From Black Hole to Qubits: Evidence of Fast Scrambling in BMN theory

Understand

BMN Matrix theory admits vacua in the shape of large spherical membranes.

• Per- turbing around such vacua, the setup provides for a controlled computational frame- work for testing information evolution in Matrix black holes.
• The theory realizes excitations in the supergravity multiplet as qubits.
• These qubits are coupled to matrix degrees of freedom that describe deformations of the spherical shape of the membrane.
