I am working on a project for our local science fair and decided on researching quantum computers. (This is what my focus will be in college.) Though, I expect to work on this far past the time allotted for that. I would like to build a superconductor based qubit using Josephson Junctions. The main goal is to be able to measure electron spin of an atom and won’t be capable of programing. This seemed somewhat plausible as I have a mentor at our local university as well as lab access, a liquid helium dewer and most of the supplies. The problem arose when I mentioned material deposition to create the junction as we would not have access to that. So my question is: What other options are there for doing this? His focus is in material physics and so he has the most experience with super conductors and hence my research has been too. Would a photonic system be more plausible to test? Also for the fair, any ideas on a simpler experiment that could be created and tested with the 2 month time limit relating to the subject? Thanks in advance!
