Ultra-narrow homogeneous linewidths of erbium-doped silica glass fibers at millikelvin temperatures: magnetic field and temperature dependence
Farhad Rasekh, Nasser Gohari Kamel, Mahdi Bornadel +4
Erbium-doped solids are promising candidates for fiber-based quantum networks due to their emission wavelength, which aligns with the telecom band over which optical fibers exhibit…

Hole burning experiments and modeling in erbium-doped silica glass fibers down to millikelvin temperatures: evidence for ultra-long population storage
Mahdi Bornadel, Sara Shafiei Alavijeh, Farhad Rasekh +5
We use spectral hole burning to investigate spin dynamics within the electronic Zeeman sublevels of the ground state of the erbium ions in erbium-doped fibers (EDF). Conducted at u…

Unwanted couplings can induce amplification in quantum memories despite negligible apparent noise
Faezeh Kimiaee Asadi, Janish Kumar, Jiawei Ji +2
Theoretical quantum memory design often involves selectively focusing on certain energy levels to mimic an ideal -configuration, a common approach that may unintentionally overl…
