Quantum Machines announced a median accuracy of 99.5% for two-qubit operations on Rigetti's commercial nine-qubit superconducting processor Novera, using its own control system.
The configuration was carried out through the OPX1000 platform and the QUAlibrate software, taking a total of 10 days for full calibration.
The median accuracy for single-qubit operations reached 99.93%. These metrics were achieved across all nine qubits and the 11 available connections between them.

In fact, the company demonstrated that a commercial processor can reach the claimed parameters without relying on the developer's proprietary infrastructure.
Rigetti confirmed that Novera can maintain high accuracy even when used with third-party control systems and software.
Novera is designed for local deployment and is built on the same architecture as Rigetti's larger superconducting systems. Users of solutions based on Novera include Fermilab, Montana State University, and Horizon Quantum.
It is worth noting that in May, developers from Quantus pointed out the cryptocurrency market's unpreparedness for quantum threats.
