      abstract     = {Defects in wide-band-gap semiconductors are promising qubit
                      candidates for quantum communication and computation.
                      Epitaxially grown II-VI semiconductors are particularly
                      promising host materials due to their direct band gap and
                      potential for isotopic purification to a spin-zero nuclear
                      background. Here, we show an alternative type of single
                      photon emitter with potential electron spin qubits based on
                      Cl impurities in ZnSe. We utilize a quantum well to increase
                      the binding energies of donor emission and confirm single
                      photon emission with short radiative lifetimes of 192 ps.
                      Furthermore, we verify that the ground state of the Cl donor
                      complex contains a single electron by observing
                      two-electron-satellite emission, leaving the electron in
                      higher orbital states. We also characterize the Zeeman
                      splitting of the exciton transition by performing
                      polarization-resolved magnetic spectroscopy on single
                      emitters. Our results suggest single Cl impurities are
                      suitable as a single photon source with a potential photonic
                      interface.},
