“…33 We show control over this routing using both temperature tuning and via the excitation intensity, with the latter requiring a critical photon number of only 0.94 photons per lifetime. Altogether, our platform enables coherent light-matter scattering 31 and efficient quantum optical nonlinearities 32,42 at the single-photon level, two key functionalities of solid-state quantum technologies. where we consider decay into the cavity mode, non-radiative channels and non-cavity modes respectively.…”

Tailored photonic cavities allow enhancing light-matter interaction ultimately to create a fully coherent quantum interface. Here, we report on an integrated microdisk cavity containing self-assembled quantum dots to coherently route photons between different access waveguides. We measure a Purcell factor of F exp = 6.9 ± 0.9 for a cavity quality factor of about 10,000, allowing us to observe clear signatures of coherent scattering of photons by the quantum dots. We show how this integrated system can coherently re-route photons between the drop and bus ports, and how this routing is controlled by detuning the quantum dot and resonator, or through the strength of

“…We start from the artificial atoms, semiconductor quantum dots (QDs) (Foster et al, 2019;Le Jeannic et al, 2021;Thyrrestrup et al, 2018;Versteegh et al, 2014), that operate in the near infrared or visible spectra range. The main advantage of the QD platform is the fact that they are incorporated in the bulk of the photonic structure, which results in the relatively high coupling factors β which may reach 99% at cryogenic temperatures (Scarpelli et al, 2019).…”

This review describes an emerging field of waveguide quantum electrodynamics (WQED) studying interaction of photons propagating in a waveguide with localized quantum emitters. In such systems, atoms and guided photons are hybridized with each other and form polaritons that can propagate along the waveguide, contrary to the cavity quantum optics setup. Emerging in such a system collective light-atom interactions result in super-and sub-radiant quantum states, that are promising for quantum information processing, and give rise to peculiar quantum correlations between photons. The review is aimed at both experimentalists and theoreticians from various fields of physics interested in the rapidly developing subject of WQED. We highlight recent groundbreaking experiments performed for different quantum platforms, including cold atoms, superconducting qubits, semiconductor quantum dots, quantum solid-state defects and at the same time provide a comprehensive introduction into various theoretical techniques to study atom-photon interactions in the waveguide.

“…In a setup of light-matter interacting quantum interface with collective dipole-dipole interactions [23,24], a strongly-coupled atom-waveguide system [25,26] presents subradiant dynamics [27][28][29] which sustains for a longer lifetime and thus suffices to simulate Anderson-like localization of a quenched single atomic excitation [30,31]. The atomwaveguide system has been shown to manifest mesoscopic entanglement [32], photon-photon correlations [33,34], longrange correlated spin dimers [35,36], and bounded multiatom excitations [37]. It also allows tunable nonreciprocal couplings in the guided modes of the waveguide to realize a new research paradigm of chiral quantum optics [38][39][40] and topological waveguide quantum electrodynamics [41,42] Here we theoretically study quantum correlations via Kubo cumulant expansions [43] in an atomic chain coupled to the waveguide.…”

Atom-waveguide interface mediates significant and long-range light-matter interactions through the guided modes. In this one-dimensional system, we theoretically investigate the excitation localization of multiple atomic excitations under strong position disorders. Deep in the localization side, we obtain the time evolutions of quantum correlations via Kubo cumulant expansions, which arise initially and become finite and leveled afterward, overtaking the ones without disorders. This indicates two distinct regimes in time: before the onset of excitation localization, the disorders engage the disturbance of quantum correlations, which is followed by disorder-assisted build-up of quantum correlations that maintain at a later stage owing to the absence of excitations diffusion. The crossing of distinct regimes is pushed further in time for longer-range correlations, which indicates a characteristic timescale needed for disorders to sustain them. We also explore the effect of directionality of couplings and resonant dipole-dipole interactions, which can drive the system toward the delocalized side when it is under chiral couplings or large dipole-dipole interaction strengths. The time-evolved quantum correlations can give insights to the studies of few-body localization phenomenon and nonequilibrium dynamics in open quantum systems.
