Engineering Novel Defects Centres in Diamond for Emerging Quantum Technologies


Dr Stefania Castelletto

Centre for Micro-Photonics, Swinburne University of Technology, Australia

3:30 pm Friday, 25 February 2011, EN101 Lecture Theatre (EN Building), Hawthorn.

Quantum technologies require new platforms and paradigms for their efficient fabrication and use. Single photon sources exemplify this need with their development pushing the bounds of existing materials and fabrication techniques. Color centres in diamond are a leading candidate for single photon generation, nd optical-spin readout, provided a suitable fabrication method can be identified.   
In this presentation, Stefania will review her recent work on fabrication, and characterization of novel point defects in diamond material, that could surpass the most known nitrogen-vacancy centers for application in emerging quantum technologies, such as quantum communication and quantum metrology.  She will present a comprehensive study of the recently discovered ultra bright Chromium in diamond color centres produced by ion implantation and chemical vapor deposition. She will highlight future directions to optimize these sources and determine the local chemistry by employing co-implantation techniques.
She will also present a brief review on the motivations leading to recent research in diamond color centers, particularly in the domain of super-resolution imaging and optical spin manipulation.
