Quantum optics: Beyond single-photon counting
Abstract
Optical quantum information processing is at the frontier of modern physics and optics. It is a topic that relies heavily on manipulating single-photon states: exciting experimental applications, such as quantum cryptography, entanglement swapping and quantum-state teleportation, would be impossible without single-photon-counting detectors.
