Disclaimer: This response to the question is not an answer, but although I would prefer to put it in the comment box, it's too large. It is my hope that it leads to an answer from the references cited.
Also, I feel the excerpt that occupies the bulk of this answer may genuinely be of help to the OP.
From Quantum Error Correction
Abstract: Over the last few years it has become increasingly clear that there is a deep connection between fundamental physics and quantum information. The connection goes back to the remarkable discovery that black holes carry entropy with an amount given by the horizon area. I will present new evidence that this is only the tip of the iceberg, and prove that a similar area law applies to more general Renyi entanglement entropies. To demonstrate the simplicity of my prescription, I will use it to calculate for the first time the mutual Renyi information between two disks in a holographic conformal field theory (CFT) of arbitrary dimension. I will briefly comment on the prospect of verifying this area law experimentally in light of recent advances in measuring Renyi entropies. Furthermore, I will provide quantum corrections to the area law and use it to solve a long-standing problem in quantum gravity: what region of the dual spacetime is described by a subregion in a holographic CFT?
The answer to this question lies in a new perspective that I will advocate: holography is a quantum error correction code. [My Emphasis]
I hope you get a real answer, but I feel if you follow on from the highlighted statement above, it may be of some use.
Other, more newbie friendly sources (I mean myself here) include pdfs, such as Holographic quantum error-correcting codes: Toy models for the bulk/boundary correspondence and Is spacetime a quantum error-correcting code? Pastawski, Yoshida, Harlow, Preskill = HaPPY arXiv:1503.06237 which has lots of pictures (always good) and may be easier to follow.
My apologies: a Google search will be needed to find these, as my tablets has issues with copying pdf URLs.
