Due to the shift of Eurocrypt 2020 to an entirely online event, we decided to reschedule Quiques as affiliated event of Eurocrypt 2021 in Zagreb.

On March 11, 2020, as a consequence of the COVID-19 crisis, the IACR board decided to postpone Eurocrypt 2020 to a later date. As an affiliated event, also Quiques will be postponed.


Recently, the development of fault-tolerant quantum computers has accelerated, driven by heavy public and private investment. Due to this development, preparing the theory of cryptography for the arrival of quantum computers has become an important frontier of theoretical computer science. Mathematical tools for provable security in post-quantum and quantum cryptography have become a valuable resource. In addition, the exchange of ideas between the fields of cryptography and quantum information science is not as vivid as would be desirable due to the two fields traditionally being virtually without intersection.

This workshop strives to bring researchers from cryptography and quantum information science together to facilitate such an exchange of ideas, in particular with respect to quantum proof techniques that might be or already proved to be useful in cryptography. Topics will range from basic notions like quantum distinguishability measures and purification, to cutting-edge proof techniques overcoming the so-called “recording barrier” like superposition oracles and quantum rewinding.
