I present an update on the work of the Quantum Sensing for the Hidden Sector collaboration, who are designing and building detectors for wave-like dark matter, particularly axions in the first instance, in the UK.

The toolkit of quantum technologies developed in atomic, molecular and optical physics are ideally suited to enhance the search for dark matter axions with masses above ~40 µeV. I will present an overview of a new experimental effort at Imperial College, developing technologies to initially target an axion mass range 120-250 µeV. We will use a large mode area Fabry-Perot cavity to efficiently...

Several independent observations suggest that there is more mass in the Universe than has been directly observed. Dark matter is a hypothetical new form of matter that does not interact with the electromagnetic field and has a very weak interaction with ordinary baryonic matter. WIMPs (weakly interacting massive particles) are a dark matter candidate currently widely investigated in...

The BREAD Collaboration proposes a novel dish antenna programme for broadband searches of terahertz axion dark matter. Its hallmark is a cylindrical metal barrel converting axions to photons that are focused by a parabolic reflector onto ultralow-noise quantum sensors. We present the BREAD conceptual design and science program from dark photon pilot planned at Fermilab to large-scale...

I introduce the Atom Interferometer Observatory and Network (AION), an experimental programme which aims to use cold strontium atoms to search for ultra-light dark matter and to explore gravitational waves. I outline the experimental concept of AION, and its place within the landscape of ultra-light dark matter detectors. Finally, I give progress update for the AION project in the UK, which is...

Levitated optomechanics provides a novel platform to test fundamental physics. One such application provides a unique directional dark matter direct detection technique to explore alternative parameter space to that being investigated by large scale experiments deployed underground. We detail our experiment, capable of resolving collisions in all three dimensions, utilising nanoparticles...
