Quantinuum achieves 99.9% two-qubit gate fidelity; surpasses 1 million QV

Product updates

  • US-based full-stack quantum computing company Quantinuum unveiled that its 20-qubit quantum processor H1-1 achieved the “three 9's,” a 99.9% two-qubit gate fidelity in a commercial quantum computer, marking the first in the industry to do so. The company also reported that it surpassed a quantum volume (QV) of 1 million, the highest thus far.

  • The company also demonstrated its quantum charge-coupled device (QCCD) architecture, which solves the longstanding wiring problem in quantum computing, in March 2024.

  • Analyst QuickTake : Achieving 99.9% two-qubit gate fidelity indicates the computer’s greatly advanced error correction capabilities, which can increase the reliability of quantum computations. This progress marks a pivotal moment for the quantum computing industry as it gets closer to the breakeven point of logical qubits outperforming physical qubits, thereby enabling efficient real-life computational solutions.
