Pasqal Uses Photonic Chip to Trap Individual Atoms for Neutral-Atom Quantum Computing
Pasqal demonstrated trapping of individual neutral atoms using a photonic chip, replacing bulk optics with integrated waveguides. This approach could miniaturize optical tweezer arrays for neutral-atom quantum computing. The work advances scalable, manufacturable quantum processor architectures.

This could enable scaling of neutral-atom systems to thousands of qubits in a compact, manufacturable format, moving beyond laboratory optics.
Photonic chips can be mass-produced using semiconductor fabrication, and integrating the trapping optics on-chip removes alignment challenges and reduces footprint. If the chip-based traps preserve atomic coherence and can be extended to full 2D arrays, it paves the way for commercial-scale processors.
