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

An efficient source of quantum-correlated photon-pairs that is integrable with existing silicon-
electronics fabrication techniques is desirable for use in quantum photonic integrated …

We report an all-fiber telecom-band energy-time entangled biphoton source with all physical
elements integrated into a compact cabinet. At a pump power of 800 µW, the photon pairs …

Quantum entanglement is an integral part of quantum optics and has been exploited in
areas such as computation, cryptography and metrology. The entanglement between …

In this paper, we present a design of an all-fiber source of correlated photon pairs based on
standard telecommunications tapered fibers. We examine the generation of correlated …

Quantum information is often carried in the frequency and polarization degrees of freedom
(DoFs) in single photons and entangled photons. We demonstrate an approach to couple …

The temperature dependence of the refractive indices of potassium titanyl phosphate (KTP)
is shown to enable quasi-phasematched type II spontaneous parametric downconversion …

This paper investigates the mathematical model of the quantum wavelength-division-
multiplexing (WDM) network based on the entanglement distribution with the least required …

Spectrally pure photons heralded from unentangled photon pair sources are crucial for any
quantum optical system reliant on the multiplexing of heralded photons from independent …
