PERS CONFERENCE –
The official release of the H2 Quantinuum quantum processor, Powered by Honeywell, follows extensive pre-launch work with multiple global partners and is critical to the creation and controlled manipulation of anyone non-Abelian. Precise control of non-Abelian anyons has long been held up as a pathway to employing topological qubits for fault-tolerant quantum computers.
Tony Uttley, President and COO of Quantinuum, stated “With our second generation system, we are entering a new phase of quantum computing. H2 highlights the opportunity to achieve valuable results that are only possible with a quantum computer. The development of the H2 processor is also an important step in moving towards universal fault-tolerant quantum computing.”
He added, “This demonstration is a beautiful testament to the strength of our H-Series hardware roadmap and reinforces our core goal of enabling our customers to solve problems that were previously out of reach of classic computers. The implications for society are significant and we are excited to see how this technology truly changes the world.”
One of the first experiments conducted on H2 by scientists from Quantinuum, in collaboration with researchers from Harvard University and Caltech, demonstrated a new state of matter, a topologically non-Abelian ordered state. This is an area of expertise that has been pursued in “stealth mode” for several years within Quantinuum, with a core team based in Munich and led by Dr. Henrik Dreyer.
Due to the distinguishing features and precise control of the H2 processor, the topology states (which are essentially qubits with limited gate capacity) are engineered such that their properties can be precisely controlled in real-time, demonstrating the creation, braiding, and annihilation (measurement) of non-anyons. Abelian.
“Fault-tolerant quantum computing is our ultimate goal. Our world’s leadership in quantum computing continues to be showcased and proven by real progress, and the creation and manipulation of anyone non-Abelian to create topological qubits is another example that when extraordinary tools are given to brilliant people, they will find something extraordinary to use. done. with them,” said Ilyas Khan, Founder and Chief Product Officer at Quantinuum. “This could be the transistor moment for the quantum computing industry – and the fact that we have used a quantum computer as a machine tool to build a topological qubit that is a significant step towards fault-tolerant quantum computing is further evidence of our long-standing belief that the most powerful quantum systems both explored and created by other quantum systems. This is precisely what Feynman anticipated in his now famous remarks that are so often cited as the basis for quantum computing.”
He added, “We are looking forward to building on this important breakthrough. These are exciting times ahead for the entire industry and we have several further milestones that we can’t wait to share with the world.”
Innovation in H2
Initial H2 features include 32 fully connected high-fidelity qubits and a new architecture that advances the linear design of the H1 System Model (with a new ion trap whose oval shape resembles a “race track”). Quantinuum showcased H2’s capabilities by demonstrating its 32-qubit GHZ state (a non-classical state with all 32 qubits entangled globally), the largest on record.
The unique “racecourse” design of the H2 System Model enables all inter-qubit connectivity, meaning that each qubit in H2 can be directly linked in pairs with any other qubit in the system. Doing so in the near term reduces the overall error in the algorithm, and in the long term opens additional opportunities for new, more efficient error correcting codes – both critical to continuing to accelerate the power of quantum computing. When combined with the demonstration of controlled non-Abelian anyons, the integrated achievements highlight a critical step in topological quantum information storage and processing.
In addition, this new design is a strong step towards demonstrating the scalable potential of ion trap devices. H2 is not only a demonstration of the scaling power of ion traps in quantum charge coupled device (QCCD) architectures: demonstrating the ability to scale qubit numbers simultaneously while preserving performance, but also contains new technologies that pave the way for further scaling in the future. generation. Similar to first-generation systems, H2 is designed to accommodate future upgrades over its product lifecycle, meaning that both qubit number and qubit quality will improve.
Built on the proven H-Series Quantinuum foundation, the System Model H2, includes many distinctive features that collectively set it apart from other types of quantum computers: all-to-all connectivity, qubit reuse, intermediate circuit sizing with conditional logic, qubit operations industry-leading high fidelity, and long coherence times. In addition, System Model H1’s impressive performance gains to achieve record high Quantum Volume (QV) is expected to continue with H2. H2 launched with Quantum Volume 65,536 surpassing the last record announced using H1-1 in February this year.
Using H2 Today
In addition to major breakthroughs, H2 has been active in experimental studies by various organizations and companies, with notable results:
Global Technology Applied Research at JPMorgan Chase has published a scientific paper on the design of quantum optimization algorithms for portfolio optimization, with numerical results successfully validated on H2 during early access.
H2 is now available via cloud-based access from Quantinuum and will be available via Microsoft Azure Quantum starting in June. Additionally, a noise-informed H2 emulator is possible via NVIDIA’s cuQuantum SDK of optimized libraries and tools, which helps accelerate quantum computing simulation workflows.
Dr. Rajeeb (Raj) Hazra, CEO of Quantinuum said, “For anyone who thought that a quantum computer capable of pushing the limits of human knowledge and scientific progress is still far away, today marks a turning point. A team of world-leading scientists have used the H2 Quantinuum quantum computer to achieve something that was previously impossible.” He continued by commenting, “H2 provided a breakaway moment for Quantinuum. Our second-generation quantum computer powered by the H2 quantum processor and related software, delivers the industry’s best performance today, while laying the foundation for significantly accelerating the path of fault-tolerant quantum computing.”
