- Abstract: We propose a complete architecture for deterministic generation of entangled
multiphoton states. Our approach utilizes periodic driving of a quantum-dot
emitter and an efficient light-matter interface enabled by a photonic crystal
waveguide. We assess the quality of the photonic states produced from a real
system by including all intrinsic experimental imperfections. Importantly, the
protocol is robust against the nuclear spin bath dynamics due to a naturally
built-in refocussing method reminiscent to spin echo. We demonstrate the
feasibility of producing Greenberger-Horne-Zeilinger and one-dimensional
cluster states with fidelities and generation rates exceeding those achieved
with conventional 'fusion' methods in current state-of-the-art experiments. The
proposed hardware constitutes a scalable and resource-efficient approach
towards implementation of measurement-based quantum communication and
computing.

We consider an ensemble of Alkali atoms that are continuously optically pumped and probed.
Due to the collective scattering of photons at large optical depth, the steady state of atoms does not correspond to an uncorrelated tensor-product state.
We find and characterize regimes of Raman lasing, akin to the model of a superradiant laser.
