• Abstract summary: 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.

• Abstract: 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. We find that the scattering depends on both the relative phase between the photon frequencies and the relative phase between the atomic ground states. 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 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.

  We study the dynamics of a coherent feedback network where two two-level atoms are coupled with a semi-infinite waveguide. The photons can be emitted into the waveguide via the nonchiral or chiral couplings between the atom and the waveguide. The photonic state in the waveguide is analyzed in the frequency domain and the spatial domain.

  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.

  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. Here, we demonstrate a functional source of high-dimensional, noise-resilient hyperentangled states encoded in time-frequency and vector-vortex structured modes. We generate highly entangled photon pairs at telecom wavelength that we characterise via two-photon interference and quantum state tomography, achieving near-unity visibilities and fidelities.

  In this paper, we investigate the single-photon scattering and bound states in a one-dimensional coupled-resonator waveguide. When the atom couples to the waveguide via two resonators, the single-photon reflection rate is characterized by either Breit-Wigner or Fano line shapes. We also find a phase transition phenomena for the multi-resonator coupling case, which reveals that the upper bound state only exists when the atom-waveguide coupling strength is above a critical value.
