Built a minimalist quantum circuit simulator in the browser — sharing the journey

Hey everyone,

I’ve been working on a small side project called AutomationGlance.

It started out as something completely different (a blog → experiments → automation ideas), but over time I kept gravitating back to one thing — building tools that help me understand complex systems better.

So I ended up building a simple quantum circuit visualiser & simulator in the browser.

What it does:

- Lets you design circuits using a minimal DSL

- Simulates quantum behaviour with shot-based execution

- Visualises probabilities, counts, and Bloch spheres

- Runs mostly client-side for instant feedback

The goal wasn’t to build a “full-featured quantum platform”, but something:

- simple

- fast

- approachable

Most quantum tools feel heavy or academic. I wanted something that feels more like “playground + intuition builder”.

Why I built this:

I realised I learn better by building small, focused tools rather than reading theory. This project became a way to explore quantum concepts hands-on without getting lost in complexity.

What I learned:

- Simplicity is much harder than adding features

- Visual feedback makes abstract concepts easier to grasp

- Building something “useful for yourself” keeps motivation high

Where I’m unsure:

Right now this sits somewhere between:

- a learning tool

- an experimental project

- a potential foundation for something bigger

Not sure what direction makes sense next.

Curious to hear from the community!
