High-fidelity trapped-ion qubit operations with scalable photonic modulators

ORAL

Abstract

Quantum information processors and atomic clocks based on trapped ions continue to scale towards greater I/O, size, and power requirements. These demands motivate the replacement of external optical conditioning elements, such as amplitude, phase, and frequency modulators, with integrated versions on the same chip. Here we present the design, fabrication, and implementation of a monolithically integrated piezo-optomechanical Mach-Zehnder modulator compatible with microfabricated surface ion traps[1-3]. We demonstrate quantum operations with these modulators, testing directly on a trapped ion apparatus, measuring single qubit gate fidelities better that 99.7%
