In holographic CFTs, the Bures information metric of locally excited reduced density matrices vanishes outside the entanglement wedge and matches the AdS time-slice metric inside, giving a CFT-side derivation of wedge geometry.
The surface Γ A in the bulk AdS is given by the semi circle (x−L/2)2 +η2 =L2/4

Entanglement Wedges from Information Metric in Conformal Field Theories
In holographic CFTs, the Bures information metric of locally excited reduced density matrices vanishes outside the entanglement wedge and matches the AdS time-slice metric inside, giving a CFT-side derivation of wedge geometry.
