Optical cavities or metallic antennas are frequently used to enhance interactions between light and a single quantum emitter. WE argue that hybrid systems combining an antenna and a cavity can achieve stronger interactions than the cavity or antenna alone. Through subtle interference effects, these systems can break the fundamental limit for single antennas and benefit simultaneously from the long photon lifetime in the cavity and the strong confinement near the antenna. As highlighted by the example on the cover, this also causes stronger light emission than in a cavity only.
