Abstract[English]
Methods are provided for configuring a boson sampler, the boson sampler comprising a light source, a reconfigurable interferometer having one or more configurable elements, and one or more photodetectors. The method comprises determining a partial derivative of an expected value of an observable with respect to a parameter of a configurable element of the boson sampler. The method further comprises configuring a configurable element of the boson sampler based on the determined partial derivative.[French]
L'invention concerne des procédés de configuration d'un échantillonneur de bosons, l'échantillonneur de bosons comprenant une source de lumière, un interféromètre reconfigurable ayant un ou plusieurs éléments configurables, et un ou plusieurs photodétecteurs. Le procédé consiste à déterminer une dérivée partielle d'une valeur attendue d'un observable par rapport à un paramètre d'un élément configurable de l'échantillonneur de bosons. Le procédé consiste en outre à configurer un élément configurable de l'échantillonneur de bosons sur la base de la dérivée partielle déterminée.
