Abstract: We have theoretically studied the scattering of two-photon pulses from a spatially-separated array of two-level atoms coupled to the waveguide. A general analytical expression for the scattered pulse has been obtained. The contributions of various single-eigenstate and double-excited eigenstates of the array have been analyzed. We have also calculated the dependence of the time incident photons are stored in the array on its period and the number of atoms. The largest storage times correspond to the structures with the anti-Bragg period, equal to the quarter of the wavelength of light at the atom resonance frequency $\lambda/4$.

We show that the atomic entanglement emerges in the course of relaxation and persists in the final steady state of the system. Our findings open a new way to engineer dissipation-induced entanglement.

We show that after transmission of a short few-photon pulse, the final state of the atom and all the photons is a genuine multipartite entangled state belonging to the W class. The parameters of the input pulse are optimized to maximize the efficiency of three- and four-partite W-state production.

Resonant Parametric Photon Generation in Waveguide-coupled Quantum Emitter Arrays [83.88591755871734]
We have developed a theory of parametric photon generation in the waveguides coupled to arrays of quantum emitters with temporally modulated resonance frequencies. Such generation can be interpreted as a dynamical Casimir effect. We demonstrate numerically and analytically how the emission directionality and photon-photon correlations can be controlled by the phases of the modulation.

Detecting the relative phase between different frequency components of a photon using a three-level $Λ$ atom coupled to a waveguide [0.9374652839580183]
We study the scattering of a single photon propagating along a waveguide in an arbitrary superposition state two frequencies with a single three-level $Lambda$ atom in a superposition of two non-degenerate ground states where the atom is coupled to a waveguide. Our results show that a three-level $Lambda$ atom coupled to a waveguide can be used as photon phase filter that could detect the relative phase between the two frequencies of the photon superposition state.

We observe a weak guided light field transmitted through an ensemble of atoms and an optical nanofiber. From the measured squeezing spectrum we gain access to the phase and amplitude of the energy-time entangled part of the two-photon wavefunction. Our characterization of the entangled two-photon component constitutes a diagnostic tool for quantum optics devices.

Entanglement dynamics in dissipative photonic Mott insulators [62.997667081978825]
In spite of particle losses the quantum entanglement propagation exhibits a ballistic character with propagation speeds related to the differerent quasiparticles that are involved in the dynamics. Our analysis reveals that photon dissipation has a strikingly asymmetric behavior in the two configurations with a much more dramatic role on the holon entanglement propagation than for the doublon case.
