Atomic systems are at the frontier of many areas of quantum science and technology, including sensing and metrology, quantum simulation and quantum information processing. In this talk, I will present our work on developing novel atomic systems in the solid-state to advance these applications. In particular, I will describe our work on Er3+ ions in solid crystalline hosts, which have a number of unique advantages including telecom-wavelength operation and compatibility with a broad range of host materials. By engineering their optical transitions with with silicon nanophotonic circuits, we have demonstrated the first atomic source of single photons in the telecom band, as well as high-fidelity single-shot readout of a single ion’s spin. Furthermore, we have demonstrated optical addressing and manipulation of multiple ions with spacings below the diffraction limit of light, using a novel frequency-domain super-resolution technique, which is promising for manipulating dense atomic arrays with strong spin-spin interactions. These are promising steps towards realizing quantum technologies such as telecom-band quantum networks, as well as controllable, coherent strongly-interacting spin systems.
