EPQ ideas for physics/computer science

I'm in year 12 and I've just started looking at ideas for my EPQ in the field of physics, I'm taking maths, further maths, physics and chemistry but I'm also interested in computer science.
Originally I was interested in Quantum computing but that's quite vague and I'm not sure what a specific question would be.
Otherwise I was thinking of doing something on emergence
but I'm not sure how to structure either of those. I'm still open to switching topics completely as long as it is physics/computer science relevant and I'd be really grateful if anyone has any ideas or advice on which path I should take?
Thank you

In the exact same position as you. I'm taking the same A levels as you. My Sixth Form are doing a physics Christmas project which can be turned into an EPQ. We are just doing making things that interest us, for example, I'm making a cricket bowling machine and documenting the process and I have peers making ping pong ball guns and electric skateboards. My advise is to just have fun with it. I find with more STEM based EPQs it's easier to craft something as it is hard to find original topics to explore as it has mostly been done. I recommend making a list of ideas discussing it with your teacher and choosing based on what's most creative, fun but also practical.

Thanks, I'll speak to my teacher. Also could I ask if you're you doing any other super curricular activities as well as the EPQ and what sort of course you'd like to do at uni because I'm still conflicted and it's interesting to see what other people are doing
