- Abstract: We demonstrate the resonant excitation of two quantum dots in a photonic
integrated circuit for on-chip single-photon generation in multiple spatial
modes. The two quantum dots are electrically tuned to the same emission
wavelength using a pair of isolated $p$-$i$-$n$ junctions and excited by a
resonant pump laser via dual-mode waveguides. We demonstrate two-photon quantum
interference visibility of $(79\pm2)\%$ under continuous-wave excitation of
narrow-linewidth quantum dots. Our work solves an outstanding challenge in
quantum photonics by realizing the key enabling functionality of how to
scale-up deterministic single-photon sources.

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.

We identify few-photon scattering mechanisms that lead to a full inversion of the emitter while transferring off-resonant photons from one mode to another.
Our results can be understood as quantized analogue of the recently developed off-resonant quantum control scheme known as Swing-UP of quantum EmitteR.

Entanglement in high-dimensional quantum systems, where one or more degrees of freedom of light are involved, offers increased information capacities and enables new quantum protocols.
