Rigetti Computing, Inc. (Nasdaq: RGTI) has achieved its mid-year performance milestone of 99.5% median two-qubit gate fidelity on its modular 36-qubit system. This represents a 2x reduction in median two-qubit gate error rate compared to Rigetti’s previous results on its 84-qubit single-chip Ankaa™-3 system. The 36-qubit system is composed of four 9-qubit chiplets tiled together, utilizing Rigetti’s proprietary modular chip technology. The modular chip technology is intended to support Rigetti’s path to building higher qubit count systems.

Rigetti implements CZ gates, which are computationally equivalent to iSWAP gates, for executing quantum circuits. The company aims to leverage techniques from the semiconductor industry to enable the scaling of its superconducting qubit systems. Rigetti operates quantum computers over the cloud and provides on-premises quantum computing systems, designing and manufacturing its chips at Fab-1. The achievement of this gate fidelity milestone on the modular system is positioned as a step towards Rigetti’s goal of developing larger qubit count systems. Rigetti plans to launch its 36-qubit system on August 15, 2025. The company also remains on track to release its 100+ qubit chiplet-based system, targeting 99.5% median two-qubit gate fidelity, before the end of 2025.

In contrast to its previously best 84 qubit Ankaa 3 single-chip platform, quantum computing startup Rigetti Computing, Inc. announced today that its modular 36 qubit superconducting quantum system has achieved a remarkable milestone: 99.5 % median two qubit gate fidelity, effectively halving its error rate. This discovery opens the door for more dependable and scalable quantum systems and marks a major advancement in the race towards fault-tolerant quantum computing. Rigetti used a modular architecture instead of a big monolithic device, joining four 9 qubit “chiplets” to create a 36 qubit system.

This architecture has several advantages: Known as the biggest multi-chip quantum processor in the market to date, this system is a prime example of how modular quantum computing technologies, which are becoming popular in the business, are gaining popularity. CZ (controlled-Z) gates, a key two qubit operation, are essential to reaching the fidelity milestone. A median fidelity of 99.5 percent was reported by Rigetti Computing, which was twice as good as the greatest two qubit gate performance on the previous 84 qubit Ankaa 3 processor.
