    "body_text": "The result covers Fock-state boson sampling, fixed-squeezing Gaussian boson sampling and fermion sampling with magic inputs, at inverse-polynomial total-variation error and with high probability over Haar-random interferometers. Under a weaker flatness assumption, the authors obtain quasipolynomial simulation without Haar randomness and polynomial simulation at logarithmic depth with constant loss per layer. These are asymptotic theoretical conditions, not a demonstration that every noisy quantum experiment is classically easy.",
