Photons have been a flagship system for studying quantum mechanics, advancing quantum
information science, and developing quantum technologies. Quantum entanglement …

Communication security has to evolve to a higher plane in the face of the threat from the
massive computing power of the emerging quantum computers. Quantum secure direct …

Of all oxides, lithium niobate (LiNbO_3) is the gold standard electro-optical material in fiber-
optic transmission systems. Modulators based on diffused waveguides in bulk LiNbO_3 …

Quantum communication requires the transfer of quantum states, or quantum bits of
information (qubits), from one place to another. From a fundamental perspective, this allows …

Abstract Applications of Integrated Optics to quantum sources, detectors, interfaces,
memories and linear optical quantum computing are described in this review. By their …

We put forward the concept of quantum spiral bandwidth of the spatial mode function of the
two-photon entangled state generated in spontaneous parametric down-conversion. We …

We study theoretically the generation of photon pairs by spontaneous four-wave mixing
(SFWM) in photonic crystal optical fiber. We show that it is possible to engineer two-photon …

We propose a method of single photon detection of infrared (IR) photons at potentially
higher efficiencies and lower noise than allowed by traditional IR band avalanche …

This review covers recent theoretical and experimental efforts to extend the application of
the continuous-variable quantum technology of light beyond" Gaussian" quantum states …

We study both experimentally and theoretically the generation of photon pairs by
spontaneous four-wave mixing (SFWM) in standard birefringent optical fibers. The ability to …
