Experimental time-reversed adaptive Bell measurement towards all-photonic quantum repeaters

Storage-free quantum repeaters represent a viable alternative to quantum-memory-based ones. Here, the authors propose a modified scheme for Bell state measurements which reduces the necessary resources for realising such an all-photonic repeater, and show a proof-of-principle implementation.
