Why IQM Radiance™?

Assessing the hardware performance of quantum computers relies on several characteristics, which have to be well balanced to allow maximum usefulness for applications and algorithms. Superconducting technology performs exceptionally well across all dimensions. That’s why VTT, LRZ and others decided to integrate our system:


Quantum algorithms rely on high-quality two-qubit gates for computational advantages, but stray coupling ("crosstalk") can degrade gate quality. IQM's quantum computers address this with tunable coupler technology based on transmons, enabling full idling of interaction, minimizing errors and enabling fast gates (20 ns – 40 ns). Although tunable couplers increase the effective number of qubits on the QPU by a factor of 2-3 times, IQM has successfully implemented this technology to maintain exceptional QPU quality. IQM achieves high fidelity even in large QPUs with extremely fast gate execution.


With 20 and 54 high-fidelity computational qubits, significant advances are foreseen in the field of executing quantum algorithms from optimization, simulation, and quantum machine learning for several application domains, such as life sciences, chemistry, or industrials. With 150 qubit IQM Radiance, end users will be able to discover new science and push to the frontier of quantum utility on the hardest computational problems, as this is far beyond the number of qubits that can be simulated on classical hardware.


We are committed to delivering best-in-class fidelity with our quantum systems to enable usability. With IQM Radiance 20, you can access the full range of qubits for your quantum research. We achieve this through high-quality qubits with industry-leading fidelities, enabling us to execute many steps of quantum circuits and to fully entangle qubits. This makes our superconducting qubits highly useful for quantum algorithms.


Even though the lifetime of superconducting qubits is not very high, our extremely fast gates last 1/1000 of the qubit lifetimes, enabling deep algorithm executions. The Circuit Layer Operations per Second (CLOPS) are much higher than in other qubit technologies, which removes the bottleneck in the effective integration of our quantum systems with classical computers in so-called hybrid environments, to executive variational algorithms.


Our QPUs are based on full square grid topology to enable high parallelization together with short distances across the chip and consequently improved algorithm performance. This is favorable to reach a high level of entanglement, and sub-patches of qubits can be defined with high flexibility. This allows Radiance to define optimal clusters for calculation on a large QPU with many qubits if the user decides to trade circuit depth for entangled qubits, or vice versa, depending on the type of algorithm the users is exploring.


Several proprietary software packages are available for integrating our systems into existing IT infrastructures. This has been successfully tested with systems delivered to VTT and LRZ. For end users, interfaces to standard programming interfaces, such as Cirq and Qiskit, are provided for direct execution of algorithms.


Leadership in quantum technologies has emerged as a major competition. By leveraging European technology, we support research centres and HPCs to maintain national sovereignty, ensuring access to parts, services, and upgrades even in uncertain times.


IQM is dedicated to providing computing power with a minimum carbon footprint. IQM is participating in the Quantum Energy Initiative (QEI), an international endeavor of 380 participants from over 56 countries which aims at a path towards energy-efficient, sustainable quantum technologies, and to bring out an energetic quantum advantage. Simulation of molecules, optimization of aerodynamic flows, or training of machine learning models require a very high amount of electricity in classical HPC centres with costs in the order of millions of Euros. In contrast, our systems consume less energy than a cozy Finnish sauna.

IQM Radiance™ ensures that you have access to the latest quantum technology with industry-leading performance.

IQM is building Finland’s first quantum computer with VTT

Our commitment to quality and excellence is exemplified by our successful partnership with institutions such as the VTT Technical Research Centre of Finland, where we built a remarkable 20-qubit quantum computer, achieving groundbreaking results. And we are already in the process of upgrading it into a 54-qubit system in the second quarter of 2024.

Frequently Asked Questions

What quantum algorithms are you exploring at the moment?

We actively investigate various quantum algorithms including optimization, simulation and quantum machine learning. Our experts create hardware-efficient algorithms including error-mitigation techniques which allows us to get the best performance out of our NISQ hardware.

For example, we have already significantly improved the performance compared to existing state-of-the-art routing algorithms for QAOA (Quantum Approximate Optimization Algorithm) circuit. See our paper for more details. More benchmark metrics will follow as we continue running experiments on IQM systems.

How do I integrate a quantum computer in an existing supercomputing environment?

Together with our HPC customers, we have tested different deployment architectures to maximize the performance of the hybrid classical-quantum systems. We developed a concept of a specialized system-wide resource manager to focus specifically on the quantum workloads and their complexities. As the algorithms require the input of a classical computation to happen within the lifetime of the qubits, an on-premises integration can reduce network latency and facilitate larger scale computations in the NISQ (Noisy Intermediate-Scale Quantum) era. For more details, see our Whitepaper.

What are the latest performance benchmarks of IQM hardware?

With our latest benchmarks measured on the 20-qubit quantum computer, we have demonstrated a median two-qubit (CZ) gate fidelity of 99.51% across 30 qubit pairs, with maximum fidelity over a single pair reaching as high as 99.8%.

Among the system-level benchmarks IQM obtained:

  • Quantum Volume (QV) of 25=32
  • Circuit Layer Operations Per Second (CLOPS) of 2600.
  • 20-qubit GHZ state with fidelity greater than 0.5.
  • Q-score of 11
