The attractor mechanism as a distillation procedure

Understand

In a recent paper it has been shown that for double extremal static spherically symmetric BPS black hole solutions in the STU model the well-known process of moduli stabilization at the horizon can be recast in a form of a distillation procedure of a three-qubit entangled state of GHZ-type.

• By studying the full flow in moduli space in this paper we investigate this distillation procedure in more detail.
• We introduce a three-qubit state with amplitudes depending on the conserved charges the warp factor, and the moduli.
• We show that for the recently discovered non-BPS solutions it is possible to see how the distillation procedure unfolds itself as we approach the horizon.
