Physics [AP High School Physics] Science Fair Project

My physics teacher just sprung a science fair on us, and I need to sort out what I’m doing soon. My field of expertise is quantum physics, but I’m struggling to find projects that fit the criteria I need: 1. It needs to be a thorough, unique, and challenging project 2. I need to be able to do a lot of additional research on it (I will be writing a paper afterwards) 3. It needs to be related to quantum physics (preferably light, but anything works)

I do have a big budget for this as my birthday is coming up, and I have weeks to test and build my experiment. I just need ideas quick because my outline is due soon (yes, this was just assigned I’m not procrastinating this!)

Thank you to all who share ideas, you are much appreciated!

(NOTE: The best option I have found so far is a cloud chamber, but it doesn’t seem like something I can do a whole lot of research on)

How about something with polarisation? Maybe something about 3D-Imaging, quantum-eraser, bell-inequality or something of that effect.

I remember in Physics III(the QM-course I took) our prof presented a quantum-RNG, which was super interesting. Basically made from a beamsplitter and then detecting the path the photons took to generate a (random) number from that. We also had something about cryptography via the BB84 protocol, but I dont remember if thats viable as a personal project.
