Rigetti Computing Delays 108-Qubit System Availability to Optimize Performance

summarizeSummary

Rigetti Computing is delaying the general availability of its 108-qubit quantum computing system to optimize performance, while also reporting strong two-qubit gate fidelities on its systems.

check_boxKey Events

• 108-Qubit System Delay

  Rigetti Computing is revising its roadmap, delaying the general availability of its 108-qubit quantum computing system, Cepheus-1-108Q, to around the end of the first quarter of 2026.

• Reason for Delay

  The delay is due to the need for more time to test and optimize the system, specifically citing complexities with tunable couplers and the decision to run another iteration of the chip to improve fidelity.

• Achieved Gate Fidelities

  The company reported achieving a median two-qubit gate fidelity of 99% on its 108-qubit system, 99.7% on its 9-qubit system, and 99.6% on its 36-qubit system.

auto_awesomeAnalysis

Rigetti Computing announced a delay in the general availability of its flagship 108-qubit quantum computing system, Cepheus-1-108Q, pushing it to the end of the first quarter of 2026. This delay, attributed to complexities with tunable couplers and the need for further optimization, represents a setback in the company's product roadmap and could impact investor expectations regarding its competitive timeline in the quantum computing space. While the company also reported strong two-qubit gate fidelities across its systems, the delay of a key product is the more significant market-moving event, suggesting ongoing technical challenges in scaling quantum hardware.
