Quantum Photonics

(100 Word Limit): Quantum information science promises profoundly disruptive information and communication technologies. Photons are ideal carriers of quantum information: Their low noise, high speed transmission, and ease of manipulation at the single photon level make them indispensable for quantum communication, which offers security based on the laws of physics, quantum metrology, which promises the ultimate precision measurements, and quantum information processing, which promises exponentially greater computational power for particular tasks. Recently integrated optical devices have been applied to these technologies. We give an overview of quantum technologies and progress towards their realisation in integrated optics. Presenter Bio (100 Word Limit): O’Brien is director of the Centre for Quantum Photonics, University of Bristol. His Ph.D. from the University of New South Wales in 2002 was for experimental work on correlated and confined electrons in organic conductors, superconductors and semiconductor nanostructures, and progress towards silicon quantum computing. At the University of Queensland (2001-2006) he worked on quantum optics and quantum information science with photons. CQP’s efforts are focused on the fundamental and applied quantum mechanics at the heart of quantum information science and technology, from prototypes for scalable quantum computing to quantum communication, and quantum metrology.
