macQsimal is a 3-year project worth 10,2 Mio EURO funding under the EU Horizon 2020 Quantum Technologies Flagship. PI5's Trace Gas Sensing team joins researchers from across Europe in the endeavor to design, develop, miniaturise and integrate advanced quantum-enabled sensors with outstanding sensitivity, to measure physical observables in five key areas: magnetic fields, time, rotation, electro-magnetic radiation and gas concentration.
