Overview

• Rigetti’s four-chiplet, 36-qubit system hit a 99.5% median two-qubit gate fidelity, representing a twofold reduction in error rates from its prior best results.
• The demonstration marks the largest multi-chip quantum computer to date, showcasing a scalable approach to higher qubit counts.
• Rigetti plans to publicly launch the 36-qubit platform on August 15 and aims to deploy a 100+ qubit chiplet-based system by year-end 2025.
• Shares of Rigetti Computing surged more than 30% to about $16.56 following the performance announcement.
• CEO Subodh Kulkarni highlighted superconducting qubits’ gate speeds as over 1,000 times faster than competing modalities as a key competitive edge.
