About quantum sensors

Superposition states are naturally very sensitive to the environment, and can therefore be used to make very accurate sensors. As a result of steady progress in material quality and control, cost reduction and the miniaturisation of components such as lasers, these devices are now ready to be carried over into numerous commercial applications.

macQsimal will contribute to the strategic objectives of the Quantum Technologies Flagship in the sub-domain of Sensing and Metrology. The choice of atomic vapor cells makes coherent quantum processes available to applications: advanced cell-based sensors optimally exploit single-particle coherence, with the potential to harness also multi-particle quantum coherence for even greater sensitivity. Fabricating such atomic vapor cells as MEMS will allow for high-volume, high-reliability and low-cost deployment of miniaturised, integrated sensors, critical to wide-spread adoption. Through its balanced basic and applied research concept, macQsimal will also address the fundamental questions of quantum-enhancement techniques such as squeezing, entanglement and quantum non-demolition measures to form a basis for scientific breakthroughs of future research.
