WG3: Proof-of-principle experiments

There are three major experimental platforms at the moment: photons, cold atoms for matter-wave interferometry and atomic clocks, and levitated nanoparticles/optomechanics provide different opportunities for quantum technologies in space, while the technological readiness level (TRL) is one of the main credentials in order to qualify for a space mission at all. The TRL is very different for the different experimental platforms.

It is imperative for space that each quantum technology has passed relevant proof-of-principle experimental tests on ground. Within this Action, and specifically WG3, we aim to coordinate such experimental activities to optimise and accelerate the TRL of each platform, and thus pave the way to the specific orbit requirements to perform the desired experiments in space.

This could imply joining forces to work towards the demonstration of a matter-wave interferometer for nanoparticles on Earth – a later version of which should see full fruition if operated in space. WG3 will also coordinate the sharing of knowledge with respect to available technologies and experimental techniques for performing experiments in space-relevant settings. This will allow us to answer the question “What is the best technical solution to realise the experiment in space?”

Further we will be working to identify the option of joint missions with different technological platforms on the same spacecraft. 

Ideally WG3 will entail a joint approach between scientists and engineers at universities and space industries as well as at national and international space agencies.
