The black hole information puzzle can be resolved if two conditions are met.Firstly, if the information of what falls inside a black hole remains encodedin degrees of freedom that persist after the black hole completely evaporates.These degrees of freedom should be capable of purifying the information.Secondly, if these purifying degrees of freedom do not significantly contributeto the system's energy, as the macroscopic mass of the initial black hole hasbeen radiated away as Hawking radiation to infinity. The presence ofmicroscopic degrees of freedom at the Planck scale provides a natural mechanismfor achieving these two conditions without running into the problem of thelarge pair-creation probabilities of standard remnant scenarios. In the contextof Hawking radiation, the first condition implies that correlations between the{\em in} and {\em out} Hawking partner particles need to be transferred tocorrelations between the {\em microscopic degrees of freedom} and the {\em out}partners in the radiation. This transfer occurs dynamically when the {\em in}partners reach the singularity inside the black hole, entering the UV regime ofquantum gravity where the interaction with the microscopic degrees of freedombecomes strong. The second condition suggests that the conventional notion ofthe vacuum's uniqueness in quantum field theory should fail when consideringthe full quantum gravity degrees of freedom. In this paper, we demonstrate bothkey aspects of this mechanism using a solvable toy model of a quantum blackhole inspired by loop quantum gravity.
