Phys. Rev. Lett. 96, 061302 (2006) [4 pages]Almost Certain Escape from Black Holes in Final State Projection ModelsReceived 27 June 2004; published 14 February 2006 Recent models of the black-hole final state suggest that quantum information can escape from a black hole by a process akin to teleportation. These models rely on a controversial process called final-state projection. This Letter discusses the self-consistency of the final-state projection hypothesis and investigates escape from black holes for arbitrary final states and for generic interactions between matter and Hawking radiation. Quantum information escapes with fidelity ≈(8/3π)2: only half a bit of quantum information is lost on average, independent of the number of bits that escape from the hole. © 2006 The American Physical Society URL:
