The VQCC team at
Qcrypt 2024, in Vigo.

27/09/2024

From September 2 to 6, 2024, VQCC team attended the International Conference on Quantum Cryptography (Qcrypt 2024), which was held in the city of Vigo (Spain), with more than 300 attendees and supported by about 20 sponsors.

QCrypt is the most important conference in quantum communications. It is a conference for students and researchers working on all aspects of quantum cryptography, this includes theoretical and experimental research on the possibilities and limitations of secure communication and computation with quantum mechanical devices or in the presence of quantum mechanical devices (the conference includes but is not limited to research on quantum key distribution). It is the goal of the conference to represent the previous year’s best results on quantum cryptography and to support the building of a research community in quantum cryptography.

In 2024, the program included about 50 talks and 200 posters. In addition, a public lecture was offered to the general public, and a visit to the VQCC laboratories was organized. The congress program also offered a welcome reception and an excursion to the Cíes Islands to enable attendees to expand contacts and improve their networking.
