Photocatalysis for water splitting
Problem
Toyota Motor Europe is collaborating with QAL on photocatalysis for water splitting, a crucial process for sustainable hydrogen production. Accurately simulating these reactions is complex and requires innovative computational methods.
Solution
The project uses an advanced quantum algorithm, the state-averaged orbital optimisation variational quantum eigensolver (SA-OOVQE), to simulate the energy interactions in photocatalysis. This algorithm enables accurate and efficient modelling of complex processes, providing deep insights into the interactions during photocatalysis.
Benefit
The use of SA-OOVQE in photocatalysis offers significant advantages. It improves the accuracy of simulations and provides deeper insights into reaction mechanisms, accelerating the research and development process. Simulations were conducted on a quantum simulator, and with further collaboration and hardware development, we expect to simulate increasingly larger systems.
