Nuclear Spins in a Solid Exceeding 10-Hour Coherence Times for Ultra-Long-Term Quantum Storage

Demonstrates nuclear spin coherence times exceeding 10 hours in ${}^{151}{\mathrm{Eu}}^{3+}:{\mathrm{Y}}_2\mathrm{Si}{\mathrm{O}}_5$ using ZEFOZ and dynamical decoupling, extending the known rare-earth coherence frontier beyond the prior six-hour record.
