Can someone give some pointers to how homomorphic encryption is achieved? I know what it is from a high level, but would love to learn more details. What types of operation it support, what kind of encryption is used, etc. Thanks!

This is one detailed survey: https://eprint.iacr.org/2021/1402.pdf

The underlying cryptosystems are often LWE (Learning with Errors), RLWE (Ring Learning with Errors) and one called (R)GSW (named after the authors of this paper: https://eprint.iacr.org/2013/340) which is also based on (R)LWE.
