We are delighted to announce that Devashish Tupkary, a graduate student in Professor Norbert Lütkenhaus’s research group at the University of Waterloo, has received the CryptoWorks21 Best Paper Award!

Devashish played a leading role in developing security proof framework for variable-length quantum key distribution (QKD) protocols. This work addresses critical limitations of traditional fixed-length approaches and paves the way for practical applications such as ground-to-satellite QKD, marking a major advancement in secure quantum communication.

Congratulations, Devashish, on this well-deserved recognition!
