QHack2021: Hackathon Recap and project development experience

On the 17th of February, the Xanadu team hosted its second quantum machine learning hackathon, QHack2021. Unlike the first hackathon which was held at Xanadu’s HQ in Toronto, this year, the event took place virtually, from February 17 till 26, giving the opportunity to experts and enthusiasts in quantum computing and quantum machine learning to participate from all around the world.


Before the event

One week before the hackathon kicked off, I managed to create a team. I used both the Xanadu Slack and the Unitary Fund Discord servers to reach out to other participants, within a few hours several participants responded, and the next day our team was formed, the “Entangled_Nets” team.

The QML Challenges

On the 17th, both the QML Challenges and QHack streaming sessions kicked off, with exciting talks and presentations from experts in the fields of quantum computing and quantum machine learning. There were two sessions a day with about 4 talks each, this lasted for 3 days with a total of 35 hours of live-streamed video with over 13,500 views. The recordings were made available on the QHack Twitch channel for later review.

The Open Hackathon

Although we had finished the QML challenges, we had 3 days till the Open Hackathon starts, which was a good pause to take a breath and plan for the final project, as we prepare before, we tried to divide the tasks that each one of us is responsible for, and on the 22nd the Open Hackathon kicked off with an introductory presentation to the AWS services.

QML is an extremely exciting field and the community is constantly expanding. Many people from different backgrounds are involved, and you can always find someone who will help and provide you with the necessary resources.


I would like to thank my teammates, Edo and Andrei(Voicu Tomut), for sharing their knowledge, coming up with unique solutions, and being open to new ideas. I couldn't have come this far without their help.
