He prefaced this class by telling us it was the hardest physics lab offered for undergraduates. While I don't know how necessarily true this statement is, I personally found this class very, very, time consuming and difficult. What is nice is the collaborative atmosphere with fellow classmates because its so small (6 of us this quarter), so make friends quickly!

It's hard because you're learning brand new skills every week which are the utter basics of optical design (AMO, physical chemistry, imaging science) , including polarizers, waveplates, lasers, optical cavities, etc. I personally don't have an immediate gift for experimental science and struggled quite a bit as I kept learning new things. The actual quantum part is the final experiment which is an experimental verification of Bell's Inequality (an optional Hong-Ou-Mandel). That being said, this class is so cool and more importantly, immediately useful. I thought optics from lower div was god awful boring until we started looking at the more advanced EM topics that you don't typically learn from 110 series. Plus, you get a stronger intuition for how QM works!

Highly recommend but not for the faint of heart.
