外文摘要：Efficient detection of single optical centres in solids is essential for quantum information processing,sensing and single-photon generation applications.In this work,we use radio-frequency(RF)reflectometry to electrically detect the photoionisation induced by a single Er3+ion in Si.The high bandwidth and sensitivity of the RF reflectometry provide sub-100-ns time resolution for the photoionisation detection.With this technique,the optically excited state lifetime of a single Er3+ion in a Si nano-transistor is measured for the first time to be 0.49±0.04 μs.Our results demonstrate an efficient approach for detecting a charge state change induced by Er excitation and relaxation.This approach could be used for fast readout of other single optical centres in solids and is attractive for large-scale integrated optical quantum systems thanks to the multi-channel RF reflectometry demonstrated with frequency multiplexing techniques.
