Quantifying tripartite spatial and energy-time entanglement in nonlinear optics
Physical Review Research, 2022 In this work, we provide a means to quantify genuine tripartite entanglement in arbitrary (pure and mixed) continuous-variable states as measured by the tripartite entanglement of formation—a resource-based measure quantifying genuine multipartite ...

Spontaneous Parametric Down-Conversion and Quantum Entanglement
, 2017 Quantum entanglement has been a topic of much research in modern physics, and an application in quantum computing is envisioned. This thesis address the use of polarization entangled photon pairs produced by spontaneous parametric down-conversion (SPDC) in entanglement transfer process and quantum computing. The simplicity of SPDC entanglement relative

Photon correlations in type-I optical parametric down-conversion
, 2000 We develop a quantum theory for photon-pair correlations in type-I spontaneous parametric down-conversion, including crystal dispersion. We obtain different amplitudes for the correlations of degenerate (identical frequencies) and non-degenerate ...

Stimulated emission tomography for efficient characterization of spatial entanglement
Physical Review ResearchStimulated-emission tomography (SET) is an excellent tool for characterizing the process of spontaneous parametric down conversion (SPDC), which is commonly used to create pairs of entangled photons for use in quantum information protocols.
