I am aware of Oxford's Quantum Foundations mailing list that regularly advertises conferences and openings for academic positions related to quantum theory. What are other mailing lists that advertise stuff like this in the area of quantum computing?
For the interested: you can subscribe to the Quantum Foundations list by sending an email to [email protected]
Also, this question seems to be related: Resources to keep a track on open Ph.D. positions in specific sub-fields/topics of quantum computing
