Multiplexed trapped-ion quantum repeaters allow for high-rate communications between distant quantum computers, and the ability to co-trap multiple ion species means there is no need to compromise between qubit lifetime and interfacing capability. Here, the authors show a significant improvement in entanglement distribution rates by considering a time-multiplexed quantum repeater protocol and treating the time step as a free parameter in such networks.
