Proof of the hiding conjecture for Gaussian boson sampling with an arbitrary number of squeezed input modes

arXiv:2608.19314v1 Announce Type: new Abstract: Gaussian boson sampling (GBS) is a sampling task proposed to demonstrate quantum advantage. We consider Gaussian boson sampling on $M$ optical modes, with $K$ equally squeezed input modes and $N$ observed photon counts. We complete the proof of the hi
