QEst Hack invites Nordic and Baltic teams to test quantum algorithms on real business problems

[Sophie64]

Metrosert, Estonia's Applied Research Centre, is inviting people from the Nordic and Baltic countries to apply for QEst Hack 2026, according to The Quantum Insider. The quantum hackathon runs from 11 to 13 November in Tallinn, and applications close on 11 October. Participation is free and the working language is English. IBM, IQM and the Université de Sherbrooke are co-organisers, with support from Estonia's Ministry of Economic Affairs and Communications

The format is practical. Five companies will present real business problems along with their own data, and teams of individuals, students and quantum experts from Estonia, Finland and Canada will test whether quantum algorithms can solve them better than existing methods. Possible problem areas include logistics, energy grid balancing, production planning, financial portfolios, material properties and drug discovery. That puts the emphasis on real use cases rather than toy problems

Kalev Kaarna, business development manager at Metrosert, said Estonia "must start building the necessary knowledge, experience and partnerships now" if it is not to fall behind neighbouring countries. The first QEst Hack in 2025 was won by energy company Enefit. Its head of AI systems, Kaarel Oja, said: "The hackathon prize enabled us to move from theoretical interest to practical experimentation." He added that it reduced the risk of trying something new

Estonia has a strong reputation for digital government and tech startups, so it is no surprise to see it trying to build quantum skills early. Small countries cannot fund national quantum computers on the scale of the UK or Germany, but they can build expertise and partnerships. Hackathons are a cheap and effective way to do that. It is a similar idea to the Moth Hack we discussed recently, but aimed at business problems rather than education

Do quantum hackathons produce anything useful, or are they mainly networking events? And would a UK equivalent with real business problems attract good teams?
