IonQ launches Superion 256, a 256-qubit sixth-generation system open for orders

IonQ launched its Superion product line with the Superion 256, a 256-qubit sixth-generation trapped-ion computer that uses on-chip electronic qubit control instead of lasers. The chip was designed and made with SkyWater. Orders are open now, with customer deliveries planned for 2027, and IonQ said a 10,000-qubit-class generation is in development in parallel.

• Superion 256: 256 physical qubits, sixth generation, Electronic Qubit Control on the chip
• Orders open now; customer deliveries expected in 2027
• Chip design cycle cut from nine months to two; six tapeouts in the first half of 2026
• IonQ says the system fits a standard server rack and draws less power than a rack of GPUs
• Commercial readiness targeted for 2028; these are company projections
