  The correspondence between quantum mechanics and noncommutative geometry is
illustrated in the context of the noncommutative ${\rm AdS}^2_{\theta}/{\rm
CFT_1}$ duality where ${\rm CFT}_1$ is identified as conformal quantum
mechanics. This model is conjectured to describe the gauge/gravity
correspondence in one dimension. Applications to quantum black holes and
emergent geometry/gravity are also discussed.
