Finnish company, Quanscient is developing a revolutionary simulation technology powered by cloud and quantum computing, enabling next-generation multiphysics simulations.

As the first of its kind product, Quanscient Allsolve, is the fastest multiphysics simulation software available. It offers fully digital R&D processes with its unique combination of native multiphysics algorithms, advanced cloud computing, and the prospect of future quantum integration. 

In addition, Quanscient has won the global Fujitsu $100,000 Quantum Simulator Challenge. This global competition invited members of the quantum industry and academia to test Fujitsu’s 39 qubit quantum simulator on unique problems and applications, aiming to accelerate research on advanced quantum technologies.

In the Fujitsu challenge, Quanscient’s winning project concentrated on quantum algorithms for fluid dynamics. The team conducted research on the performance of complex fluid simulations with the application of quantum techniques. Quanscient is focused on developing quantum algorithms with potential applications in vehicle, ship, and aircraft manufacturing, as well as biomedicine.

“This achievement not only underscores our expertise in quantum computing but also reinforces our role in addressing challenges in complex simulations,” says Quanscient’s Chief Scientist, Dr. Valtteri Lahtinen.

“Quanscient’s winning project demonstrated the remarkable potential of quantum algorithms in addressing societal challenges. Quanscient’s pioneering work in applying quantum techniques to the field of fluid dynamics holds a multitude of prospective applications,” says Hideto Okada, Head of Technology Strategy Unit of Fujitsu.


Development of quantum algorithms

Along with cloud-native multiphysics simulation, Quanscient has rapidly made significant advancements in quantum algorithm development. The company’s quantum team, a world leader in the quantum lattice Boltzmann method (QLBM) and specializing in computational fluid dynamics (CFD), is the first team globally to run a multiphysics simulation with real quantum hardware. Currently, Quanscient provides custom quantum algorithm development and licensing options for pilot customers.

In 2022, the company began researching Quantum lattice Boltzmann methods for quantum computing, achieving 1D simulations on a real quantum computer. The team later progressed to 2D simulations and optimized algorithms for larger-scale simulations. By 2023, they developed the Navier-Stokes solver and an imaginary time quantum linear solver, also researching lattice gas automata.

The company’s next goal is to advance 3D simulations by running a 3D quantum lattice Boltzmann simulation on a real quantum device. Quanscient intends to execute extensive quantum lattice Boltzmann simulations through collaborations with top quantum computer manufacturers, providing insight into the capacities of current devices.

With quantum simulations, Quanscient addresses a rapidly increasing demand for solutions for complex R&D. New technologies that can significantly benefit from quantum simulations are emerging, such as fusion energy and quantum hardware. Additionally, design complexity is increasing in many fields, including aerospace, automotive, and electronics.

“Our long-term quantum computing vision involves transitioning much of global computational fluid dynamics to quantum computing for its efficiency and lower CO2 emissions. We aim to expand our quantum algorithms to cover different physics types, which could enable currently unfeasible simulations, such as real-time digital twins of complete fusion power plants and airplanes. We aim to integrate our pioneering quantum algorithms into our simulation products in the next couple of years” Lahtinen explains.
