Please tell me how conservation of energy and mass apply in QM. I want to confirm something I read somewhere about QM not conserving energy.

How about you tell us what you read, and then we can confirm whether that specific statement is valid?

As long as the Hamiltonian is symmetric under time translation then energy is conserved.

Before the experts step in and cry out "not again" :) here is a link to a thread two days ago...

What a shame that no-one refered to my reference in Baez's site where it talks about non-conservation of energy in virtual particles.
