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.
