Does anyone have experience with anchoring a gun safe to a post tensioned concrete slab?

Best bet would be to talk to a builder or structural engineer.
I would treat it as an ordinary concrete slab. This is not the same thing pre-tensioned concrete.
If you are not a Structural Engineer, I would not give such advice. (If you are a Structural Engineer, you would already know better...)
To the OP: Your post-tensioned slab is still a prestressed element, and cutting prestressing tendons could potentially lead to a catastrophic failure. DO NOT BLINDLY DRILL INTO THE SLAB.
If you are the property owner, hire a Structural Engineer, licensed in the state where the building is located, and ask his advice. If the building's as-built drawings are available, it may be possible to evaluate the floor without the need for extensive testing. A Pacometer test may be needed to locate reinforcement within the slab.
If you are a tenant in the building, forget it. The odds of convincing the owner to hire a Structural Engineer to determine whether/where you can drill for anchors are not in your favor.
I would use something like this.

The HDI-P anchor allows for a shallow embedment of 3/4", meeting the embedment depth requirements for post-tension concrete.
