Comparing the performance of practical two-qubit gates for individual Yb ions in yttrium orthovanadate
Mahsa Karimi, Faezeh Kimiaee Asadi, Stephen C. Wein +1
In this paper, we investigate three schemes for implementing Controlled-Z (CZ) gates between individual ytterbium (Yb) rare-earth ions doped into yttrium orthovanadate (YVO or…
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…
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…
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 over…
