What is a Quantum Computer in Layman Terms.

I have wondered if anyone could explain quantum computers in more common terminology. Well this video comes fairly close. Try it and let me know.

Thanks and please comment below. What would you do if you had one?

I watched this video and then ran the tutorials on the IBM quantum computers. That was a lot of fun. I learned enough to make a "superdense information transfer" example work (this is outside the tutorial).

An example:

below is an example of a quantum circuit that makes a three-qubit GHZ state
| ⟩=(|000⟩+|111⟩)/2⎯⎯√.
- A Hadamard gate on qubit 0, which puts it into the
superposition state (|0⟩+|1⟩)/2⎯⎯√(|0⟩+|1⟩)/2.
- A controlled-Not operation ( CX) between qubit 0 and qubit .
- A controlled-Not operation between qubit 0 and qubit 2.
On an ideal quantum computer, the state produced by running
this circuit would be the GHZ state above.
