Quantum networks will require scalable quantum information processing architectures for fast data rates and reliable communication. Recently, the first memory-enhanced quantum repeater that beats direct photon transmission between two communication nodes was realized[1]. However, achieving the range and speed demanded by proposed quantum applications on the quantum internet requires quantum repeater nodes with many multiplexed memory qubits[2]. In particular, it is necessary to optically excite and measure multiple quantum memories fast and efficiently. In this talk, we will discuss recent experimental progress on multiplexed repeaters based on color centers in diamond, with a particular focus on the efficient fluorescence collection towards high-speed entanglement distribution.
