Development of a Scalable Quantum Memory Platform -- Materials Science of Erbium-Doped TiO${}_2$ Thin Films on Silicon

Manish Kumar Singh, Gary Wolfowicz, Jianguo Wen +6

Rare-earth ions (REI) have emerged as an attractive candidate for solid-state qubits, particularly as a quantum memory. Their 4f-4f transitions are shielded by filled 5s and 5p orb…
