I can prove to you that there is literally nothing a physically possible quantum computer can do that a regular computer can't. It's a pretty common proof in any quantum computing class and isn't even particularly long.
Quantum programming exists now, and it can be simulated on traditional computers. It's also one of those things that really only has limited real world applications. There are some interesting algorithms that can be solved by quantum hardware that would just take a lot longer on traditional hardware.
The list of quantum algorithms isn't that long and while there are some major speed increases from application of quantum hardware, the systems are still bound by traditional computational rules.

It's up to you. If you ever took a linear algebra class (even if you failed it) it should be understandable.
