Team names are unique. The only way to guarantee your favourite name in the QML Challenge web portal is to create an account and grab it early. If your team has multiple members, check if one of your teammates has already created an account.

We recommend a maximum team size of 3 people. Teams of 4+ may also be acceptable, but the CERN internship prize has a maximum of three positions available.

No. Individuals can take part in the hackathon challenges independently. There is no distinction on the scoreboard between teams of one or teams with multiple members. Attendees can also choose to follow our livestream content without taking on the hackathon challenges (though we encourage you to do so!).

Recruit friends, work colleagues, classmates, or put the call out in existing communities such as the PennyLane discussion forum, the Xanadu Slack, the Unitary Fund Discord, or the QOSF Slack.

Our hackathon challenges will be based on PennyLane and Amazon Braket.

We will not be sharing specific example questions before the event. To best prepare, the ideal source of example material is the PennyLane QML website.

Multiple hackathon questions will be available, with different levels of difficulty. It is up to you how much time you would like to put in; simply choose a question to start with, and go from there! There is no requirement to answer every question.
