Rigetti Computing

A great way to end the week! Proud of the QM team for achieving 99.5% median two-qubit gate fidelity across all 11 couplings and 99.93% median single-qubit fidelity across all 9 qubits on Rigetti's commercially available #Novera™ QPU - using QM's OPX1000 and QUAlibrate platform and bringing the system up in just 7 days. More importantly, the results demonstrate that high-performance operation can be reproduced outside the original hardware developer's environment - a key step toward scalable quantum computing. Congratulations to the team!! 🎉 Technical details: [https://lnkd.in/gMvU7QHE) #QuantumComputing | #SuperconductingQubits | #QuantumInfrastructure | #Rigetti | #QuantumMachines | Rigetti Computing

Thanks to advances in quantum computing technology, including error mitigation techniques, we are seeing increasingly more meaningful quantum applications coming to bear. The Rigetti team, in collaboration with Lawrence Livermore National Laboratory and the University of Colorado Boulder, recently discovered an exciting method for simulating plasma waves using our 84-qubit Ankaa-3 system. Accurately simulating plasma has long been a challenge for classical computers, but as this work demonstrates, we are exploring innovative ways to leverage current, noisy quantum systems that make this possible. The team built and ran a quantum “spin” model that captures the essential physics of waves in a plasma, to simulate electromagnetic waves scattering through a plasma. As expected, there were errors that obscured the outputs from the QPU, so the team developed novel variations of two complementary error mitigation techniques that enabled us to recover meaningful results from the experiment and successfully simulate the scattering of electromagnetic waves from inhomogeneous plasmas. This work demonstrates how we can use today’s quantum computers and error mitigation techniques to advance our understanding of plasma physics, and creates a framework for other applications where classical simulation is out of reach. 🔗 Learn more in our blog post: https://lnkd.in/e6jDn5K6 🔗 Read the full technical paper: https://lnkd.in/eAtgQGUm

A milestone for the #quantum computing ecosystem!! Using QM's Orchestration Platform with its #OPX1000 and #QUAlibrate calibration framework, our team calibrated and operated Rigetti's commercially available #Novera™ #QPU, achieving 99.5% median two-qubit gate fidelity across all 11 couplings and 99.93% median single-qubit fidelity across all 9 qubits — all within 7 days! In other words, we achieved consistently low error rates across the entire processor - not just isolated high-performance qubits. This matters because above 99% fidelity, even small improvements can significantly increase the size and complexity of quantum computations that can be run before errors overwhelm the result. The result represents what we believe to be the highest full-system Novera™ performance achieved to date between Rigetti Computing and a partner control systems company. 🎉 𝐑𝐞𝐚𝐝 𝐭𝐡𝐞 𝐟𝐮𝐥𝐥 𝐫𝐞𝐥𝐞𝐚𝐬𝐞 𝐡𝐞𝐫𝐞: https://hubs.la/Q04h_skd0 As quantum computing moves from isolated demonstrations to broad deployment across research institutions, national labs, and enterprises, the ability to reliably operate complex systems anywhere becomes increasingly important. This is a crucial step towards scaling. Congratulations to the team and our partners at Rigetti on this achievement!!! 💥🚀 𝐈𝐟 𝐲𝐨𝐮 𝐰𝐚𝐧𝐭 𝐦𝐨𝐫𝐞 𝐝𝐞𝐭𝐚𝐢𝐥𝐬 𝐨𝐧 𝐭𝐡𝐞 𝐞𝐱𝐩𝐞𝐫𝐢𝐦𝐞𝐧𝐭, 𝐫𝐞𝐚𝐝 𝐨𝐮𝐫 𝐭��𝐜𝐡𝐧𝐢𝐜𝐚𝐥 𝐝𝐞𝐞𝐩 𝐝𝐢𝐯𝐞 𝐡𝐞𝐫𝐞: https://hubs.la/Q04h_gNG0 𝐏𝐋𝐔𝐒 𝐝𝐨𝐧'𝐭 𝐦𝐢𝐬𝐬 𝐭𝐨𝐝𝐚𝐲'𝐬 𝐐𝐌 𝐬𝐞𝐦𝐢𝐧𝐚𝐫, 𝐩𝐫𝐞𝐬𝐞𝐧𝐭𝐞𝐝 𝐛𝐲 𝐑𝐢𝐠𝐞𝐭𝐭𝐢'𝐬 𝐒𝐕𝐏 𝐨𝐟 𝐐𝐮𝐚𝐧𝐭𝐮𝐦 𝐒𝐲𝐬𝐭𝐞𝐦𝐬, Andrew Bestwick!

Today President Trump’s administration, the U.S. Department of Commerce and Secretary Lutnick announced the signing of 9 letters of intent to provide $2.013 billion in federal incentives under the CHIPS and Science Act in the quantum computing and first quantum chip foundaries sectors. These funds will support a portfolio of quantum companies, including two domestic quantum foundry companies and 7 quantum computing companies to accelerate solving the most critical technology challenges in the race to develop utility scale, fault-tolerant quantum computers. The announcement will create the first two commercial quantum foundries (with GlobalFoundries and IBM ) to help establish and accelerate foundational domestic manufacturing capacity for the quantum sector. And the seven quantum computing transactions are a portfolio approach to strengthen and accelerate U.S. leadership across multiple quantum modalities. These qubit modalities including neutral atom, silicon-spin, superconducting, photonic, and trapped ion and accelerate R&D for the most consequential unresolved engineering problems including device reproducibility, optical complexity, error rates, cryogenic systems integration, control hardware, ultra-fast readout electronics, photonic loss, and interconnects. This announcement alone is over 2x the total investment made by the President in his first administration under the National Quantum Initiative Act in 2018. The Department will receive a minority, non-controlling equity stake in each company as a condition for receiving the funds to enhance the return for the U.S. taxpayer. Continued and Accelerating American leadership in frontier technologies. Infleqtion Diraq Rigetti Computing Quantinuum Atom Computing PsiQuantum D-Wave https://lnkd.in/eq_UkBF4

We are excited to announce that we’ve signed a letter of intent with the U.S. Department of Commerce for an award of up to $100 million in funding over three years to accelerate superconducting quantum computing R&D. The funding is allocated under the CHIPS Research and Development Office Broad Agency Announcement pursuant to the CHIPS Act to grow U.S. leadership in emerging technologies, including quantum computing. As our CEO, Dr. Subodh Kulkarni, noted in our announcement: “Quantum computing will have far reaching impacts on our nation’s national security, economic interests, and overall prosperity. We are honored that the U.S. government is seeking to partner with Rigetti to accelerate the pace of quantum computing commercialization and to bolster U.S. leadership in this revolutionary field. This investment will allow us to tackle key scaling bottlenecks more rapidly and get us closer to utility-scale quantum computing.” Learn more: https://lnkd.in/eWGg2ic3

108 qubits, live today on qBraid Lab! 🚀 Rigetti Computing's Cepheus-1-108Q is now in the device list. Twelve 9-qubit chiplets running as a single 108-qubit processor, direct integration, no separate cloud account. Performance Rigetti Computing is reporting: 99.1% median two qubit gate fidelity 99.9% median single qubit gate fidelity ~60 ns gates CZ as a native gate, which keeps QEC circuits shorter If you've been running on Ankaa-3, your circuits will port over. Same QCS backend, same gate set. The connectivity graph is different though, so anything tightly tuned to Ankaa-3's topology is worth a second look. Ping us if you want help! https://lnkd.in/gTxciZ_A
