Nearly 30 years ago, two-photon interference was observed, marking the beginning of a
new quantum era. Indeed, two-photon interference has no classical analogue, giving it a …

Surface plasmon polaritons (SPPs) are electromagnetic excitations coupled to electron-
charge density waves at metal-dielectric interfaces. They have recently been found to …

Hong–Ou–Mandel interferometers are valuable tools in many Quantum Information and
Quantum Optics applications that require photon indistinguishability. The theoretical limit for …

Quantum key distribution (QKD) guarantees unconditional communication security based on
the laws of quantum physics. However, practical QKD suffers from a number of quantum …

Bell state measurement (BSM) plays crucial roles in photonic quantum information
processing. The standard linear optical BSM is based on Hong-Ou-Mandel interference …

Multiphoton interference is an important phenomenon in modern quantum mechanics and
experimental quantum optics, and it is fundamental for the development of quantum …

Measurement-device-independent quantum key distribution (MDI QKD) is a promising and
practical protocol for remote secret sharing, where the Hong-Ou-Mandel (HOM) type …

Interference between two completely independent photons lies at the heart of many photonic
quantum information applications such as quantum repeaters, teleportation, and quantum …

We present a spectral characterization of two-photon nonclassical interference on a beam
splitter (BS) between a weak coherent state source and another source, which emits a …

Abstract Recently, the Hong–Ou–Mandel (HOM) interference between two independent
weak coherent pulses (WCPs) has been paid much attention due to the measurement …
