This looks interesting, but I have no idea what I'm supposed to do with it. Could you explain what the controls and the inputs are and what are we supposed to try to achieve with it. Thanks!

By the way, I'm not familiar with Qbits, and so that may be why I'm confused.

So let me explain:
Your computer probably isn't a quantum one, it uses bits, whitch can be either 0 or 1. Q bits on the other hand, can be 0, 1 or in a superposition in whitch they are both 0 and 1 at the same time.
So thats what I did, green Qbit is 1, red is 0, and yellow is superposition.

JP - I understand what a quantum computer is (just the very basics). Actually the correct spelling of a data bit is Qubit (I checked with Google).

The thing that I don't understand (and you provide no instructions) is how to use your scene. In other words, how do I input data? What should I expect to see after inputting data? This is a "sandbox" which implies that it allows a user to play around with it. But without instructions, I have no idea where to begin!

Alright I updated it and added instructions.

Sorry, but those are not instructions how to use it. You only explained what a Qubit is and the fact that machines can be assembled, but you don't explain HOW to assemble a machine. You need to explain it this way (as an example): 1. Click on the red button which will cause (whatever) to happen. 2. Input your data in the gray text box. The data can be in a range of -256 to +256 (or whatever).

Get it now? That's how you explain to a newbie how to use something that they have never used before. Assume they know NOTHING about the scene. If you can't understand what I'm telling you, then I give up!

Ok now it has instructions

Is there anything useful I can make with this?
