Summary

When atoms absorb photons with specific energy, they can make transitions to different quantum states. Atomic spins, at the same time, behave like tiny magnets – making an atom the smallest multi-tool possible. macQsimal’s scientists are using vapour cells filled with trillions of atoms, and by combining MEMS technology with laser beams, they develop atomic quantum sensors. Researchers aim to use quantum-enhanced sensors to measure magnetic fields, time, rotation, electromagnetic radiation, and gas concentration with unprecedented sensitivity.
