Electron spins bound to diamond defects can be controlled and measured using light – an amazing property that is key to their use in many quantum technologies. However, they have their limits, and sometimes go “dark”, becoming unresponsive to optical measurements. Researchers know how to avoid and work around this problem, but its physical mechanism…
A large group – a slew? a raft? – of graduate students have completed their degrees since the last update: Prasoon Shandilya defended his PhD in April 2023 and was immediately teleported to Vancouver where he joined Photonic Inc.’s growing quantum computing team. Masters students Peyman Parsa, Blaine McLaughlin, Parisa Behjat, and Xinyuan Ma have…
The lab’s latest work in Optics Express on creating a new type of diamond optomechanical resonator for coupling phonons to spins has been selected as an Editor’s Pick. Congratulations to Prasoon and Xinyuan!
Lab members teamed up to write a comprehensive review of progress in diamond quantum nanophotonics and optomechanics. Published in the IEEE Journal of Lightwave Technology, it is one of the journal’s most downloaded articles.
Congratulations to Blaine for submitting his tour-de-force study of nonlinear optical effects in gallium phosphide microcavities. These devices convert light from telecom to visible wavelengths with high efficiency and have future applications in quantum optics. Read the paper here
Congratulations to Anustup and Blaine for successfully defending their MSc thesis. We are looking forward to watching what they get up to next!
The Barclay lab is recruiting undergraduate students and prospective PhD candidates seeking to do research in quantum nanophotonics. We are also seeking postdoctoral researchers with expertise in nanofabrication. If you are interested, please email a brief description of your research interests to Paul, and include a copy of your CV and transcript. Previous nanophotonics experience…
Nature Physics published a great summary of our lab’s recent spin-optomechanical interface research. Check it out here.
Welcome to three new lab members: Peyman, who joins us from Tehran, Waleed, who arrives from Queens (where he worked in Stephen Hughes’ quantum photonics theory group), and Natalia, who comes from Campinas (Brazil) with a wealth of optomechanics expertise. Excuse the photo of our alumni. Photos of our new team members are incoming.
Optomechanical control of quantum memory The lab recently reported using vibrations in a nanoscale mechanical resonator to control (change the state) of a quantum memory. Crucially, this was accomplished using a device in which the mechanical vibrations were controlled with light, i.e. optomechanically. This is a milestone result in the lab’s quest to coupling single…
