Entanglement is probably the most puzzling phenomenon observed in quantum systems. A research team @unibas.ch & @lkblab.bsky.social has now shown how entanglement of spatially separated quantum objects can be used to measure several physical parameters simultaneously with greater precision.

Congratulations to physicist Christophe Salomon who has just won a 2025 #BalzanPrize!

This award is related to his work on atoms and ultra-precise measurement of time.

He will receive c.€800K, half of which must then be invested in research.
