Schematic depiction of the ψ-ontic and δ-continuous ψ-epistemic models.
Λ is the space of ontic states λ. (a) ψ-ontic models: distinct quantum states never overlap with each other. (b) ψ-epistemic models: different quantum states may result in the same ontic state λ; δ-continuous ψ-epistemic models: all states in the ball of radius δ share at least one ontic state λ, such as ψ1, ψ2, ψ3 and ψ3, ψ4, ψ5.
