A 3D Monolithic Trap for Quantum Simulation and Computation

ORAL

Abstract

Quadrupole-based traps are versatile tools for AMO research and specifically for the ion-trapping community widely used in quantum computing, simulation, networks and sensing. Despite the advances of planar chip microfabricated traps, 3D blade traps still offer the advantages of ease of use , eV-deep trapping potentials, robustness to stray fields, larger ion-electrode distance (low heating rates), and wider and multi-directional optical access. A monolithic segmented blade trap represents further advancement in the blade trap design as it offers better structural accuracy by eliminating the need for manual alignment, a compact structure, a potentially more elaborate design, and better manufacturability and repeatability. Here we present the design of a compact, highly versatile monolithic blade trap manufactured by Translume Inc. With a new optimized design to reduce the capacitance, we demonstrate that we can drive the trap at >30 MHz at 1.6 kV pkpk without breakdown or damage. We characterize the thermal properties of the trap, the trapping potential uniformity, the residual micromotion and report heating rate measurements. Testing of the complete system, including the vacuum surrounding and the optical system, was independently performed on two separate assemblies at both Rice and Duke University. Our measurements show promising performance and support further development and implementations of this novel design, making ion-trapping easier and more affordable. Finally, we will discuss our individual addressing scheme for Raman beams to coherently manipulate long ion-chains, and optical schemes for coherent and incoherent electron shelving for partial measurements.
