英文摘要
Rare-earth ions in crystals are useful in precision measurements and quantum information science because of their exceptional optical and spin coherence properties. We show that the nuclear spin coherence time of $^{153}\mathrm{Eu}^{3+}$ ions doped into yttrium orthosilicate can be significantly enhanced by driving the $^{89}\mathrm{Y}$ nuclear spins in the host crystal. This improvement in spin coherence time opens up ways to improve the precision of measurements using rare-earth-doped crystals.
