Sensing Technology & Novel Color Centers


To push sensing technology to new limits it is not enough to rely only on already proven and established mechanisms; we constantly aim to improve our existing toolbox as well as finding new ways of implementing quantum high tech to tackle existing scientific challenges and open questions in fundamental physics. Our efforts in this endeavor include devising new fabrication techniques [1] [2] crystallographic deliberation [3], and efficient microwave delivery, as well as detailed defect center characterization, be it in their fundamental quantum properties [4] or as to their exact location in the sample. We also study novel color centers (such as the silicon vacancy in diamond) and their sensing capabilities for applications where the NV center might prove less suitable.
