They are cooperating with the telecommunications service provider Orange and the data science specialist Teralytics. As a general principle, the algorithm could be scaled up or down for any city.

Volkswagen and quantum computing. Highly specialized IT experts from Volkswagen, including data scientists, computer linguists and software engineers, are working together at the IT labs in San Francisco and Munich to develop the potential of quantum computers for applications which will be beneficial for the company.

The main focus is on the programming of algorithms on quantum computers. These are subject to different laws than in the case of conventional computers. In the field of quantum computing, the Volkswagen Group is cooperating with technology partners D-Wave and Google, who provide the Volkswagen experts with access to their systems.

D-Wave Leap Quantum Application Environment. In October, D-Wave Systems announced the immediate availability of free, real-time access to the D‑Wave Leap Quantum Application Environment (QAE). Leap is the first cloud-based QAE providing real-time access to a live quantum computer. In addition to access, Leap provides open-source development tools, interactive demos and coding examples, educational resources, and knowledge base articles.

Leap builds on D-Wave’s continuing work to drive real-world quantum application development. To‑date, D‑Wave customers have developed 100 early applications for problems spanning airline scheduling, election modeling, quantum chemistry simulation, automotive design, preventative healthcare, logistics, and more. Many have also developed software tools that make it easier to develop new applications.
