Black hole/quantum machine learning correspondence

Abstract:We explore a possible connection between the black hole information paradox and interpolation geometry underlying the double descent phenomenon in quantum machine learning. State-dependent operator reconstruction on the Hawking radiation can be formulated as a quantum linear inverse problem defined on the black hole-radiation purification. In this picture, the Page time corresponds to the interpolation threshold, where the dimensions of the remaining black hole and the radiation become comparable. Using the Marchenko-Pastur law, we study the spectrum of the corresponding Gram matrices and obtain the variance of the linear reconstruction coefficients. The Page point is then related to both a change in the rank structure of the two subsystems and a strong enhancement of the coefficient variance near the interpolation threshold. This suggests a possible relation between the Page transition and interpolation phenomena in quantum machine learning.
