从系综测量可知，固体仲氢中的铷原子具有良好的磁场量子传感特性。为了将单个铷原子用作量子传感器，需要能够有效地测量单个原子的内部状态的技术，例如激光诱导荧光。在这项工作中，我们寻找激光诱导荧光从合奏的铷原子被困在固体仲氢，分别在固体氖。在仲氢中，我们没有发现荧光的证据，在探索的范围内，我们把辐射分支比的上限。在氖中，我们观察到激光诱导荧光，测量发射光的光谱，并测量基质中的激发态寿命。还报道了来自激发光的原子的漂白。
It is known from ensemble measurements that rubidium atoms trapped in solid parahydrogen have favorable properties for quantum sensing of magnetic fields. To use a single rubidium atom as a quantum sensor requires a technique capable of efficiently measuring the internal state of a single atom, such as laser-induced fluorescence. In this work we search for laser-induced fluorescence from ensembles of rubidium atoms trapped in solid parahydrogen and, separately, in solid neon. In parahydrogen we find no evidence of fluorescence over the range explored, and we place upper limits on the radiative branching ratio. In neon, we observe laser-induced fluorescence, measure the spectrum of the emitted light, and measure the excited-state lifetime in the matrix. Bleaching of atoms from the excitation light is also reported.
