- Abstract: Quantum repeaters are pivotal in the physical layer of the quantum internet.
For its development, quantum repeaters capable of efficient entanglement
distribution are necessary. Quantum repeater schemes based on single-photon
interference are promising due to their potential efficiency. However, schemes
involving first-order interference with photon sources at distant nodes require
stringent phase stability in the components, which poses challenges for
long-distance implementation. In this paper, we present a quantum repeater
scheme that leverages single-photon interference with reduced difficulty of
phase stabilization. Additionally, under specific conditions, we demonstrate
that our scheme achieves a higher entanglement distribution rate between end
nodes compared to existing schemes. This approach, implementable using only
feasible technologies including multimode quantum memories and two-photon
sources, offers high entanglement distribution rates and mild phase
stabilization, leading to the development of multimode quantum repeaters.

We design a passive conditional gate between co-propagating photons using an array of only two-level emitters.
The key resource is to harness the effective photon-photon interaction induced by the chiral coupling of the emitter array to two waveguide modes.
We show how to harness this non-linear phase shift to engineer a conditional, deterministic photonic gate in different qubit encodings.
