A drag-and-drop quantum circuit simulator that runs in your browser. A toy for exploring and understanding small quantum circuits.
It's kinda silly having to make custom gates for this. Just have a gate that does nothing and has an editable text string.

I have read about optimisation technics, when we have really big numbers of gates. I've read about 3D visualisation that leads to us e common steps which we should follow...

As you can see [in this gif](https://i.stack.imgur.com/qceK3.gif), the descriptions of the parameterized gates on the right half are too small and not really visible. This looks like a bug. Could...
