Description: Generation of spin-squeezed atomic ensembles to reduce quantum projection noise in atom-interferometric gravitational-wave/dark-matter detectors.
Hobson co-leads the Ultracold Strontium Laboratory within the AION atom-interferometer collaboration, developing squeezed strontium atomic ensembles and quantum-non-demolition measurement techniques to beat the standard quantum limit in long-baseline atom-interferometric searches for dark matter and gravitational waves, alongside a parallel programme on ultra-precise, shock-resistant optical clocks. Actively recruiting postdocs as the group builds out its cold-atom laboratories.
Kasevich is a pioneer of light-pulse atom interferometry, building cold-atom sensors of rotation, acceleration, and gravity that rival or exceed classical inertial instruments, and precision tests of general relativity and searches for dark matter and gravitational waves via large-scale atom interferometers (including MAGIS-100). His 2022 Nature paper demonstrated distributed quantum sensing with mode-entangled, spin-squeezed atomic states, extending entanglement-enhanced metrology to networks of separated sensors.
