Een consortium van VU en UvA onderzoekers gaat quantumtechnologie inzetten om met ongekend hoge precisie te meten aan atomen en moleculen waarvoor zeer nauwkeurige theoretische voorspellingen beschikbaar zijn, om daarmee zowel de bekende als mogelijke hogere natuurwetten veel nauwkeuriger in kaart te brengen.", "summary_en": "The known laws of physics such as quantum mechanics and Einstein’s theory of relativity have proven to be\n\nvery successful.

A consortium\n\nof researchers of VU and UvA will deploy quantum technology for extremely precise investigations of single\n\natoms and molecules, for which very accurate theoretical predictions exist.
