Rigetti Computing demonstrates multi-chip quantum computer

Rigetti Computing (RGTI) has achieved its mid-year performance milestone of 99.5% median two-qubit gate* fidelity on its modular 36-qubit system, a 2x reduction in median two-qubit gate error rate from Rigetti’s previous best results on its 84-qubit single chip Ankaa-3 system. Composed of four 9-qubit chips (“chiplets”) tiled together, the 36-qubit system is based on Rigetti’s proprietary modular chip technology and unlocks the Company’s path to building a 100+ qubit chiplet-based system. Rigetti plans to launch its 36-qubit system on August 15, and remains on track to release its 100+ qubit chiplet-based system at 99.5% median two-qubit gate fidelity before the end of 2025.
