March 05, 2025 -- At the launch of Europe’s first 50-qubit superconducting quantum computer, developed by VTT Technical Research Centre of Finland and IQM Quantum Computers, Quanscient demonstrated a groundbreaking achievement: the world’s first multi-time-step CFD simulation with Quantum Lattice-Boltzmann Method (QLBM) executed on a superconducting quantum computer.

As part of its collaboration with VTT, Quanscient Quantum Labs showcased the potential of quantum computing in engineering by running a QLBM simulation, marking the first CFD simulation of its kind on superconducting quantum hardware. This groundbreaking achievement opens up new possibilities for tackling CFD problems with quantum technology.

Traditional CFD simulations demand extensive computational resources and time, often limiting the speed of design iterations. With the successful execution of a 2D QLBM simulation on the VTT Q50 quantum computer, Quanscient Quantum Labs demonstrated how quantum computing can drastically accelerate these processes, offering a promising alternative for industries dealing with fluid dynamics challenges.

During the event, Dr. Valtteri Lahtinen, Chief Scientist and Co-founder at Quanscient, presented a simulation of an advection-diffusion equation using 12 qubits, highlighting the potential of quantum computers to address complex CFD applications. Through careful optimization of quantum circuits for the VTT Q50 gateset, Quanscient Quantum Labs demonstrated how quantum computing can enhance the accuracy and scalability of such simulations, bringing us closer to practical use in engineering.

This achievement brings quantum-enhanced CFD simulations one step closer to real-world applications in sectors like aerospace, automotive, and energy, where faster simulation times and improved design processes can significantly accelerate innovation.

Quanscient’s work at the VTT Q50 launch event clearly demonstrates its commitment to making the impossible possible with quantum computing. By proving that quantum simulations can handle practical CFD problems, Quanscient is driving the future of high-fidelity engineering simulations.
