• By replacing single atoms with an entangled pair of ions, physicists in Germany have demonstrated unprecedented stability in an optical clock. • Publishing their results in Physical Review Letters, a team led by Kai Dietze at the German National Metrology Institute, hope their approach could help usher in a new generation of optical clocks-opening up new possibilities in precision experiments and metrology.
Article Summaries:
- German researchers have shown that using an entangled pair of ions instead of a single atom can dramatically improve the stability of an optical clock. The team, led by Kai Dietze at the German National Metrology Institute, reported the results in Physical Review Letters. Their experiment achieved unprecedented precision, suggesting that entanglement can be harnessed to create a new generation of optical clocks. Such clocks could enhance precision experiments and advance metrology, potentially impacting time‑keeping standards and fundamental physics tests.
