Successful AI-powered calibration of a Rigetti QPU
AI-powered tools from Quantum Elements and Qruise remotely automated the calibration of a Rigetti QPU integrated with Quantum Machines’ control system. This work was part of the “AI for Quantum Calibration Challenge” (the “Challenge”) hosted at the Israeli Quantum Computing Center. The two companies participating in the Challenge, Quantum Elements and Qruise, automated the calibration of a 9-qubit Rigetti Novera™ QPU integrated with Quantum Machines’ advanced OPX1000 control system and NVIDIA DGX Quantum, a unified system for quantum-classical computing that NVIDIA built with Quantum Machines. This achievement showcases the potential of AI in quantum computer calibration and also highlights the growing collaboration within the quantum computing ecosystem.
Quantum Elements, Cruise, and Quantum Machines are members of Rigetti's Novera QPU Partner Program -- an ecosystem of quantum computing hardware, software, and service providers who build and offer integral components of a functional quantum computing system.
“We believe that another advantage we leverage is our modular approach to developing our technology. By enabling our partners to integrate their technology with ours, we can explore and advance creative and flexible ways to improve quantum computing capabilities,” says Dr. Kulkarni.
Research demonstrating optical reading technique published in Nature Physics
Joint research with QphoX and Qblox demonstrating the ability to readout superconducting qubits with an optical transducer was recently published in Nature Physics. This approach to qubit signal processing could have benefits in building scalable quantum computers as it could be a more compact, modular approach for measuring qubit performance in quantum computing systems that rely on microwave amplification. Current qubit readout techniques used by superconducting quantum computer systems in cryogenic environments can be resource intensive from a thermal and power usage perspective. A potential solution to this problem may be to replace coaxial cables and other cryogenic components with optical fibers, which have a considerably smaller footprint and negligible thermal conductivity. To demonstrate the potential of this technology, QphoX, Rigetti and Qblox connected a transducer to a superconducting qubit, with the goal of measuring its state using light transmitted through an optical fiber. It was discovered that the transducer is capable of converting the signal that reads out the qubit and the qubit can also be sufficiently protected from decoherence introduced by thermal noise or stray optical photons from the transducer during operation.
Conference Call and Webcast
Rigetti will host a conference call later today, March 5, 2025, at 5:00 pm ET, or 2:00 pm PT, to discuss its fourth quarter and full-year 2024 financial results.
You can listen to a live audio webcast of the conference call at https://edge.media-server.com/mmc/p/5jaikwa8/ or the "Events & Presentations" section of the Company's Investor Relations website at https://investors.rigetti.com/. A replay of the conference call will be available at the same locations following the conclusion of the call for one year.

About Rigetti
Rigetti is a pioneer in full-stack quantum computing. The Company has operated quantum computers over the cloud since 2017 and serves global enterprise, government, and research clients through its Rigetti Quantum Cloud Services platform. In 2021, Rigetti began selling on-premises quantum computing systems with qubit counts between 24 and 84 qubits, supporting national laboratories and quantum computing centers. Rigetti’s 9-qubit Novera QPU was introduced in 2023 supporting a broader R&D community with a high-performance, on-premises QPU designed to plug into a customer’s existing cryogenic and control systems. The Company’s proprietary quantum-classical infrastructure provides high-performance integration with public and private clouds for practical quantum computing. Rigetti has developed the industry’s first multi-chip quantum processor for scalable quantum computing systems. The Company designs and manufactures its chips in-house at Fab-1, the industry’s first dedicated and integrated quantum device manufacturing facility. Learn more at https://www.rigetti.com/.
