Quantum duel: Do quantum computers exist?

Join the discussion between two world–leading scientists:

Matthias Christandl (University of Copenhagen):
Quantum bits are real! Yes, they are!

Gil Kalai (Reichman University and Hebrew University of Jerusalem):
Quantum Computers Won't Work.

The Learned Society of the Czech Republic is hosting a discussion on whether we will ever have practically relevant quantum computers. Matthias Christandl from the University of Copenhagen argues that qubits — units of information that are “both 0 and 1 at the same time” — have already been created, and that this will lead to the development of useful quantum computers. Gil Kalai from the Reichman University and the Hebrew University of Jerusalem does not dispute the creation of qubits, but he argues that, because of their inherent properties, we will never have practically relevant quantum computers.

Quantum computing is a computational model based on the principles of quantum physics. For certain computational tasks, ideal quantum computers are expected to outperform classical digital computers by many orders of magnitude, potentially rendering most current cryptosystems obsolete. While quantum computing presents an exciting vision for future technology, there is ongoing debate about its feasibility. Indeed, when or even whether scalable quantum computation is possible remains one of the most important scientific questions of our time.

Registration for the discussion is free.
