How quantum technology is helping Toyota assemble cars

On October 21, 2022, Japanese auto giant Toyota and Fujitsu Limited announced cooperation as part of a project to introduce Fujitsu Digital Annealer technology at car manufacturing facilities.

Digital Annealer is a quantum digital model-based architecture capable of real-time parallel optimization calculations with speed, accuracy, and scale that are unattainable for standard computers. The solution is based on key elements of quantum computing: superposition, quantum tunneling and entanglement. This provides a simultaneous assessment of a huge number of potential options and lightning-fast conclusions. In addition, Digital Annealer gives a huge gain in energy consumption compared to existing full-fledged quantum computers.

Complex large-scale problems of combinatorial optimization can be solved in a matter of seconds. This means that problems that were previously impossible to solve using ordinary computers or that had to be processed by choosing combinations can now be solved in almost real time, notes Fujitsu.

In the case of the automotive industry, Digital Annealer technology is designed to improve logistics and vehicle design operations, as well as to optimize the operation of robotic equipment. In addition, the efficiency of placing parts available at the enterprise can be improved.

At the first stage, Toyota introduced the Digital Annealer system at the Tsutsumi plant, and in the future plans to expand it to other enterprises in Japan and abroad. It is assumed that the technology will help in adapting production lines to constantly changing market conditions, as well as help reduce the burden on employees.^[1]
