(Why) does the late radiation after page time entangle with the early radiation?
In Jerusalem lectures by Harlow Pg. 53 it is said that
At the beginning of the
evaporation process the radiation that comes out is entangled with the remaining black
hole. But eventually it must ...

How to derive the probability distribution of reduced density matrix eigenvalues for randomly chosen pure states in Page's theorem?
Motivation
I am trying to reproduce the proof in Page's theorem as conjectured in the seminal paper Average Entropy of a Subsystem by Don N. Page. It is crucial in various resolutions of black hole ...

Is there any way you can compute a scattering amplitude using quantum information? [closed]
Are there any applications of quantum information theory in particle physics? I hear a it a lot in talks (e.g Erik Verlinde). For example is there any way you can compute a scattering amplitude using ...

Is HaPPY code a certain type of MERA?
Pastawski, Yoshida, Harlow, and Preskill introduced the HaPPY code in their (now famous) paper, arXiv:1503.06237, as a way to model the AdS/CFT correspondence as a quantum error-correcting code. ...

Correlation function late time decay and information loss
In the perturbative treatment of, let's say, a scalar field theory on AdS spacetime, the correlation functions decay exponentially at late times, indicating, as people say, information loss.
I guess ...

Holographic dualities and strong subbadditivity of entanglement entropy
Recent analysis of inequalities satisfied by entanglement entropy in AdS bulk duals have led to establishing an equivalence between Strong Subadditivity and the Null Energy Condition (NEC)
How hard ...

Black holes in AdS/CFT
In Swingle's work Entanglement Renormalization and Holography, he mentioned that a black hole in AdS bulk corresponds to a finite temperature boundary state. With the MERA picture of the entanglement ...

Implication of non-positive tripartite information
Hayden et al 2011 showed that tripartite information is non-positive given Ryu-Takanayagi formula. (For definition of tripartite information, see for instance section 4.4 of this paper)
Is there ...

Entangled event horizons
Assuming it is possible in principle to entangle the degrees of freedom of the event horizons of two black holes, and that this is something that can be done, either after the black hole is formed, or ...
