A Finnish optical clock set a new accuracy record, bringing us closer to a new definition of the second! 🙌
⏱️ At the end of last year, our team at VTT MIKES set a new record in optical clock frequency measurements using a strontium single‑ion clock with exceptionally low uncertainty and high uptime.
➡️ Precise timekeeping enables reliable internet, navigation, secure transactions and scientific breakthroughs, and the need for accuracy continues to grow as society becomes more digital.
➡️ This milestone helped position Finland at the forefront of efforts to update the definition of the second, expected within the next decade.
