We review the current status of single-photon-source and single-photon-detector
technologies operating at wavelengths from the ultraviolet to the infrared. We discuss …

The past decade has seen a dramatic increase in interest in new single-photon detector
technologies. A major cause of this trend has undoubtedly been the push towards optical …

Growing interest in quantum computing for practical applications has led to a surge in the
availability of programmable machines for executing quantum algorithms,. Present-day …

Quantum key distribution (QKD) is the first quantum information task to reach the level of
mature technology, already fit for commercialization. It aims at the creation of a secret key …

Linear optics with photon counting is a prominent candidate for practical quantum
computing. The protocol by Knill, Laflamme, and Milburn [2001, Nature (London) 409, 46] …

Multiphoton interference reveals strictly nonclassical phenomena. Its applications range
from fundamental tests of quantum mechanics to photonic quantum information processing …

Single-photon detectors (SPDs) are the most sensitive instruments for light detection. In the
near-infrared range, SPDs based on III–V compound semiconductor avalanche photodiodes …

Single-photon detectors operating at visible and near-infrared wavelengths with high
detection efficiency and low noise are a requirement for many quantum-information …

Integration of superconducting nanowire single-photon detectors with nanophotonic
waveguides is a key technological step that enables a broad range of classical and quantum …

We propose a quantum repeater protocol which builds on the well-known Duan-Lukin-Cirac-
Zoller (DLCZ) protocol [LM Duan, MD Lukin, JI Cirac, and P. Zoller, Nature (London) 414 …
