This study confirms that ytterbium ions can maintain metastable quantum states for over 30 seconds, a breakthrough that directly enhances qubit coherence times essential for scalable quantum computing. By validating decades-old theoretical predictions through precise ion-trap measurements, the research provides critical data for optimizing atomic clocks and error-correction protocols in future hardware.

Ytterbium Ions Remain Stable for 30+ Seconds, Boosting Quantum Tech

Quantum ZeitgeistJuly 26, 20263 min read

Researchers from the Universities of Amsterdam and New South Wales have discovered that ytterbium ions (Yb⁺) can remain in certain states for surprisingly long times, with evidence for a state with a lifetime of more than 30 seconds, as well as 1 second and 10 seconds. These long-lived metastable states may find applications in quantum computers and atomic clocks.

Researchers at the UvA-Institute of Physics have discovered that ytterbium ions (Yb⁺) can remain in stable, “metastable” states for over 30 seconds, a duration previously unexplored. The team, led by Rene Gerritsma, achieved this by laser-exciting Yb⁺ ions held in an ion trap and carefully observing their decay…
