The deterministic integration of quantum emitters into on-chip photonic elements is crucial for the implementation of scalable on-chip quantum circuits. Here, we report on the deterministic integration of single quantum dots (QD) into tapered multimode interference beam splitters using in-situ electron beam lithography (EBL). We demonstrate the functionality of the deterministic QD-waveguide structures by µPL spectroscopy and by studying the photon cross-correlation between the two MMI output ports. The latter confirms single-photon emission and on-chip splitting associated with g(2)(0) << 0.5. Moreover, the deterministic integration of QDs enables the demonstration and controlled study of chiral light-matter effects and directional emission in QD-WGs, and the realization of low-loss heterogenous QD-WG systems with excellent quantum optical properties.

Nanocativies enable a wide range of weak and strong light-matter coupling phenomena at the single molecule level. In this talk, I will explore classical and quantum optical effects behind strong plasmon-molecule interactions, with particular focus on two different topics. First, I will treat the quantization of the electromagnetic fields in both purely metallic and hybrid metallo-dielectric nanostructures. Secondly, I will explore the impact of molecular vibrations in the so-called plasmonic Purcell effect.

The transport of quantum states without loss of "coherence" is extremely important for realizing quantum information systems. Quantum effects have been demonstrated in exotic systems, such as cold atoms suspended in magnetic fields, but these systems are extremely challenging to realise. In this work we will translate this work into the chemical domain, using thin films of "J-aggregates". These J-aggregates are quantum many-body systems characterized by the sharing of excitonic states over two or more molecules. This novel organic quantum soft-matter platform can confine the light at the nanoscale taking the advantages of supramolecular chemistry to design properties on demand.

In the classical Hong-Ou-Mandel (HOM) effect pairs of photons with bosonic (fermionic) spatial wavefunction coalesce (anti-coalesce) when mixed on a lossless beamsplitter. Here we report that the presence of dissipation in the beamsplitter allows the observation of the anti-HOM effect, where bosons anti-coalesce and fermions show coalescent-like behavior. We provide an experimental demonstration of the anti-HOM effect for both bosonic and fermionic two-photon entangled states. Beyond its fundamental significance, the anti-HOM effect offers applications in quantum information and metrology where states of entangled photons are dynamically converted.
