- Rigetti Computing (RGTI, Financial) achieved a 99.5% median two-qubit gate fidelity on its new 36-qubit quantum system.
- The new system, composed of four 9-qubit chiplets, halved the error rate compared to the prior 84-qubit Ankaa-3 system.
- The company is on track to launch a 100+ qubit system with the same fidelity by the end of 2025.
Rigetti Computing, Inc. (RGTI) has reached an important technical milestone with its introduction of a 36-qubit quantum computer system, which has demonstrated an impressive 99.5% median two-qubit gate fidelity. This represents a twofold reduction in error rate from its previous best results on its 84-qubit Ankaa-3 system.
The new system utilizes a modular design comprising four 9-qubit chips, or chiplets, tiled together, which showcases Rigetti's proprietary technology. The company's approach addresses scalability challenges associated with building larger quantum systems.
Rigetti plans to officially launch the 36-qubit system on August 15, 2025. The company also remains on track to release a 100+ qubit chiplet-based system with the same level of fidelity by the end of 2025, marking a significant step toward advancing quantum computing technology.
CEO Dr. Subodh Kulkarni emphasized that Rigetti's superconducting qubits offer gate speeds 1,000 times faster than competing technologies such as ion traps and pure atoms, all while maintaining scalability advantages. This technological edge is seen as crucial for the development of larger quantum systems.
