We analyze the results of the test of π/2 qubit rotations on a public quantum computer provided by IBM. We measure a single qubit rotated by π/2 about a random axis, and we accumulate vast statistics of the results. The test performed on different devices shows systematic deviations from the theoretical predictions, which appear at level 10–3. Some...
La bioéconomie questionne les méthodes d'évaluation des performances des filières. Les méthodes traditionnelles très liées à l'économie industrielle restent polarisées par des indicateurs macro-économiques ou d'intégration intersectorielle. Elles rendent peu compte des coûts cachés ou externalités sociales et environnementales. Dans différents cont...
Access to the groundwater economy has frequently enabled an economic boom but is also believed to increase inequalities between farmers. The present study analyses social changes in a rural community as it entered and evolved in a groundwater economy, and today increasingly has to cope with groundwater depletion. The case study was conducted in the...
This paper analyses the central role of water infrastructure in the transformation of hydrosocial territories through a case study in the Forquilha catchment in Brazil's Nordeste. Decentralised state-led infrastructural development reinforced the resilience of communities to drought, leading to more sustainable water access by many families; this w...
Background: Strengthening the surveillance of zoonotic diseases emergence in the wild meat value chains is a critical component of the prevention of future health crises. Community hunters could act as first-line observers in zoonotic pathogens surveillance systems in wildlife, by reporting early signs of the possible presence of a disease in the g...
En tant qu'unités linguistiques spécifiques, les néologismes formels remplissent une diversité de fonctions selon que l'on s'intéresse au français contemporain hexagonal ou à une variété de contact, où le français interagit localement avec une multiplicité de langues. Au Burkina Faso, par exemple, le français, ancienne langue officielle devenue lan...
La technique de l'insecte stérile est une alternative prometteuse pour s'affranchir des pesticides en agriculture. Cependant, malgré ses promesses, elle peine à se développer car elle implique de repenser et de construire un nouveau monde sociotechnique. Cet article étudie les différents agencements entre humains et non-humains qui caractérisent ch...
The jurisdictional approach concept emerged in response to the widespread failure of sectoral forest conservation projects. Despite its increasing popularity, understanding jurisdictional approach outcomes is challenging, given that many remain in either the formation or implementation stage. Furthermore, diverse stakeholders hold different perspec...
We, as humans, are currently facing urgent socio-ecological challenges (climate change, demographic increase, booming inequalities, etc.). These challenges are reinforced by systems of financial control at the international level, super-extractive strategies on natural resources, lack of effective democracy, surge of conflicts and wars, etc. This b...
