IQM Quantum Computers Achieves Technological Milestones With 99.9% 2-Qubit Gate Fidelity And 1 Millisecond Coherence Time – The Quantum Insider
Insider Brief
IQM Quantum Computers, a global leader in building quantum computers, has reached significant milestones in superconducting quantum computing, demonstrating improvements in two key metrics characterising the quality of quantum computer.
A record low error rate for two-qubit operations was achieved by demonstrating a CZ gate between two qubits with (99.91 +- 0.02) % fidelity, which was validated by interleaved randomised benchmarking. Achieving high two-qubit gate fidelity is the most fundamental and hardest to achieve characteristic of a quantum processor, essential for generating entangled states between qubits and executing quantum algorithms.
Furthermore, qubit relaxation time T1 of 0.964 +- 0.092 milliseconds and dephasing time T2 echo of 1.155 +- 0.188 milliseconds was demonstrated on a planar transmon qubit on a silicon chip fabricated inIQMs own fabrication facilities. The coherence times, characterised by the relaxation time T1 and the dephasing time T2 echo, are among the key metrics for assessing the performance of a single qubit, as they indicate how long quantum information can be stored in a physical qubit.
These major results show that IQMs fabrication technology has matured and is ready to support the next generation of IQMs high-performance quantum processors. The results followIQMs recent benchmark announcementsand indicate significant potential for further advancements on gate fidelities essential for fault-tolerant quantum computing and processors with higher qubit counts.
The improvements in the two characteristics, two-qubit gate fidelity and coherence time, allow the quantum computer to be developed for more complex use cases. The significance of these results stems from the fact that only very few organisations have achieved comparable performance numbers before.
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.
This achievement cements our tech leadership in the industry. Our quantum processor quality is world-class, and these results show that we have a good opportunity of going beyond that,saidDr. Juha Hassel, theVice President of Engineering at IQM Quantum Computers.
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.
This announcement comes on the heels of the launch of Germanysfirst hybrid quantum computerat the Leibniz Supercomputing Centre in Munich, for which IQM led the integration with its 20-qubit quantum processing unit, and the opening of theIQM quantum data centrein Munich.

Think big: Computer the size of Suncorp Stadium to take shape near airport – Brisbane Times
According to the 2023 Queensland Quantum and Advanced Technologies Strategy, there will be 8700 jobs in quantum computing in Australia by 2030 in the fields of energy, decarbonisation, health and biotechnology, defence and aerospace.
The five universities are the University of Queensland, Griffith University, Queensland University of Technology, University of Southern Queensland and the University of the Sunshine Coast.
PsiQuantum, based in Palo Alto, California, was founded in 2016 by two UQ graduates, Jeremy OBrien and Terry Rudolph, while they worked at the University of Bristol.
A quantum computer is designed to solve complex problems in chemistry, maths and physics beyond the scope of conventional computers.
Quantum computers could revolutionise the development of drugs, materials and sustainable energy solutions, unlocking innovations that would otherwise remain unreachable.

UQ vice-chancellor Professor Deborah Terry said quantum physics impact on education would stretch from high schools into research.
Students starting high school this year will graduate into a world with utility-scale quantum computers, Terry said.
We will work with PsiQuantum across the education spectrum from schools, through TAFE, to universities to prepare our students for future jobs in quantum and advanced technologies.
Griffith Universitys vice-chancellor, Professor Carolyn Evans, said the consortium would be a new frontier for students.
