Quantinuum’s H2 quantum computer achieved a record Quantum Volume (QV) of 8,388,608, fulfilling its five-year goal of tenfold QV growth annually
QV, introduced by IBM, is a comprehensive metric combining qubit count, fidelity, connectivity, and error rates to benchmark quantum system performance
The H2-1 upgrade expanded the H2 system from 32 to 56 trapped-ion qubits, making classical emulation impractical for the new processor
Quantinuum emphasizes qubit quality over quantity, focusing on fault tolerance and commercial quantum computing readiness
Microsoft Azure Quantum is collaborating with Quantinuum to develop more logical qubits with lower error rates using the new 56-qubit H2-1
Quantinuum demonstrated the world’s first scalable, error-corrected, end-to-end quantum chemistry workflow using logical qubits and quantum phase estimation (QPE)
The chemistry workflow leverages H2’s scalable QCCD architecture, real-time QEC decoding, conditional logic, and all-to-all connectivity
