sensors capable of measuring movement with unseen precision tagged posts

1. The atomic part of the hybrid experiment. The atoms are contained in a micro-cell inside the magnetic shield seen in the middle. Photo: Ola J. Joensen 2. The optomechanical part of the hybrid experiment. The cryostat seen in the middle houses the vibrating membrane whose quantum motion is measured. Photo: Ola J. Joensen 3, If laser light used to measure motion of a vibrating membrane (left) is first transmitted through an atom cloud (center) the measurement sensitivity can be better than standard quantum limits envisioned by Bohr and Heisenberg.
