$\mathrm {^{151}Eu^{3+}}$-doped yttrium silicate ($\mathrm {^{151}Eu^{3+}:Y_2SiO_5}$ ) crystal is a unique material that possesses hyperfine states with coherence time up to 6 h. Many efforts have been devoted the development of this as optical quantum memories based on bulk crystals, but integrable structures (such waveguides) can promote {^{151}Eu^{3+}:Y_2SiO_5}$-based practical applications, not demonstrated so far. Here we report fabrication type 2 waveguides in using femtosecond-laser...
The extraction of tungsten from scheelite was carried out using a sulfuric acid solution with oxalic as the chelating agent. Tungsten obtained in form highly soluble hydrogen aqua oxalato tungstate (H2[WO3(C2O4)·H2O]) during leaching process, while calcium remained residue sulfate dihydrate (CaSO4·2H2O). About 99.2% leached at 70 °C, 1.5 mol/L acid, 1 liquid/solid ratio 25:1 (mL/g), an to molar 1:1, stirring speed 300 r/min and time 2 h. H2[WO3(C2O4)·H2O] thermally decomposed into tungstic...

Meanwhile, the electronic band structure simulated Cambridge Serial Total Energy Package. The conclusions are as follows: order of emissivity in near‐IR is La 0.67 Sr 0.33 Al Mn O > Co LaAl . 0–2.5 μm at room temperature, can reach 0.9504....
Abstract— The objective of this study is to design a novel cone‐shaped lens cap on LEDs in order achieve high optical efficiency an ultra‐thin directly lit RGB LED backlight unit (BLU) for large‐sized LCD TVs. use the could play role diffuser, low light‐efficiency component BLU, gain higher and simultaneously provide satisfactory uniformity light distribution. coated with aluminum outside surface cone mirroring effects reflect most emitted horizontally then at BLU boundaries, then, finally...
Multi-mode quantum memory is a basic element required for long-distance communication, as well scalable computation. For on-demand readout and long storage times, control pulses are crucial in order to transfer atomic excitations back forth into spin excitations. Here, we introduce noise-robust composite pulse sequences high-fidelity excitation multi-mode memory. These robust the deviations amplitude detuning parameters of realistic conditions. We show efficiency these with typical...
Single rare-earth ions doped in solids are one kind of the promising candidates for quantum nodes towards a scalable network. Realizing universal set high-fidelity gate operations is central requirement functional nodes. Here we propose geometric using hybridized states electron spin and nuclear an ion embedded crystal. The fidelities these gates achieve 0.98 realistic experimental situations. We also show robustness to pulse fluctuations environment decoherence. These results provide...
In this study, the crystal morphology of LiOH·H2O in different solvents was predicated through molecular dynamics (MD) simulation. Modified attachment energy (MAE) model to predict by calculating relative growth rate H2O, CH3CH2OH, and CH3CH2OH/H2O mixed solvent system. The force between face also analyzed. calculated results indicate that main surfaces are (1 1 0), (0 0 1), − (2 1) faces. habit H2O is bulky with a regular shape small aspect ratio. CH3CH2OH rhombus, most important surface 0)...
