Pasqal Achieves On-Chip Qubit Control Milestone — Pasqal Holding SAS

Event summary

Pasqal trapped individual atoms using laser light generated by a photonic integrated circuit (PIC), a world-first in neutral-atom quantum computing.
The achievement was made within 18 months of acquiring Aeponyx, demonstrating scalable qubit control for future large-scale fault-tolerant quantum computing (FTQC).
The photonic-chip architecture aims to shrink the optical footprint of future processors by as much as 50 times, enabling large-scale manufacturing.
Pasqal generated four optical traps through a single photonic chip, holding four individual rubidium atoms with atom lifetimes of approximately 27.5 seconds.

The big picture

Pasqal's achievement in on-chip qubit control represents a significant step forward in the quest for scalable, fault-tolerant quantum computing. By moving critical optical functions onto a photonic chip, Pasqal addresses one of the primary engineering challenges in neutral-atom quantum computing, potentially setting a new industry standard. This development underscores the strategic importance of acquisitions like Aeponyx in driving technical and commercial advances in the quantum computing sector.
