论文摘要
有效的量子存储器对于长距离量子通信以及复杂的大规模计算体系结构至关重要。我们研究了ER $^{3+} $的功能：y $ _2 $ SIO $ _5 $ CRYSTAL，通过采用用于密集的光学合奏开发的技术来充当旅行微波光子的量子内存。为了做到这一点，我们进行了ER $^{3+} $的高分辨率微波光谱：y $ _2 $ sio $ _5 $，我们在其中确定了电子旋转以及超细过渡。此外，我们已经探索了光谱孔燃烧技术，并研究了Millikelvin温度下的自旋松弛过程，确定了主要的放松机制，这为该主题的进一步研究奠定了基础。
Efficient quantum memory is of paramount importance for long-distance quantum communications, as well as for complex large-scale computing architectures. We investigate the capability of Er$^{3+}$:Y$_2$SiO$_5$ crystal to serve as a quantum memory for the travelling microwave photons by employing techniques developed for dense optical ensembles. In our efforts to do so, we have performed high-resolution microwave spectroscopy of Er$^{3+}$:Y$_2$SiO$_5$, where we identified electronic spin as well as hyperfine transitions. Furthermore, we have explored spectral hole burning technique and studied the spin relaxation process at millikelvin temperatures, determined the main relaxation mechanisms, which lay the groundwork for further studies of the topic.
