| Summary: | 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. |
