Spontaneous parametric down-conversion (SPDC) has been a key enabling technology in
exploring quantum phenomena and their applications for decades. For instance, traditional …

Non-Gaussian states with Wigner negativity are of particular interest in quantum technology
due to their potential applications in quantum computing and quantum metrology. However …

Non-classical states of light, such as entangled photon pairs and number states, are
essential for fundamental tests of quantum mechanics and optical quantum technologies …

Abstract Entanglement and Einstein–Podolsky–Rosen (EPR) steering are nonlocal quantum
correlations, which are relevant resources for quantum information protocols. EPR steering …

We investigate the quantum entanglement of the three modes associated with the three-
photon states obtained by triple-photon generation in a phase-matched third-order nonlinear …

Very recently, strongly non-Gaussian states have been observed via a direct three-mode
spontaneous parametric down-conversion in a superconducting cavity [Phys. Rev. X 10 …

We present an experimental proposal for the generation of photon triplets based on third-
order spontaneous parametric downconversion in thin optical fibers. Our analysis includes …

We study the third-order spontaneous parametric down-conversion (TOSPDC) process, as a
means to generate entangled photon triplets. Specifically, we consider thin optical fibers as …

Optical fibers have been considered an optimal platform for third-order parametric down-
conversion since they can potentially overcome the weak third-order nonlinearity by their …

Triple-photon states generated by three-mode spontaneous parametric down-conversion
are the paradigm of unconditional non-Gaussian states, essential assets for quantum …
