Noisy intermediate-scale quantum era

Okay, so imagine you have a really cool machine that can solve really hard math problems that even adults struggle with. This machine is called a quantum computer.

But, as with any machine, there are errors that can happen which can mess up the answer. It's like if you were drawing a picture and your hand accidentally slipped and made a squiggly line where you didn't want it.

Now imagine lots of these errors happening in the quantum computer. It makes it harder to trust the answers that come out of the machine because they might not be accurate.

This is what we call the noisy intermediate-scale quantum era. It's when we have quantum computers that can solve harder problems than before, but the answers might not be completely accurate.

Scientists are working really hard to find ways to reduce these errors and make the answers more reliable. But for now, we have to be patient and keep studying and testing these quantum computers to make sure we can trust them.
