I was wondering where to look for open Ph.D. positions for specific sub-fields/topics of quantum computing like error correction, optimization, quantum chemistry, etc. It is preferable if the offers/positions can be sorted subfield-wise or topic-wise.
You may keep a tab on the Jobs page or in particular the Ph.D. positions page on Quantiki. You can view the extended descriptions for each position by clicking on the individual position names and see the project details like location, duration of the Ph.D., potential supervisors, etc. The positions are not restricted to any specific country as such and cannot be sorted according to sub-fields (as far as I know).
