In the last article (check here), we met a strange situation: running an experiment was easier than simulating it. Boson sampling gave us a glimpse of how quantum systems can overwhelm even our biggest classical supercomputers.

Now let’s take that idea one step further (please read the last episode, if you haven’t already - here).

Suppose you build a quantum computer. How do you actually test it?

How do you verify that the results it gives you are correct…
when no classical computer can tell you what the right answer should be?

Welcome to the weird world of quantum benchmarking.
