Scalability for your
future growing needs

IQM Radiance™ is designed from the ground up to be a modular system with uncompromising architecture. It comes with 54-qubits, with an opportunity to upgrade it to 150-qubits later.

IQM Radiance™ upgradable from 54 to 150-qubits

IQM Radiance™ will be delivered as a 54-qubit system with 144 qubits in total from which 90 qubits are used as coupler qubits for reaching high fidelity. Estimated availability end of 2024.

The modular architecture allows the customer to upgrade the system into a 150-qubit system with 416 qubits in total from which 266 qubits are used as coupler qubits. Estimated availability in 2025.

Why IQM Radiance™?

Assessing the hardware performance of quantum computers relies on several characteristics, which have to be well balanced in order to allow maximum usefulness for applications and algorithms. Superconducting technology performs well across all dimensions:

Number of qubits

With 54 high fidelity data qubits significant advances are foreseen in the field of executing quantum algorithms from optimization, simulation, and quantum machine learning for several application domains, like life sciences, chemistry, or industrials. In the version with 150 qubits end users will be able to discover new science or advantages for specific applications for which quantum utility can be realized, as this is far beyond the number of qubits that can be simulated on classical hardware.


High quality qubits with fidelities will allow to execute a significant number of quantum circuit steps on fully entangled qubits and are thus the key ingredient for the usefulness of our superconducting qubits.

Execution time

Even though the lifetime of superconducting qubits is not very high, the gates are extremely fast, which allows to execute thousands of gates during the lifetime of our qubits. The Circuit Layer Operations per Second (CLOPS) are much higher than in other qubit technologies, which removes a 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 maximal parallelization and consequently improved algorithm performance. Thus, maximum entanglement can be reached, and sub-patches of qubits can be defined with high flexibility. This allows 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. We provide further benefits for our end customers.

Integration to IT Infrastructure

Several proprietary software packages are available for integrating our systems into existing IT infrastructures. Of course, interfaces to standard programming interfaces, such as CIRQ and QISKIT, are provided for direct execution of algorithms. However, also integration packages into HPC centres are available, and have been tested for delivered systems (VTT, LRZ).

Made in Europe

With technology made in Europe we support the pursuit of research centres and HPCs for national sovereignty, and guarantee the availability of parts, services, and upgrades in potentially uncertain times.

Energy efficiency

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 possibly bring out an energetic quantum advantage.  Simulation of molecules, optimization of aerodynamic flows, or training of data models require 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 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 outstanding results. Our plan is to pilot the delivery of a 54-qubit system to VTT 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
