Improving SPDC single-photon sources via extended heralding and feed-forward control
New Journal of Physics, 2019 Evolving photonic quantum technologies and applications require higher and higher rates of single photon generation. In parallel, it is required that these generated photons are kept spectrally pure for multi-photon experiments and that multi-photon ...

Nanowire-based integrated photonics for quantum information and quantum sensing
Nanophotonics, 2023 At the core of quantum photonic information processing and sensing, two major building pillars are single-photon emitters and single-photon detectors. In this review, we systematically summarize the working theory, material platform, fabrication process,

Observing multifarious topological phase transitions with real-space indicator
Nanophotonics, 2021 First- and second-order topological phases, capable of inherent protection against disorder of materials, have been recently experimentally demonstrated in various artificial materials through observing the topologically protected edge states ...

An efficient integrated two-color source for heralded single photons
New Journal of Physics, 2013 We present a pulsed and integrated, highly non-degenerate parametric down-conversion (PDC) source of heralded single photons at telecom wavelengths, paired with heralding photons around 800 nm.

Coherent interaction of atoms with a beam of light confined in a light cage
Light: Science & Applications, 2021 Light-matter interaction in the hollow-core light cage, at the example of EIT in alkali atoms in this work, presents a novel approach to implement integrated on-chip devices for applications in quantum optics and quantum information.

Quantum superposition demonstrated higher-order topological bound states in the continuum
Light: Science & Applications, 2021 Higher-order topological insulators, as newly found non-trivial materials and structures, possess topological phases beyond the conventional bulk-boundary correspondence. In previous studies, in-gap boundary states such as the corner states were regarded

Characterisation of fabrication inhomogeneities in Ti:LiNbO3 waveguides
New Journal of Physics, 2019 Nonlinear processes in integrated, guiding systems are fundamental for both classical and quantum experiments. Integrated components allow for compact, modular and stable light-processing systems and as such their use in real-world systems continues to ...

Nanodiamonds carrying silicon-vacancy quantum emitters with almost lifetime-limited linewidths
New Journal of Physics, 2016 Colour centres in nanodiamonds are an important resource for applications in quantum sensing, biological imaging, and quantum optics. Here we report unprecedented narrow optical transitions for individual colour centres in nanodiamonds smaller than 200 ...

Driven discrete time quantum walks
New Journal of Physics, 2016 We introduce the driven discrete time quantum walk (QW), where walkers are added during the walk instead of only at the beginning. This leads to interference in walker number and very different dynamics when compared to the original QW.

Compact component for integrated quantum optic processing [PDF]
Scientific Reports, 2015 AbstractQuantum interference is indispensable to derive integrated quantum optic technologies (1–2). For further progress in large scale integration of quantum optic circuit, we have introduced first time two mode interference (TMI) coupler as an ultra compact component.
