Quantum mechanics mostly but with impacts in quantum computing. If you come from the computing side and want to tangentially back into quantum mechanics from the quantum computing side, I would highly recommend Andy Matuschak and Michael Nielsen's highly approachable intro to quantum computing which goes into surprising depth - https://quantum.country/qcvc
Once you feel like you have a good grasp, just dive into the deep end (why not?) with a pictorial survey of the geometry of quantum states - https://arxiv.org/pdf/1901.06688.pdf
Then see where the gaps are and decide if it's worth digging in deeper to understand this better :-)
