Rigetti Computing

Looking back on the summer, we’re still beaming from the energy and talent that interns brought to Rigetti as part of our 2024 Summer Internship Program. We received nearly 400 applications and ultimately selected 9 students to work on projects across our technology stack. Rigetti is on a mission to build the world’s most powerful computers to help solve humanity’s most important and pressing problems, and we can’t do that without looking ahead to the talent of the future. From working on quantum algorithms for optimization to cryogenic hardware development, our interns gained hands-on experience with our quantum computing systems and collaborated with teams across multiple scientific and engineering disciplines. As this year’s program closes, we asked students to share highlights of their time with us and a glimpse of life as a Rigetti intern!

In honor of American Indian Heritage Month, we are proud to share a profile of David Snow, Lead Mechanical Design Engineer at Rigetti, that was published in the Fall 2024 AISES Winds of Change Magazine. AISES is a national nonprofit organization focused on substantially increasing the representation of Indigenous peoples of North America and the Pacific Islands in STEM studies and careers. David is a member of the Lac du Flambeau Band of Lake Superior Chippewa Indians. He is an AISES Sequoyah Fellow and Treasurer for the AISES Northern California Professional Chapter. David held various student chapter positions during his time at @Montana State University (MSU) to help other Native students build a campus community, a role he continues to play today by supporting the AISES student Chapter at MSU. Check out the full profile to learn more about how David’s love of nature led him to designing hardware for superconducting quantum computers at Rigetti: https://lnkd.in/eTaq5r-e

Reaching fault tolerance, and in turn realizing the full potential of quantum computers, will require the co-development of quantum error correction and quantum computing technologies. We are excited to share our recent work with Riverlane demonstrating real-time and low-latency quantum error correction by integrating Riverlane’s quantum error decoder with our 84-qubit Ankaa™-2 system. Among the quantum error correction resources being developed are classical algorithms that identify errors that occur during quantum computation. These classical algorithms are known as decoders. A challenge in improving the utility of decoders is addressing the problem of the backlog of computations that accumulates as the decoder processes data. To avoid the backlog problem, the decoding needs to occur at the same speed as the quantum circuit. This experiment demonstrated decoding times faster than the 1\unit\micro threshold for generating measurement data on a superconducting qubit device -- ensuring that the backlog problem is avoided and showcasing that low-latency feedback can be maintained during quantum error correction operations. 🖇 You can read the full arXiv paper here: https://lnkd.in/eWKz_QVp And learn more in our press release: https://lnkd.in/e4mCsZvS 

Last week, the UK’s National Quantum Computing Centre (NQCC) officially opened the doors of its landmark facility on Harwell Campus. The facility will support world-class quantum computing research and provide state-of-the-art laboratories for designing, building, and testing quantum computers. Rigetti’s system located at the NQCC is a fully operational 24-qubit Ankaa™-class quantum computer, featuring tunable couplers and a square lattice for fast gate times, enhanced connectivity, and high fidelity. As part of the implementation, Rigetti will be integrating Riverlane’s technology with the long-term objective of large-scale error correction. We were honored to have Rigetti CEO Dr. Subodh Kulkarni and CTO David Rivas attend the inauguration. “The NQCC opening is a great occasion for both the UK and Rigetti. We are proud that Rigetti’s on-premises quantum computer is fully operational for the NQCC research team to pursue critical research to advance our understanding of how to use quantum computing to solve real-world problems,” says Dr. Kulkarni.

A quantum leap for Harwell. We're thrilled to announce the official opening of the National Quantum Computing Centre (NQCC) at Harwell, a pioneering facility that will propel advancements in healthcare, energy efficiency, and climate resilience. With support from UK Research and Innovation (UKRI), the NQCC is set to house 12 state-of-the-art quantum computers, a testament to the UK’s dedication to breakthrough technologies. The 4,000-square-metre, purpose-built centre stands as a beacon for innovation, uniting industry and academia to make quantum computing practically usable at scale. From accelerating drug discovery to optimising energy distribution, the possibilities are limitless. Our testbed companies and NQCC scientists are heading up the work at the centre, which is hoped, will speed up the development of quantum computing, including Aegiq, Infleqtion, ORCA Computing, Oxford Ionics, Quantum Motion, QuEra Computing Inc., Oxford Instruments plc, and Rigetti Computing, to name a few. Science minister Patrick Vallance says it best: “The National Quantum Computing Centre marks a vital step forward in the UK’s efforts to advance quantum technologies. By making its facilities available to users from across industry and academia, and with its focus on making quantum computers practically useable at scale, this Centre will help them solve some of the biggest challenges we face, whether it’s delivering advances in healthcare, enhancing energy efficiency, tackling climate change, or inventing new materials. The innovations that will emerge from the work the NQCC will do will ultimately improve lives across the country and ensure the UK seizes the economic benefits of its leadership in quantum technologies."

Quantum error correction (QEC) will be essential to achieve the accuracy needed for quantum computers to realize their full potential. Together with Riverlane, we are working to advance our understanding of how to build fault tolerant quantum computers using QEC technology. Our recent paper with Riverlane, “Demonstrating real-time and low-latency quantum error correction with superconducting qubits,” (https://lnkd.in/eWKz_QVp) describes the details of how we performed a QEC experiment in extremely low-latency hardware. By integrating a scalable FPGA decoder into the control system of a Rigetti QPU, we were able to achieve very low latencies, which were verified using feedback operations. This is an exciting step in our work to improve the accuracy of quantum computations.  Learn more about this work in Riverlane’s new blog post: https://lnkd.in/e8sf4bTi

We are excited to share that Rigetti CEO, Dr. Subodh Kulkarni, will be a speaker at the second annual Stanford Conference on Technology + National Security https://lnkd.in/eNTYn-kr. The conference is hosted by Stanford DEFCON, a student network under the purview of the Gordian Knot Center for National Security Innovation at Stanford University, and will be held October 8-9 at the Hoover Institution. Dr. Kulkarni will be speaking on the “R&D Ecosystem: Scaling Critical Technologies” panel at 11:15 AM on October 9 where he will discuss the role of quantum computing in national security, and how academia and the private sector can help to support the government to develop and deploy such critical technologies. “It’s an honor to be included in this premier conference to discuss how quantum computing can help tackle national security challenges,” said Dr. Subodh Kulkarni, Rigetti CEO. “At Rigetti, we strongly believe that quantum computing will have a profound impact on many areas in society, especially national security. Superconducting promises to be the leading modality for building the large-scale, high-performance quantum computing systems necessary for tackling the complex problems that are currently untenable with even the most powerful classical computers. Our next-generation Ankaa™-class systems are performing in the 99 - 99.5% range for 2-qubit fidelity. Our gate speeds have an active duration of 60-80ns, making our systems twice as fast as other superconducting quantum computing players, and 3-4 orders of magnitude faster than trapped ion and pure atom quantum computing systems.” Rigetti remains on track to deploy its anticipated 84-qubit Ankaa-3 system with the goal of achieving a 99+% median 2-qubit gate fidelity by the end of 2024. Rigetti’s 9-qubit Novera™ QPU, based on the Company’s Ankaa-class architecture, is available today for on-premises quantum computing systems.
