Physical Review Research, 2023 We develop a nonperturbative formulation based on the Green's function quantization method that can describe spontaneous parametric down-conversion in the high-gain regime in nonlinear optical structures with arbitrary amount of loss and dispersion. This

Cryogenic integrated spontaneous parametric down-conversion
, 2021 Scalable quantum photonics relies on interfacing many optical components under mutually compatible operating conditions. To that end, we demonstrate that spontaneous parametric down-conversion (SPDC) in nonlinear waveguides, a standard technology for ...

Understanding High-Gain Twin-Beam Sources Using Cascaded Stimulated Emission
Physical Review X, 2020 We present a new method for the spectral characterization of pulsed twin-beam sources in the high-gain regime, using cascaded stimulated emission. We show an implementation of this method for a periodically poled potassium titanyl phosphate spontaneous ...

Interaction‐Free Quantum Spectroscopy
Advanced Photonics Research, 2021 Interaction‐free measurement (IFM)‐based single‐photon interference is developed as a powerful platform for revealing object information in quantum metrology, where the presence of a sample is identified without photon “touching” in an interferometer ...

Imaging high-dimensional spatial entanglement with a camera [PDF]
, 2012 The light produced by parametric down-conversion shows strong spatial entanglement that leads to violations of EPR criteria for separability. Historically, such studies have been performed by scanning a single-element, single-photon detector across a ...

FEBS Letters, EarlyView.We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Emerging experimental and computational methods for studying redox‐regulated structural transitions
FEBS Letters, EarlyView.Redox reactions can reshape proteins and alter how they behave in cells, with important consequences for health and disease. This review explores emerging experimental and computational approaches for discovering these redox‐sensitive protein switches, revealing their structural effects, and predicting their behavior, opening new opportunities to ...
