• Abstract: We propose a source of entangled multiphoton states based on spontaneous emission from a ladder of a cascaded quantum well structure. The coupling between the quantum wells enables a many-path evolution with the emission of photon-number combination states in three modes. The multiphoton state has unique properties, such as control of the entanglement between two multiphoton modes by measuring the third. We discuss briefly an application as a qubit-pair source with an error-detection ancilla.

• Few-Photon SUPER: Quantum emitter inversion via two off-resonant photon modes [0.0]
  We investigate an extended Jaynes-Cummings model where two photon modes are coupled off-resonantly to a quantum emitter. We identify few-photon scattering mechanisms that lead to a full inversion of the emitter while transferring off-resonant photons from one mode to another. Our results can be understood as quantized analogue of the recently developed off-resonant quantum control scheme known as Swing-UP of quantum EmitteR.

The parameters of the input pulse are optimized to maximize the efficiency of three- and four-partite W-state production.

We show that their combination leads to a neat picture compatible with perturbative two-photon scattering. This should help to control, enhance and open new regimes of multiphoton emission.

  We propose a scheme that generates multi-photon bundles via virtual excitations in a quantum Rabi model. We show that the driving pulses induce deterministic emission of multiple photons from the eigenstates of the quantum Rabi model. We calculate the generalized second-order correlation functions of the output photons, which reveal that the emitted photons form antibunched multi-photon bundles.

  We consider an ensemble of Alkali atoms that are continuously optically pumped and probed. Due to the collective scattering of photons at large optical depth, the steady state of atoms does not correspond to an uncorrelated tensor-product state. We find and characterize regimes of Raman lasing, akin to the model of a superradiant laser.

  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.
