Black-Hole Radiation Decoding is Quantum Cryptography. (arXiv:2211.05491v1 [quant-ph])

We propose to study equivalence relations between phenomena in high-energy
physics and the existence of standard cryptographic primitives, and show the
first example where such an equivalence holds. A small number of prior works
showed that high-energy phenomena can be explained by cryptographic hardness.
Examples include using the existence of one-way functions to explain the
hardness of decoding black-hole Hawking radiation (Harlow and Hayden 2013,
Aaronson 2016), and using pseudorandom quantum states to explain the hardness
of computing AdS/CFT dictionary …
