I sometimes get messages from Codeforces members asking about the next installment of the Q# Coding Contest series. I don't have any news to share on that topic, but here is a quantum computing Hackathon that might be of interest for people who enjoyed Q# Coding Contests.
Quantum Coalition Hack is a quantum computing Hackathon hosted jointly by Yale Undergraduate Quantum Computing and Stanford Quantum Computing Association. Only undergraduate and graduate students worldwide are eligible to participate in the Hackathon part of the event, but everyone is welcome to attend the pre-Hackathon bootcamp on April 5-9 featuring tutorials and networking sessions. During the Hackathon itself, held on April 10-11, sponsor companies will offer programming challenges that can be solved using their technologies.
