Polarisation and Temperature Dependence of Er${}^{3+}$:CaWO${}_4$ -- Towards a Solid-State Rare-Earth Ion-Doped Quantum Memory

Mikhael T. Sayat, Trevor R. Lee, Suchit Negi +6

In the endeavour of developing quantum memories, Er${}^{3+}$:CaWO${}_4$ has emerged as a promising rare-earth ion-doped (REID) crystal platform due to its long optical coherence times…
