QBC: The Quantum Blockchain Cloud — debunking quantum myths and fables

Speaker: Roland van Rijswijk-Deij


In this talk I will focus on trying to discombobulate some of the common hypes and misunderstandings about the words quantum and cryptography in one sentence. This includes questions such as:

  • Can everybody decrypt my TLS if quantum is a thing?
  • Oh my god, quantum will be a thing next week, they're already selling 2000 qubit machines!
  • Quantum cryptography will solve all my problems
  • Post-quantum cryptography will solve all my problems

With a wink and a smile, the goal of this talk is to inform the audience about the real issues quantum computing may raise for Internet security and what they should and should not focus their energies on in dealing with this problem.


Roland is principal scientist at NLnet Labs, a not-for-profit foundation dedicated to research and development of core Internet protocols.

Next to his work at NLnet Labs, Roland is an assistant professor of computer network security at the University of Twente. His research interests include DNS(SEC), BGP and network security and stability. Roland obtained an M.Sc. in computer science from the University of Twente in 2001 and a cum laude PhD in computer science from the same university in 2017.

In his spare time, Roland very much enjoys finding new places to go scuba diving.
