Abstract
An atom control architecture based on VIS-IR photonic integrated circuit (PIC) technology is characterized by (1) visible (VIS) and near-infrared (IR) wavelength operation, (2) channel counts extensible beyond 1000s of individually addressable atoms, (3) high intensity modulation extinction and (4) repeatability compatible with low gate errors, and (5) fast switching times. A 16-channel SiN-based APIC with (5.8±0.4) ns response times and <−30 dB extinction ratio at a wavelength of 780 nm. Based on a complementary metal-oxide-semiconductor (CMOS) fabrication process, this atom-control PIC (APIC) technology can be used for atomic, molecular, and optical physics and emerging applications, from quantum computers with cold atoms or ions to quantum networks with solid-state color centers. This APIC technology is especially suitable for scalable quantum information processing based on optically programmable atomic systems.
