Terms of Service

Welcome. qu00b is a browser-based quantum circuit simulator. It’s free to use, the source is public, and we’re genuinely glad you’re here. These terms are the boring-but-necessary legal wrapper around that.

Using qu00b

Use it to learn, to experiment, to teach, to build demos. Personal, educational, and non-commercial use is wide open. If you want to do something commercial with it, the source is MIT / Apache-2.0 licensed, so you probably can — just read the license.

The one thing that will get you banned: deliberately breaking things for other users. Don’t do that.

Your saved circuits

Circuits you save belong to you. We store them on your behalf. We won’t sell them, read them for ads, or do anything weird with them. If an account has been completely inactive for a very long time (we’re talking years), we reserve the right to clean it up — but we’d rather not.

The math is real; the warranty is not

qu00b simulates quantum circuits using real linear algebra. The probabilities it outputs are mathematically correct to floating-point precision. That said, this is a learning tool, not a certified research instrument. Don’t use it as the sole basis for published results without verifying against a second source.

Changes

If we update these terms in a meaningful way, we’ll note the new date at the top. Continued use after an update means you’re cool with the new terms.
