Researchers from the University of Amsterdam and the University of New South Wales have successfully measured long-lived quantum states in ytterbium ions, resolving a decades-old scientific question about whether these nearly stable states exist and their duration. The study demonstrates that ytterbium ions can indeed enter these metastable states, which persist for extended periods. This research provides fundamental data about the quantum properties of ytterbium that were previously unknown or unconfirmed.


The discovery of these long-lived quantum states in ytterbium ions could enable improvements in quantum computing architectures and the precision of atomic clocks. These applications depend on stable, long-lasting quantum states for reliable operation and enhanced performance.


Researchers from the University of Amsterdam and the University of New South Wales have answered a question that has been around for decades: whether ions of the metal ytterbium can enter certain long-lived, nearly stable states and, if so, for how long. The measured long-lived states may find applications in quantum computers and atomic clocks.
