Quantum computing could put a stop to traffic jams

But this is the 21st century! you say. Can’t AI fix these problems by optimizing traffic flow? The answer is a little more complicated: Consider that as you double the number of roads and intersections that you and thousands of other drivers are navigating, you’ll need to square the amount of time to crunch the numbers. Even the fastest supercomputers on Earth can’t currently calculate an optimal route in a human lifetime.

That’s where quantum computers might have an advantage.
