Abstract Hong–Ou–Mandel (HOM) interference—the bunching of indistinguishable photons
at a beamsplitter—is a staple of quantum optics and lies at the heart of many quantum …

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

As first demonstrated by Hanbury Brown and Twiss, it is possible to observe interference
between independent light sources by measuring correlations in their intensities rather than …

Quantum interferences of entangled photons have engendered tremendous intriguing
phenomena that lack any counterpart in classical physics. Hitherto, owing to the salient …

Quantum correlation of two‐photon states is utilized to suppress the environmental noise in
imaging down to the single‐photon level. However, the size of the coherence area of the …

Two-photon interference is an important effect that is tightly related to the quantum nature of
light. Recently, it has been shown that the photon bunching from the Hong–Ou–Mandel …

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 …

Quantum interferometry based on induced-coherence phenomena has demonstrated the
possibility of undetected-photon measurements. Perturbation in the optical path of probe …

Hong-Ou-Mandel (HOM) interferometry is a powerful quantum metrology technique to
reconstruct the surface-depth profile of transparent samples with complementary benefits of …
