Classical computers have been the backbone of our digital age, powering everything from scientific research to business operations. However, they do have their limitations. To understand it better, let's start with an example.

Suppose you are a truck driver and you have to deliver products in 25 different regions throughout the United States.

Now, if you want to know the best route to complete your task, do you know how much time a classical computer will take to give you the output? It will take more than 20,000,000 (20 Million) years. That is crazy, right?

Using the fastest computers during this calculation could reduce some time. But still, classical computers struggle a lot to solve certain problems like dealing with large datasets and large numbers of possible combinations.

Other types of problems that classical computers struggle to solve:

And that is where quantum computers come in.
