Surface-Electrode Trap to Control Levitating Nano-diamonds — •Deviprasath Palani, Oleg Orlov, Tobias Schaetz, and Ulrich Warring — Albert-Ludwigs-Universität Freiburg, Physikalisches Institut, Hermann-Herder-Strasse 3, 79104 Freiburg, Germany
Physical properties of crystal defects, e.g., nitrogen-vacancy (NV) centers, in synthetic diamonds are intensively studied, as they rise the promise for several applications within the fields of physics, nanotechnology, and life science [1]. As the quantum nature (coherence) of NV centers is well protected by the surrounding diamond lattice, it can be harnessed even under ambient conditions. To use these defects as nanoscale sensors, they are packed into diamond crystallites of a few tens of nanometers in diameter comprised of about 109 carbon atoms. But to harness their full potential, suitable techniques are required to control their spatial position and orientation, as well as, to efficiently manipulate their quantum state. In our presentation, we introduce details of a compact and robust experimental setup that builds on a so-called surface-electrode trap [2], originally developed for trapping individual atoms [2]. Our setup integrates components necessary to control all degrees of freedom(as mentioned above) in a commercially fabricated printed circuit board. We present preliminary benchmark results and discuss application prospects. [1] Schirhagl, R. et al., Annual Review of Physical Chemistry. 2014 Apr;65(1):83*105. [2] Seidelin, S. et al., Phys. Rev.
