Goal of the Conference

QCRYPT is a conference for students and researchers who work on quantum cryptography, broadly defined. We invite research contributions on the possibilities and limitations of quantum methods for secure communication and computation. (Research on classical post-quantum cryptography is considered to be within scope if it makes innovative use of quantum information concepts.) QCRYPT features both experimental and theoretical talks.

Contributed Talks and Posters

QCrypt solicits submissions of extended abstracts describing recent research results in quantum cryptography. These will be reviewed by the program committee, which will select a small number of contributed talks, and a larger number of poster presentations. The selection will be based on scientific merit of the submissions, keeping in mind the desire to create an attractive and balanced program. A small number of submissions may be upgraded to invited talks at the discretion of the PC chair and of the steering committee.

In line with the goal of showcasing the best results each year from all subfields, the conference has no published proceedings. Yet, contributed talks are highly competitive. QCrypt welcomes the submission of any interesting and important result, while allowing researchers from a wide range of disciplines to pursue publication in any venue appropriate to their field.

Online conference

The conference will take place virtually during the week of August 23-27, 2021. The format and schdule will be similar to last year’s edition. The conference will feature invited speakers, contributed talks, poster sessions, tutorials, and industry exhibitions.

Submission Instructions

All submissions should be in PDF (Portable Document Format). An extended abstract for a talk submission should be 2-3 pages, in A4 or letter size, using reasonable margins and at least 11pt font. (The 3-page limit does not include references.) An extended abstract for a talk should give a non-technical, clear and insightful description of the results and main ideas, their impact, and their importance to quantum cryptography.

For a “poster only” submission, a one-page non-technical description is sufficient as an extended abstract.

The extended abstract may refer to technical details which are presented elsewhere. In particular, authors may include citations to a full version of the paper that is either published, available on or provided as an attachment (links to full versions on personal webpages are not accepted). This is strongly recommended for theory submissions to help the peer-review process. The extended abstract should not be a compressed version of the full-length paper.

The submission server is now available at:

Student Paper Prize

Since 2011, QCrypt features a prize for the best student submission. A submission is eligible for the student prize if and only if the main author(s) is/are a student(s) at the time of the submission, will present the work at QCrypt, and further a significant portion of the work must have been done by said student(s), including contributions to the key ideas. More details can be found in the Charter.
