Les magnétomètres à base de SQUID (Superconducting QUantum Interference Device) sont sensibles à de très faibles variations de flux magnétique et sont ainsi utilisés pour lʼétude dʼeffets quantiques à lʼéchelle macroscopique. Nous avons réalisé une mesure linéaire du déplacement dʼun microrésonateur mécanique enchâssé dans la boucle supraconductrice dʼun dc SQUID. En utilisant un fort champ magnétique et un amplificateur fonctionnant en régime cryogénique, cette méthode de mesure nous a permis dʼatteindre une résolution qui nʼest que 4,4 fois la limite quantique.

Superconducting quantum interference devices (SQUIDs) can detect tiny amounts of magnetic flux and are also used to study macroscopic quantum effects. We employ a dc SQUID as a linear detector of the displacement of an embedded micromechanical resonator with a femtometer sensitivity. We discuss the measurement method, including operation in high magnetic field and a cryogenic amplification scheme which allows us to reach a resolution which is only a factor 4.4 above the standard quantum limit.
