Quantum Climate Challenge: Team EcoQult wins the Deloitte’s Quantum Climate Challenge

Team EcoQult wins the Deloitte’s Quantum Climate Challenge 

  • Belgian start-up prevails 
  • Contribute to the fight against climate change 
  • Pitch event live on the Hanover Fair stage 

Munich, 05. May 2023 — Leverage Quantum Computing for a better future:  That is the idea behind Deloitte’s yearly Quantum Climate Challenge. This  year the focus was on quantum simulation of chemical reactions. Team  EcoQult convinced the jury and won first prize. The team consists of three  employees from the Belgian start-up qBee, which deals with quantum  computing for chemical applications. 

“I would like to congratulate all participants for their submissions and ideas  and the EcoQult team for winning the first Deloitte Quantum Climate  Challenge. Their approach shows in a very direct way what possibilities  quantum computing already offers and what relevance this technology field  will have in the future,” says Renata Jovanovic, Partner & Sector Lead  Energy, Deloitte’s Global Quantum Computing Ambassador & Sponsor of the  Quantum Climate Challenge. 

Team EcoQult calculated the dissociation energy of multiple ion-gas systems  using multiple classical and quantum algorithms. Potential energy curves  were calculated with respect to distance and angular orientation. Results  were compared with respect to resource requirements, run-time and  accuracy of the solutions. For a larger system, a hybrid classical-quantum  algorithm was proposed and implemented. In this hybrid algorithm, the  energy of a six ions and six gas molecule system was first calculated using a 

computationally efficient classical method. Local corrections were then  performed by the VQE that showed the best accuracy for the simplified one  ion – one gas molecule system.  

The second place was won by Team JetiX – Their solution was focused on  improving the VQE algorithm to extend its capabilities. They used a de parameterization ansatz in combination with an initial point setter to  potentially speed up the optimization loop within VQE. A reduction in circuit  complexity and number of iterations until convergence without decreasing  the accuracy of the solution was demonstrated. For scale-up, density-matrix  embedding was proposed and tested for a smaller system. 

Team QuantuX, who won third place, followed a software-engineering  approach by developing a VQE pipline that allows the hyperparameters of  the VQE algorithm – such as choice of ansatz, basis set, qubit mapping and  optimizer – to be set using a dictionary fed into one function instead of  constructing the VQE step by step. They envision an automatic  hyperparameter setting for given chemical systems and have shown initial  step. 

Behind them on fourth and fifth place are Team Entangled Cats and Marc  Maussner. 

Quantum computing for materials research 

Deloitte’s 2023 Quantum Climate Challenge aims to explore how quantum  computing can help improve materials used in the direct capture of carbon  dioxide from the air. Over 120 participants from five continents took part in  the challenge, formed teams and developed 15 promising ideas. To do this,  the teams used a total of 130 hours of computing time on a quantum  computer, sometimes with 27 qubits, to immerse themselves deeply in the  simulation of chemical reactions. The main focus of the teams’ assessment  was how metal-organic frameworks can be used in direct air capture by  calculating the potential energy surface area of atmospheric gas molecules  near their preferred binding sites.
