Entangled photon pairs are a critical resource in quantum communication protocols ranging
from quantum key distribution to teleportation. The current workhorse technique for …

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

Entangled quantum particles have correlations stronger than those allowed by classical
physics. These correlations are at the heart of deep foundational questions in quantum …

The Abbe–Rayleigh diffraction limit constrains spatial resolution for classical imaging
methods. Quantum imaging exploits correlations between photons to reproduce structures …

Multiparticle quantum interference is critical for our understanding and exploitation of
quantum information, and for fundamental tests of quantum mechanics. A remarkable …

We show that the states generated by a three-mode spontaneous parametric down-
conversion (SPDC) interaction Hamiltonian possess tripartite entanglement of a different …

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 …

All-fiber systems for third harmonic generation are of great interest because they can be
used for the inverse process, namely, the generation of entangled photon triplets. Usually …

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 …
