Dans cette Note nous développons la technique des espaces fractionnaires dans le cadre d'espaces d'opérateurs locaux. Le résultat principal est une variante du théorème non commutatif d'Albrecht–Vasilescu sur les extensions, lequel implique une solution du problème du moment quantifié.

In this Note we develop the fractional space technique in the local operator space framework. As the main result we present the noncommutative Albrecht–Vasilescu extension theorem, which in turn solves the quantized moment problem.
