2021: Announcement of a quantum computer for train control
In mid-October 2021, Japanese industrial giant Hitachi announced the development of an automation system based on quasi-quantum computing technology to optimize railway operations. According to the developers, their decision makes a staff schedule in just 30 minutes, while usually this process takes 3-5 days.
Japan lags behind the United States and China in the practical application of quantum technologies. Hitachi's move to use this technology in the transport sector could accelerate its implementation across the country. Hitachi uses a patented quasi-quantum computer for calculations. Initially, the company developed a crew planning system based on a single railway line, taking into account factors such as breaks and weekends after night shifts. During a practical experiment with a railway company serving 440 trains per day, the company chose the optimal distribution of labor from 10 million combinations. The described task is considered difficult for automation using ordinary computers, but the new system took only half an hour to solve it.
In addition to optimizing the work of staff, the system reduces the number of employees needed to manage trains by 15%. Hitachi hopes to market the system in mid-2022. The technology will be available not only in Japan, but also abroad. The company is also developing a system for optimizing the distribution of rolling stock, which distinguishes between serviceable cars and cars requiring maintenance.
The key technical advantage of this technology will be the ability to automatically control the configuration of trains and the interval for 24 hours without stops in order to optimize operating costs and energy costs, while maintaining a high level of reliability and diagnosability. Due to the fact that on October 18, 2021 there is a great need for modern trains capable of supporting these functions in management.[1]
