“…A four‐photon bundle on the other hand would not constrain two frequencies, as is the case of Eqs. (–d) and, beside, it is known that a fourth‐order process is not detectable by a third‐order correlator . Since all the observed resonances are accounted for by the processes highlighted and that, in turn, all these processes produce a resonance in the computed correlation spectrum, the characterization of the photon correlations is indeed comprehensive.…”

Photon correlations between the photoluminescence peaks of the Mollow triplet have been known for a long time, and recently hailed as a resource for heralded single-photon sources. Here, we provide the full picture of photon-correlations at all orders (we deal explicitly with up to four photons) and with no restriction to the peculiar frequency windows that enclose the peaks. We show that a rich multi-photon physics lies between the peaks, due to transitions involving virtual photons, and thereby much more strongly correlated than those transiting through the real states. Specifically, we show that such emissions occur in bundles of photons rather than as successive, albeit correlated, photons. We provide the recipe to frequency-filter the emission of the Mollow triplet to turn it into a versatile and tunable photon source, allowing in principle all scenarios of photon emission, with advantages already at the one-photon level, i.e., providing more strongly correlated heralded single-photon sources than those already known

Self-homodyne measurement of a dynamic Mollow triplet in the solid state

The study of light-matter interaction at the quantum scale has been enabled by the cavity quantum electrodynamics (CQED) architecture, 1 in which a quantum two-level system strongly couples to a single cavity mode. Originally implemented with atoms in optical cavities, 2, 3 CQED effects are now also observed with artificial atoms in solid-state environments. 4-6Such realizations of these systems exhibit fast dynamics, which makes them attractive candidates for devices including modulators and sources in high-throughput communications. However, these systems possess large photon out-coupling rates that obscure any quantum behavior at large excitation powers. Here, we have utilised a self-homodyning 7 interferometric technique that fully employs the complex mode structure of our nanofabricated cavity [8][9][10] to observe a quantum phenomenon known as the dynamic Mollow triplet. 11We expect this interference to facilitate the development of arbitrary on-chip quantum state generators, thereby strongly influencing quantum lithography, metrology, and imaging.The crowning achievement of quantum optics has been to develop a complete theory for the phenomenon of resonant light scattering from a quantized matter system. Beyond providing closure to debates over the nature of light, this theory has enabled observations of uniquely quantum spectacles such as photon antibunching, 4,12 indistinguishable quantum interference, 5,13 and the Mollow triplet. 14, 15The addition of nanoscale resonators to the quantum scattering problem has provided a new frontier in our quest to mould the flow of light. 4-6Here, our reported innovation centres on the investigation of resonant light scattering from a quantum nonlinearity (quantum dot [QD]) strongly coupled to a photonic crystal [PC] cavity. This strong coupling allows for quantum-coherent energy exchange between the resonator's quantized light field and the QD's excitonic field, leading to the formation of light-matter entangled states known as polaritons. 16-18Evidence for the system's strong coupling is provided from the clean avoided-crossing spectra in Fig. 1a. The relative positions of the emission peaks are determined by the transient energies of the Jaynes-Cummings (JC) ladder 19 (Fig. 1b). As the two polaritonic peaks transition of the coupled QD-cavity system obtained when tuning the QD resonance through the cavity mode. By fitting profiles from these spectra, we extract the cavity energy decay rate κ = 2π · 15 GHz and the coherent coupling rate g = 2π · 11 GHz. b, Transient energies for climbing the JC-ladder rung by rung for the first, second and third rung as solid, dashed and dotted lines, respectively.

“…The condition given by (1) implies that the Rabi splitting observed will be given by R = g 2 − γ 2 − and that * nquesada@physics.utoronto.ca the bare mode (light and matter) populations will oscillate at the same modified Rabi frequency [12]. Although the Rabi spliting between the modes can be explained using a classical model, the "quantumness" of the socalled linear Strong Coupling can be observed by other means, such as the counting statistics of the emitted photons [11,14,15]. To evidence quantum behavior in the photoluminescence spectrum not affordable by classical oscillators, one has to consider the case in which more than one photon are bound to the matter.…”

“…Nevertheless, no systematic study has been presented of the dynamics in the non linear regime including decoherence. This is a relevant problem in quantum dots in microcavitites in which the effects of the environment on the quantum dot are quite strong and more importantly the quality factor of the cavities places the system in an intermediate regime [14,19]. Understanding the dynamics of photons and qubits in a regime where the losses are comparable to the light-matter coupling, is relevant in several areas of quantum information processing in which the light mode acts as an information bus between processor qubits [34][35][36][37][38][39] and in general, as a test bed in which multipartite entanglement can be studied [40][41][42][43].…”

Strong coupling of two quantum emitters to a single light mode: The dissipative Tavis-Cummings ladder

A criterion for strong coupling between two quantum emitters and a single resonant light mode in a cavity is presented. The criterion takes into account the escape of cavity photons and the spontaneous emission of the emitters, which are modeled as two level systems. By using such criterion, the dissipative Tavis-Cummings ladder of states is constructed, and it is shown that the inclusion of one more emitter with respect to the Jaynes-Cummings (single emitter) case increases the effective parameter region in which n th order Rabi splitting is observed.
