A Dielectric Antenna for Quantum Emitter Interfaces

ORAL

Abstract

Color centers in diamond have shown long spin coherence time and stable optical properties as a promising system for large scale quantum information processing. Collecting single photons from emitters with high efficiency can significantly boost the entanglement generation rate of remote quantum memories. Here, we propose a method to design a dielectric antenna for low numerical aperture optics systematically. Our simulation results show that the design is robust in the presence of fabrication imperfection. The dielectric antenna design enables efficient interfaces to closely packed arrays of quantum memories for multiplexed quantum repeaters, arrayed quantum sensors, and modular quantum computers.
