Quantum state engineering, the cornerstone of quantum photonic technologies, mainly
relies on spontaneous parametric downconversion and four-wave mixing, where one or two …

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

A linearly polarized photon can be quantized from the Lorentz-boosted electromagnetic field
of a nucleus traveling at ultrarelativistic speed. When two relativistic heavy nuclei pass one …

Entangled photon pairs have been used for molecular spectroscopy in the form of entangled
two-photon absorption and in quantum interferometry for precise measurements of light …

In this paper, we revisit the well-known Hong–Ou–Mandel (HOM) effect in which two
photons, which meet at a beamsplitter, can interfere destructively, leading to null in …

Nonlinear interferometers with correlated photons hold promise to advance optical
characterization and metrology techniques by improving their performance and affordability …

Indistinguishability is a crucial element for quantum interference in scalable quantum
information processing. Here, we demonstrate the ability to erase the distinguishability of a …

We analyze and compare the output signals obtained in three different configurations of
optical coherence tomography (OCT). After appropriate processing, these signals are used …

A linearly polarized photon can be quantized from the Lorentz-boosted electromagnetic field
