- Abstract: We develop a scheme of generating highly indistinguishable single photons
from an active quantum Su-Schrieffer-Heeger chain made from a collection of
noisy quantum emitters. Surprisingly, the single photon emission spectrum of
the active quantum chain is extremely narrow compared to that of a single
emitter or topologically trivial chain. Moreover, this effect becomes
dramatically strong close to the non-trivial-to-trivial phase transition point.
Using this effect, we show that the single photon linewidth of a long
topological quantum chain can become arbitrarily narrow, constituting an ideal
source of indistinguishable single photons. Finally, taking specific examples
of actual quantum emitters, we provide a microscopic and quantitative analysis
of our model and analyze the most important parameters in view of the
experimental realization.

We study the single photon transport properties in periodic and position-disordered Jaynes-Cummings arrays.
In the disordered case, we find that the single photon transmission curves show the disappearance of band formation.

We show that the single-photon nonlinearity vanishes with the number of emitters.
The mechanism behind this behavior is the quantum Zeno effect, manifested in the slowdown of the photon-controlled dynamics.

We present the experimental characterization of both coherent and statistical properties of light emitted from ensembles of trapped ions.
We show how super-Poissonian quantum statistics non-trivially arises purely from the finite number of indistinguishable single-photon emitters.
The achieved new optical emission regime provides a new perspective on the emergence of optical coherence at the atomic scale.

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.

We introduce a single-photon detector design operating in the microwave domain based on a weakly nonlinear metamaterial.
We show that the single-photon detection fidelity increases with the length of the metamaterial to approach one at experimentally realistic lengths.
In stark contrast to conventional photon detectors operating in the optical domain, the photon is not destroyed by the detection and the photon wavepacket is minimally disturbed.
