Development of Fiber-based Entangled Photon Pairs Sources

Quantum entanglement is a fundamental resource in quantum applications. Optical fiber lays the foundations of infrastructure in metropolitan telecommunication system nowadays. The union of these two might lead to the next generation of practical quantum technology. Periodically poled silica fiber (PPSF) has been demonstrated to be ideal candidate as a source of polarization entangled photon pairs. A PPSF-based entangled photon pairs source is highly robust, compact, and compatible with the existing fiber network, thus it is crucial to the implementation practical quantum communication, sensing and computing. This project aims at further development on the PPSF-based entangled photon sources. By combining the knowledge of making PPSF from University of Southampton and the quantum specialty from University of Toronto, I plan to investigate the fabrication of PPSF that is able to generate ultrabroadband entangled photons and apply it to practical fiber quantum sensing and quantum communication. This project will contribute to the construction of quantum network in Canada.
