Pasqal Achieves First On-Chip Neutral-Atom Qubit Trapping via Photonic Integrated Circuits - Quantum Computing Report

Neutral-atom quantum hardware developer Pasqal has achieved a technical milestone by trapping individual neutral atoms using laser light generated and routed directly through a Photonic Integrated Circuit (PIC). Developed in collaboration with its subsidiary Aeponyx—acquired less than 18 months prior—the demonstration replaces traditional free-space bulk optical tables with solid-state silicon nitride photonic chips, addressing a major physical scaling bottleneck in neutral-atom quantum computing architectures. In the proof-of-concept demonstration, Pasqal generated four optical micro-traps (optical tweezers) via a single photonic chip inside a quantum processing unit (QPU), successfully trapping and holding four individual rubidium atoms. The integrated photonic platform matched the trapping [...]
