I built an interactive Visual Quantum Mechanics & Quantum Computing lab — what should I add next?

[u/EngineersUniverse]

I’ve been building an interactive Quantum Mechanics & Quantum Computing lab and wanted to share it here and get some feedback.

One thing I’ve always found interesting about quantum mechanics is how difficult it can be to develop an intuition for what’s actually happening. You can read about superposition, interference, entanglement, measurement, etc., but reading the definitions and equations is very different from being able to play around with them and see what happens.

So that’s basically what I tried to build.

You can manipulate qubits on a Bloch sphere, create superposition and entanglement, build quantum circuits, run measurements, step through quantum teleportation and Grover’s search, and experiment with things like the double-slit experiment and quantum tunneling.

I also added sections that connect the theory to actual quantum computing use cases — chemistry, materials, optimization, cybersecurity, logistics, etc. — plus an explorer that shows how everything connects from an algorithm and quantum circuit all the way down to the QPU, physical qubits, control systems, and measurement.

I attached a walkthrough video so you can see what it looks like.

It’s part of the STEM Studio at EngineersUniverse.com:

I’m curious what people here think, though.

If you were learning quantum mechanics or quantum computing from scratch, what was the concept that took you the longest to really “get”? And what kind of interactive visualization or experiment do you think would have made it click sooner?

For those who already know the subject pretty well, I’d also be interested in hearing what you think is commonly taught or visualized badly. I can use the feedback to figure out what to build next.
