Neutral-atom contender deeply embedded with Microsoft; jointly set the 24-logical-qubit record.

Neutral-atom contender deeply embedded with Microsoft; jointly set the 24-logical-qubit record.

— Ledger Desk · analyst thesis

Bull case

upside

24 entangled logical qubits with Microsoft is the largest logical-qubit entanglement to date. 1,180-qubit strontium array. Phoenix system integrated into Azure Quantum. Selected for DARPA QBI Stage B. Cisco MOU for distributed quantum networking (March 2026). Strong dark-horse for early fault tolerance demonstrations.

Bear case

downside

Total raised reported between $101M and $272M depending on source — capitalization is murky. No disclosed major Series C as of May 2026 despite peers raising mega-rounds. Microsoft partnership creates strategic dependency. Neutral-atom gate speeds remain slow.
