- In March, the company revealed a long-sought solution to the “wiring problem,” demonstrating that the quantum charge-coupled device (QCCD) architecture can scale to large qubit numbers.
- Quantinuum’s H-Series became the first to achieve “three 9s” – 99.9% – two-qubit gate fidelity across all qubit pairs in a production device, a critical milestone enabling fault-tolerance.
- Then, in collaboration with Microsoft, Quantinuum ’s H2-1 was declared the first – and so far the only – quantum computer capable of achieving Level 2 Resilient quantum computing, creating four reliable logical qubits using error correction and detection to achieve an 800-fold reduction in error rate.
