Vzorčenje Gaussovih bozonov je model fotonskega kvantnega računalništva, ki je pritegnil pozornost kot platforma za gradnjo kvantnih naprav, ki so sposobne opravljati naloge, ki so za klasične naprave nedosegljive. Zato obstaja veliko zanimanje z vidika teorije računalniške kompleksnosti za utrjevanje matematičnih temeljev za trdoto simulacije teh naprav. Pokažemo, da v skladu s standardnimi domnevami o antikoncentraciji in trajnem Gaussovem sistemu ni učinkovitega klasičnega algoritma za vzorčenje iz idealnih porazdelitev vzorčenja Gaussovih bozonov (tudi približno), razen če se polinomska hierarhija zruši. Dokaz trdote velja v režimu, kjer se število načinov kvadratno spreminja s številom fotonov, kar je nastavitev, za katero se je na splošno verjelo, da trdota drži, vendar kljub temu ni bilo dokončnega dokaza.
Bistvenega pomena za dokaz je nova metoda za programiranje naprave za vzorčenje Gaussovih bozonov, tako da so izhodne verjetnosti sorazmerne s permanenti podmatrik poljubne matrike. Ta tehnika je posplošitev Scattershot BosonSampling, ki jo imenujemo BipartiteGBS. Napredujemo tudi proti cilju dokazovanja trdote v režimu, kjer je manj kot kvadratno več modusov kot fotonov (tj. režim visokih trkov), tako da pokažemo, da zmožnost približevanja permanentov matrik s ponavljajočimi se vrsticami/stolpci daje sposobnost za aproksimacijo permanentov matrik brez ponovitev. Zmanjšanje zadostuje za dokaz, da je GBS trd v režimu stalnega trka.
