The Theory of Quantum Computation, Communication and Cryptography (TQC) is a leading annual international conference for students and researchers working in the theoretical aspects of quantum information science. The scientific objective is to bring together the theoretical quantum information science community to present and discuss the latest advances in the field.

The 16th Conference on the Theory of Quantum Computation, Communication, and Cryptography (TQC 2021) will be held from July 5 to 8, 2021.

COVID-19 note: We are closely monitoring the development of the COVID-19 pandemic. If it is not viable to hold TQC 2021 as a physical conference at the University of Latvia in Riga, we will run it virtually on the same dates, and talks will be scheduled during Latvian business hours (GMT+2). We will decide in March 2021 at the latest. If TQC 2021 can go ahead physically, accepted authors may still present remotely.
