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

Pixelation occurs in many imaging systems and limits the spatial resolution of the acquired
images. This effect is notably present in quantum imaging experiments with correlated …

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

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 …

In this work, a theoretical generalization of Lloyd's quantum illumination model for signal
beams described by two entangled photon states is developed. It is shown that the new …

In ultra-and deep-strong cavity quantum electrodynamics (QED) systems, many intriguing
phenomena that do not conserve the excitation number are expected to occur. In this paper …

Linear quantum optics is advancing quickly, driven by sources of correlated photon pairs.
Multi-photon sources beyond pairs would be a powerful resource, but are a difficult …

The theory of third-order spontaneous parametric down-conversion (TOSPDC) in a ring
waveguide microcavity is developed. Analytical expressions for the rate of photon triplet …

Quantum hyper-entangled system with multiple qubits have garnered significant interest and
are considered essential resources for various quantum applications. The generation of …

Spontaneous parametric down-conversion (SPDC) has been one of the foremost tools in
quantum optics for over five decades. Over that time, it has been used to demonstrate some …
