Advanced Monolithic 3D ion trap for Quantum Sensing and Information Processing

We are proposing to design and fabricate an advanced monolithic 3D blade trap, which will be much more powerful and more stable than typical blade traps. Our design will incorporate features that will radically improve the trap operational capabilities over today’s standards. The trapping zone will be cut up into spatially distinctive sections, each of which will be optimized for performing a specific task. This will provide a capability that, so far, has been offered only by a few surface traps. Furthermore, unlike surface traps, our 3D design will offer advantages such as low heating rates, very efficient screening from stray electric fields, deep trapping potentials, and broad optical access. Our design will also include a means to efficiently dissipate heat, as required for stable trapping fields and reliable entangling operations. It will include a mechanism to control the trap frequency, which otherwise drifts as a result of unwanted fluctuations of the rf voltage, and it will incorporate some optical functionalities including laser beam application, and/or photon collection for state detection or remote entanglement. This trap, being monolithic, will require no assembly and it will fulfill the required micron-tolerances in positions of the different charge-carrying elements in all three dimensions across the entirety of the structure. This monolithic approach completely eliminates the severe internal alignment issues associated with all traditional (i.e. hand-assembled) blade traps.
