For our BASIQ project, we issued a call for tenders to find a partner for battery cell simulation at continuum level using quantum computers. With their proposal for algorithm and software development for solving partial differential equations in the field of lithium-ion batteries, the bidding consortium of the consulting company D-fine and the quantum computer manufacturer Planqc convinced us.
Partial differential equations can be used to simulate the interaction of the various components in an electrochemical cell – especially the electrodes and the electrolyte. Currently, the numerical solution of partial differential equations (PDEs) is carried out using conventional computers. However, this simulation approach reaches its limits with high-resolution, heterogeneous structures such as porous electrodes.
Significant acceleration
Quantum computers can lead to a significant acceleration of simulations even with a moderate number of qubits. An advantage can be achieved with just over 100 qubits – which makes implementation on our quantum computers possible.
In the QCI BASIQ (Battery Material Simulation with Quantum Computers) project, we aim to support the quantum computing industry in the development of innovative materials and products through research and development work. It is generally assumed that quantum simulations for materials research will be the first application of quantum computers with a practical quantum advantage. This is why the project specifically involves industrial partners. In addition to D-fine and Planqc, the start-ups HQS and Kipu Quantum have already been commissioned to simulate battery materials at the atomistic level, taking into account the noise of the quantum computer and using hybrid methods respectively.
We are very pleased about the exciting proposals and the special constellation of hardware and software expertise that will enrich QCI BASIQ, DLR QCI and thus the entire quantum computing ecosystem.
