The brief
- Raised $300M in July 2026 and $475M in October 2026, $775M in total; valued around $5.5B after the second round.
- Its March 2026 paper with Caltech estimates Shor's algorithm could run on about 10,000 reconfigurable atomic qubits.
- Co-founder Manuel Endres's Caltech lab trapped a record 6,100-atom qubit array in 2025.
Technical approach
Single atoms held by laser tweezers
Each qubit is one neutral atom held by a focused laser beam in vacuum. Thousands of identical atoms fit in one chamber, so scaling beats wiring chips.
Rearrange qubits during a computation
Atoms can be shuttled across the array mid-calculation, so any qubit can sit next to any other. Dense error-correcting codes need that flexible wiring.
High-rate error correction
Instead of surface codes (about 4% of atoms do useful work), it uses codes that pack many logical qubits into few atoms: about 30% in its paper.
