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 ...

Dispersion-enabled quantum state control in integrated photonics
, 2016 Integrated optics has brought unprecedented levels of stability and performance to quantum photonic circuits. However, integrated devices are not merely micron-scale equivalents of their bulk-optics counterparts.

Robust quantum state engineering through coherent localization in biased-coin quantum walks [PDF]
, 2018 We address the performance of a coin-biased quantum walk as a generator for non-classical position states of the walker. We exploit a phenomenon of coherent localisation in the position space --- resulting from the choice of small values of the coin ...

Optical scatter of quantum noise filter cavity optics
, 2015 Optical cavities to filter squeezed light for quantum noise reduction require optics with very low scattering losses. We report on measured light scattering from two super-polished fused silica optics before and after applying highly-reflective ion-beam ...

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 ...

High performance guided-wave asynchronous heralded single photon source [PDF]
, 2005 We report on a guided wave heralded photon source based on the creation of non-degenerate photon pairs by spontaneous parametric down conversion in a Periodically Poled Lithium Niobate waveguide.

FEBS Open Bio, EarlyView.Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐
