It is commonly accepted that states in a conformal field theory correspond to classical spacetimes with Anti-de-Sitter asymptotics.In this essay, we argue that such states should be coherent in the large-N limit, and show implications in the spacetime emergence mechanism. In particular, we argue that the microstates that compose a black hole (entangled) state inthe Van Raamsdonk description cannot be interpreted as classical geometric configurations. Therefore, the conclusion is that care should be taken to interpret (micro)states in the gravity side, and that quantum coherence plays an important role in the description of the holographic emergence phenomenon.
