Optical quantum Information Processing makes use of the quantum mechanical properties of single photons to achieve useful information processing functions. This talk will present work carried out at the University of Southampton on the fabrication of optical waveguide device to realize essential functions for all optical quantum information handling. Utilizing silica-on-silicon as a platform and direct UV writing of waveguides, the talk will present results on key elements including single photon sources, waveguide circuits and waveguide sensors. The developing field of quantum information processing offers many highly desirable technical advantages over classical information technology. By exploiting the inherent quantum nature of fundamental particles, there is potential to develop disruptive new devices, for example offering unprecedented computing power (in Quantum Computing), approaches to guaranteed secure communications (based on quantum key distribution), as well as a host of new opportunities in precise measurement of time, gravity, magnetic field etc.. Many of these interesting quantum operations require the use of light, either to carry information between nodes, or for the operation of the device itself (e.g., an atom trap), or for carrying out the quantum processing itself. In this talk results on devices fabricated at the University of Southampton will be presented. Much of this work has been carried out collaboratively with colleagues from the University of Oxford and with NIST, Boulder, Co. In this talk the fabrication and device issues will be presented, together with examples of how these devices can be used to achieve such functions as quantum teleportation, quantum enhanced resolution enhancement, and Boson sampling.

Abstract

Optical quantum Information Processing makes use of the quantum mechanical properties of single photons to achieve useful information processing functions. This talk will present work carried out at the University of Southampton on the fabrication of optical waveguide device to realize essential functions for all optical quantum information handling. Utilizing silica-on-silicon as a platform and direct UV writing of waveguides, the talk will present results on key elements including single photon sources, waveguide circuits and waveguide sensors. The developing field of quantum information processing offers many highly desirable technical advantages over classical information technology. By exploiting the inherent quantum nature of fundamental particles, there is potential to develop disruptive new devices, for example offering unprecedented computing power (in Quantum Computing), approaches to guaranteed secure communications (based on quantum key distribution), as well as a host of new opportunities in precise measurement of time, gravity, magnetic field etc.. Many of these interesting quantum operations require the use of light, either to carry information between nodes, or for the operation of the device itself (e.g., an atom trap), or for carrying out the quantum processing itself. In this talk results on devices fabricated at the University of Southampton will be presented. Much of this work has been carried out collaboratively with colleagues from the University of Oxford and with NIST, Boulder, Co. In this talk the fabrication and device issues will be presented, together with examples of how these devices can be used to achieve such functions as quantum teleportation, quantum enhanced resolution enhancement, and Boson sampling.
