IQM achieves 99.9% 2-qubit gate fidelity and 1 millisecond coherence time
• Qubit relaxation time of T1= 0.964 +- 0.092 milliseconds and dephasing time T2 echo 1.155 +- 0.188 milliseconds. • Two-qubit gates with a record fidelity reaching 99.9% • The results demonstrate that IQM’s in-house chip fabrication has reached quality on par with other world-leading institutions.
The results follow IQM´s recent benchmark announcements and indicate significant potential for further advancements on gate fidelities essential for fault-tolerant quantum computing and processors with higher qubit counts. The results were achieved through innovations in materials and fabrication technology and required top-notch performance across all components of the quantum computer, including QPU design, control optimisation, and system engineering. Hassel explained that the company is on track with its technology roadmap and is actively exploring potential use cases in machine learning, cybersecurity, route optimisation, quantum sensor simulation, chemistry, and pharmaceutical research.
