- Abstract summary: We investigate coherent single-photon transport in a waveguide-QED structure containing two giant atoms.
We find that the appearance of Fano line shapes is influenced by not only the phase delays between coupling points but also the topologies of system.
These phenomena may provide powerful tools for controlling and manipulating photon transport in future quantum networks.

- Abstract: We investigate coherent single-photon transport in a waveguide-QED structure
containing two giant atoms. The unified analytical expressions of the
single-photon scattering amplitudes applicable for different topological
configurations are derived. The spectroscopic characteristics in different
parameter regimes, especially the asymmetric Fano line shapes and the
electromagnetically induced transparency (EIT)-like spectra, are analyzed in
detail. Specifically, we find that the appearance of Fano line shapes is
influenced by not only the phase delays between coupling points but also the
topologies of system. We also summarize the general conditions for appearance
of EIT-like spectra by analyzing the master equation and verify these
conditions by checking the corresponding analytical expressions of the
scattering spectra. These phenomena may provide powerful tools for controlling
and manipulating photon transport in future quantum networks.

We investigate the single-photon scattering spectra of a giant atom coupled to a one dimensional waveguide via multiple connection points or a continuous coupling region.
We find that under the Markovian limit, the phase decay is detuning-independent, resulting in Lorentzian lineshapes.
In the non-Markovian regime, the accumulated phases become detuning-dependent, giving rise to non-Lorentzian lineshapes.

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.

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.
