Advances in high quality optical, electrical, and mechanical systems have led to the observation of quantum coupling between photons and phonons in both the radio frequency and optical domain. This opens up new frontiers, including circuit quantum electrodynamics, ground state cooling of macroscopic mechanical systems, and the coherent transduction of single quanta from radio frequency to optical frequency excitations. I consider the direct impact of these advances on outstanding challenges in quantum information science and metrology, showing how one can beat the standard quantum limit for force detection, make single-photon-level radio-frequency observations in room temperature systems, develop long-range coherent coupling between distant atomic ionic spins, and even implement integer and fractional quantum hall states of light.
