Optical coherence of Er:YO ceramics for telecommunication quantum technologies
Rikuto Fukumori, Yizhong Huang, Jun Yang +2
We report an optical homogeneous linewidth of 580 20 Hz of Er:YO ceramics at millikelvin temperatures, narrowest so far in rare-earth doped ceramics. We show s…
Nanophotonic quantum storage at telecommunications wavelength
Ioana Craiciu, Mi Lei, Jake Rochman +6
Quantum memories for light are important components for future long distance quantum networks. We present on-chip quantum storage of telecommunications band light at the single pho…
Characterization of for photonic quantum technologies
Jonathan M. Kindem, John G. Bartholomew, Philip J. T. Woodburn +5
Rare-earth ions in crystals are a proven solid-state platform for quantum technologies in the ensemble regime and attractive for new opportunities at the single ion level. Among th…
Optically addressing single rare-earth ions in a nanophotonic cavity
Tian Zhong, Jonathan M. Kindem, John G. Bartholomew +8
We demonstrate optical probing of spectrally resolved single Nd rare-earth ions in yttrium orthovanadate. The ions are coupled to a photonic crystal resonator and show strong enhan…
Controlling rare-earth ions in a nanophotonic resonator using the ac Stark shift
John G. Bartholomew, Tian Zhong, Jonathan M. Kindem +5
On-chip nanophotonic cavities will advance quantum information science and measurement because they enable efficient interaction between photons and long-lived solid-state spins, s…
