Initialization protocol for efficient quantum memories using resolved hyperfine structure

We describe a quantum memory spectral preparation strategy that optimizes memory efficiency and bandwidth in materials such as 167 Er 3+ :Y 2 SiO 5 in a high-field regime, where the hyperfine structure is resolved. We demonstrate the method in 167 Er 3+ :Y 2 SiO 5 by preparing spectrally isolated 18... View More
