This theory project is concerned with quantum states of light fields and spin systems and their application in quantum information and communication. Light is coupled to or emitted from a system of many spins, while measurements on either the spins or the optical field conditionally prepare non-Gaussian light or spin states, respectively, beyond a single excitation. The focus is on bosonic spin modes where all light-matter interactions, channel evolutions, and measurements occur collectively. As a crucial element we explore active or passive methods for suppressing loss with structured and unstructured atomic systems.
