# Photonic quantum information processing: A concise review

@article{Slussarenko2019PhotonicQI, title={Photonic quantum information processing: A concise review}, author={Sergei Slussarenko and Geoff J. Pryde}, journal={Applied Physics Reviews}, year={2019} }

Photons have been a flagship system for studying quantum mechanics, advancing quantum information science, and developing quantum technologies. Quantum entanglement, teleportation, quantum key distribution and early quantum computing demonstrations were pioneered in this technology because photons represent a naturally mobile and low-noise system with quantum-limited detection readily available. The quantum states of individual photons can be manipulated with very high precision using…
