On étudie l’opération de complexification libre pour les groupes quantiques compacts, G→G c . On montre qu’avec des définitions convenables, cette opération induit une bijection entre groupes quantiques orthogonaux libres de niveau infini, et groupes quantiques unitaires libres satisfaisant G=G c .

We study the free complexification operation for compact quantum groups, G→G c . We prove that, with suitable definitions, this induces a one-to-one correspondence between free orthogonal quantum groups of infinite level, and free unitary quantum groups satisfying G=G c .
