In this paper, we demonstrate the generation of high-performance entangled photon-pairs in
different degrees of freedom from a single piece of fiber pigtailed periodically poled LiNbO3 …

Integrated photon-pair sources are crucial for scalable photonic quantum systems. Thin-film
lithium niobate is a promising platform for on-chip photon-pair generation through …

Heralded single-photon source (HSPS) intrinsically suffers from the trade-off between the
heralded single-photon rate and the single-photon purity. To break through this trade-off …

We generate quantum-correlated photon pairs using cascaded χ^(2): χ^(2) traveling-wave
interactions for second-harmonic generation (SHG) and spontaneous parametric down …

Discrete frequency-bin entanglement is an essential resource for applications in quantum
information processing. In this Letter, we propose and demonstrate a scheme to generate …

To advance the full potential of quantum networks one should be able to distribute quantum
resources over long distances at appreciable rates. As a consequence, all components in …

Entangled photons are important for testing foundations of quantum physics and are at the
heart of quantum technology. Integrated photonics has overwhelming dominance in terms of …

We explore the cascaded second-order (χ (2)) nonlinear process of second-harmonic
generation (SHG)+ spontaneous parametric down-conversion (SPDC) at telecom …

When implementing O-band quantum key distribution on optical fiber transmission lines
carrying C-band data traffic, noise photons that arise from spontaneous Raman scattering or …

This thesis represents a summary of the activities I performed throughout my PhD, mainly on
quantum optics in the infrared. The field of quantum optics was revolutionised by the …
