How Can Quantum Computing Improve Autonomous Vehicles?
Various industries are excited by the arrival of quantum computing. How can it help with the development of self-driving cars? This is a vital question for the companies that see our car culture transformed by vehicles that understand their surroundings better—and react in more intelligent ways—than ever before.
Understanding Quantum Computing
The field of quantum computing is intricate and derives from the foundational principles of quantum mechanics. It employs quantum bits or qubits, which can inhabit multiple states at once. This ability, far beyond the binary operations of classical computers, makes quantum computing a still largely theoretical but potentially very powerful computational paradigm.
For instance, a classical computer processes data in a series of commands that must be obeyed in a certain order. A classical computer works using billions (indeed, trillions) of tiny switches that can be either off or on. By multiplying and adding in gated sequences, these switches perform operations and execute programs. In sharp contrast, a quantum computer processes data in parallel. A quantum computer works using very few (indeed, sometimes just one) switches that can be in multiple states at the same time. Here, “state” means anything we want to represent. A switch can represent 0, 1, or, using quantum physics, an infinite superposition of 0, 1, and everything in between. These parallel operations are what make quantum computers potentially gigahuge faster than classical ones.
In addition, a report by McKinsey states that quantum computing could potentially unleash annual economic value of between $1 trillion and $3 trillion across numerous industries by 2035. This figure underscores the potential heft that quantum computing could carry in the mostly undreamt-of future, with particular regard to already-named fields that process huge quantities of data and make gigantic decisions at data timescales.
How Can Quantum Computing Improve Autonomous Vehicles?
Understanding how quantum computing will affect self-driving cars involves first looking at the problems those cars face. They aren’t mainly about computing—they’re about the kind of computing required to analyze the kind of data that’s coming in and also to understand, in real time, the kind of decisions that must be made if you want to consider the thing a true vehicle. And all this to say, we rely heavily on computing to make sense of data that’s coming from all kinds of systems, including our own, which must, in devices like LiDAR, be as parallel as the systems we’re using to analyze the data. These cars must ‘decide’ using data that’s coming in at large scale and with high velocity.
Colossal aspects of autonomous vehicle functions can be augmented by quantum computing in the following ways:
- Speed of Data Processing: Computing with quanta can handle the intricate dataset tasks at a pace that leaves even the fastest supercomputers we have today in the dust. One way of illustrating this is to say that what a quantum computer can do in one second could take our best supercomputers one hundred thousand years to accomplish.
- Route optimization is necessary for efficiency in autonomous vehicles. It brings together an assortment of variables, like traffic patterns, the weather, and road conditions, and does it all in real time. Of course, that would be hard, maybe impossible, to do with classical computers if you really consider the size and shape of the problem.
- Machine Learning: Predictive models that tell us how the world works often need to be refitted to accommodate new situations. A car doesn’t drive by the same “rules” everywhere, no matter what it or we might think. If a car is to be truly autonomous, it needs to learn from its experiences in different situations everywhere it goes and at all times. And, unlike us (at least for most of us), it needs to learn fast.
In addition, businesses like Volkswagen and D-Wave Systems are already delving into quantum algorithms to enhance traffic management and optimize route choices.
Challenges and Considerations
Nonetheless, the integration of quantum computing into self-driving cars presents certain difficulties. The first is that quantum technology is in its infancy. Although companies are investing a lot of money into research, the practical and universal application of it is still years away.
In addition, there are worries about how dependable and secure quantum systems will be. Because of their extreme sensitivity to environmental changes, for example, quantum computers may turn out to be less efficient and reliable than expected. But even if we assume that the darn things work because we have a not-stupid way to cool them down and keep them contained, another problem arises: how secure is the data processed on these potentially world-changing systems? That’s a huge issue given the risks involved with something as potentially alloying to public safety as driverless cars.
Even with these obstacles, the drive toward quantum computing technology keeps growing—and funding has poured in from both the public and private sectors. Since 2018, the U.S. quantum industry has received over $1.5 billion from the government and private sector. This showcases the belief that the switch to quantum computing could revolutionize many sectors, including transportation.
Real-world Applications and Future Perspectives
Examining the potential for quantum computing to enhance autonomous vehicles requires a look at specific occurrences in the real world. Firms such as IBM are laboring mightily on solutions that will run directly to the benefit of vehicular navigation systems. With the kinds of algorithms that could be achieved using quantum systems, which do not exist yet in workable form, we could expect to see vastly improved efficiencies across the board. That goes for travel times, energy consumption, and any emissions that might result from autonomous vehicles.
Also, car makers like Ford and BMW are studying the application of quantum computing to logistics and fleet management. To this end, Ford has partnered with several quantum computing companies to explore how this technology might optimize their supply chain processes, which in turn, affects their strategies for getting autonomous vehicles on the road.
As a result, we may see a future for autonomous vehicles that uses a hybrid model, where classical computing systems work in tandem with quantum systems to offer a total, comprehensive solution. This model would let us use the strengths of both types of technology to do the real work of making autonomous vehicles safe and reliable.
The Path Forward
Ultimately, revolutionizing autonomous vehicles through quantum computing has vast prospects. How does or can this particular form of computing improve the kind of vehicle that can drive itself? For one thing, it can (and when it comes to the prospect of actual working machines, should) enhance the speed at which data are processed. For another, it can (and again, should) optimize the routes such vehicles take. And for a third thing, it can improve (and, of course, should improve) the kind of machine learning that all forms of artificial intelligence (AI) use. Nevertheless, challenges abound.
The investments, the research, and the collaboration of industries across the board are key to advancing this technology. A concerted effort by government, private sector, and academic partners is required to foster an environment conducive to innovation in the field of quantum computing.
The full potential of autonomous vehicles is fast approaching, and when it comes to defining the future of transportation, the interaction of classical and quantum systems will be a major force—especially in terms of upward mobility.
