Yfke Dulek is a Ph.D. student at the Centrum voor Wiskunde en Informatica and the Intitute for Logic, Language and Computation (University of Amsterdam), under the supervision of Christian Schaffner. There, she is also part of the research center QuSoft, where she works on quantum cryptography under computational assumptions, and in particular, quantum computing on encrypted data. She holds a B.Sc. in Artificial Intelligence from Utrecht University (2013) and a M.Sc. in Logic from the University of Amsterdam (2016).

Christian Schaffner received a diploma in mathematics from ETH Zurich (Switzerland) in 2003 and a Ph.D. in computer science from Aarhus University (Denmark) in 2007 under the supervision of Louis Salvail and Ivan Damgård. He is currently an Assistant Professor of Theoretical Computer Science at the Insitute for Logic, Language and Computation (ILLC) at the University of Amsterdam. He is also a senior researcher at QuSoft, the Dutch research center for quantum software. Christian's research interests include quantum cryptography, cryptographic protocols, and (quantum) information theory.

Florian Speelman performed his Ph.D. research at the Centrum voor Wiskunde en Informatica in Amsterdam, under the supervision of Harry Buhrman, receiving his degree in 2016. He also holds a B.Sc. in Physics and a M.Sc. in Computational Science from the University of Amsterdam. Florian's research interests include quantum cryptography, computational complexity theory, and communication complexity. He is currently a postdoctoral researcher at QMATH, the Centre for the Mathematics of Quantum Theory, at the University of Copenhagen.
