Why Is Rigetti Computing Stock Gaining On Tuesday?

Rigetti Computing, Inc. RGTI shares are trading higher on Tuesday.

The company is making significant strides in the quantum computing field with its latest AI-powered calibration breakthrough.

In collaboration with Quantum Machines, Rigetti successfully applied artificial intelligence to automate the calibration of a 9-qubit Novera Quantum Processing Unit (QPU), achieving unprecedented accuracy and speed.

This achievement was part of the “AI for Quantum Calibration Challenge,” hosted at the Israeli Quantum Computing Center (IQCC), and marks a major milestone for the quantum computing ecosystem.

Two participating companies, Quantum Elements and Qruise, automated the calibration process, which is traditionally a highly complex and time-consuming task.

Using AI tools, Quantum Elements achieved 99.9% single-qubit gate fidelity and 98.5% two-qubit gate fidelity. Qruise fine-tuned all nine qubits simultaneously, significantly accelerating the setup process.

This achievement builds on Quantum Machines’ collaboration with NVIDIA Corporation to apply AI in quantum computing. In September, they used reinforcement learning with the NVIDIA DGX Quantum platform to optimize a control pulse for a Rigetti QPU in real-time.

As quantum systems scale up, calibration becomes one of the biggest challenges, with qubit interactions and parameter drifts complicating the process.

Yonatan Cohen, CTO of Quantum Machines, emphasized that traditional manual calibration would not be feasible for larger systems with thousands of qubits.

The success of AI-powered calibration could remove this bottleneck, allowing for faster and more efficient scaling of quantum systems.

Rigetti’s CTO, David Rivas, noted that AI tools had achieved performance levels that would otherwise require weeks of “manual” engineering work.

“As we advance toward larger qubit counts, having validated that AI tools can reach our performance benchmarks is an exciting moment for the industry. This successful demonstration shows how automation accelerates quantum computer setup while maintaining the exacting standards required for quantum computation,” Rivas added.

Price Action: RGTI shares are trading higher by 24.7% to $5.575 at last check Tuesday.
