Instructions for QCrypt 2020 participants

The Zoom Webinar

The scientific presentations take place as a Zoom Webinar. Use the link in the invitation email (sent on Saturday, 8 Aug 2020) to access the webinar. You are then prompted to fill in your name and email address.

NB: It is required that you represent yourself by the full name that you use for your professional work (

During presentations, participants can use the Q&A functionality to pose questions to the speaker. For contributed-talk sessions with multiple speakers, make sure you address the question to a particular speaker. The session chair will then read out (some of) these questions to the speaker. Alternatively, there is the possibility to raise your hand; the session chair may then temporarily unmute you so that you can ask your question.

There is also a chat feature for private and public chatting. Updating your local zoom client to the latest version is generally advised.

The YouTube Channel

The Zoom Webinar is streamed live to YouTube, and recordings of all talks are available on the QCrypt Conference YouTube channel: . You can already find the pre-recorded videos of the contributed talks on the channel.

The Slack Workspace

The QCrypt Slack workspace enables interaction that is not restricted to the time of the day when the conference is actively running. For instance, participants that were not able to be present at the live presentation and Q&A can this way still ask questions about a presentation. Or, use the Slack private chat to agree on a time and place to meet in the Meet-&-Greet Room. Use the link from the invitation email (sent on Saturday, 8 Aug 2020) to subscribe to the QCrypt Slack channel.

The Meet-&-Greet Room

The breaks between the scientific presentations, as well as the two poster sessions, take place in the QCrypt 2020 Meet-&-Greet Room. This room is designed to enable, and hopefully stimulate, interaction between the participants. Beyond that, it offers the possibility for (more) private discussions with the speakers, and participants can visit the Sponsor Lounges and check out the pin boards there, and talk to the corresponding company- and institute-representatives.

The Meet-&-Greet Room (powered by is purely browser based. Up-to-date versions of Firefox, Chrome and Safari are supported; other browsers may not work (well).

Tutorial talks, Invited talks

The tutorial and invited talks are given live on the zoom webinar, and simultaneously streamed to YouTube. Webinar participants can ask questions via the zoom Q&A functionality. The speaker will answer the most important questions after the talk on zoom. After each session, the speaker is moving over to the Meet & Greet Room and will be available there to answer more individual questions (as it is usually the case at real-life conferences). The tutorial and invited talks are recorded and will be made available on the YouTube channel for offline watching.

Contributed talks

The list of accepted papers is here. After making a 20-25 minute video of their talks available before the conference, the live “online” part of presenting contributed articles is divided into thematic sessions on the zoom webinar. In each session, 3 to 4 contributed articles will be presented by means of a 5 minute talk each, followed by a panel discussion involving the speakers of the session and moderated by some members of the program committee. After each session, the speakers are moving over to the Meet & Greet Room and will be available there to answer more individual questions.

Poster sessions

The list of accepted posters with PDFs is now available on this website. The two poster sessions take place in the Meet & Greet Room. More details will be provided later.


The breaks between the talks can be spent in the Meet & Greet Room. Very much as with a physical conference, there you can meet and chat with your colleagues, corner the speaker from the previous session for (more) questions, visit the sponsor booths, and make new acquaintances. This is also the venue where the poster sessions take place.
