- <p><br>We present a theoretical and device-oriented analysis of a hybrid quantum memory platform<br>combining integrated nanophotonic waveguides with rare-earth-ion-doped crystals operating at 4 K.<br>The architecture bridges two regimes: (i) solid-state long-lived spin coherence in Eu3+ :Y2 SiO5 and<br>Pr3+ :Y2 SiO5 , and (ii) scalable photonic routing in SiN and TFLN integrated circuits.<br>We derive performance bounds for evanescent coupling, multimode storage capacity, and end-<br>to-end efficiency under experimentally realistic constraints. Our results indicate that such hybrid<br>systems can operate as compact quantum repeater nodes with ∼ 102 –103 temporal modes, while<br>maintaining ms-scale spin coherence and chip-scale footprint.<br>Beyond theoretical modeling, we discuss implementation constraints and design trade-offs relevant<br>to near-term nanophotonic fabrication platforms.</p>
