摘要:

最近在金刚石中发现的带负电荷的锡空位中心在量子信息处理(QIP)中具有很好的应用前景。我们在这里提出了一个详细的光谱研究,包括单光子发射和偏振特性,发射光谱的温度依赖性以及声子边带和Debye-Waller因子的详细分析。利用光致发光激发光谱(PLE),我们探测了一个能量较高的激发态,并证明了在低温下的单发射体的完全寿命有限的线宽。对于这些发射器,我们还调查了共振激发下的电荷态的稳定性。这些结果提供了一个详细的洞察光谱特性的$\text{SnV}^-$中心,并奠定了基础,为进一步研究其在QIP的适用性。

英文摘要:

The recently discovered negatively charged tin-vacancy centre in diamond is a promising candidate for applications in quantum information processing (QIP). We here present a detailed spectroscopic study encompassing single photon emission and polarisation properties, the temperature dependence of emission spectra as well as a detailed analysis of the phonon sideband and Debye-Waller factor. Using photoluminescence excitation spectroscopy (PLE) we probe an energetically higher lying excited state and prove fully lifetime limited linewidths of single emitters at cryogenic temperatures. For these emitters we also investigate the stability of the charge state under resonant excitation. These results provide a detailed insight into the spectroscopic properties of the $\text{SnV}^-$ centre and lay the foundation for further studies regarding its suitability in QIP.
