Joris Kattemölle

Postdoc in quantum computing at the University of Konstanz, in the group of Guido Burkard.

Previously, I was a PhD candidate in theoretical physics at QuSoft and the University of Amsterdam, in the group of Jasper van Wezel.

My main research interest is the interface of many-body physics and quantum computation.

So what do you do?

For a recent layman's introduction to quantum simulation, quantum computation, and the work in my thesis, see here here (English) or here (Dutch).

For an even broader introduction to quantum computation, see the pop-sci articles below. They were originally published in Dutch on www.quantumuniverse.nl. Machine translations, which are quite good, are available.

Deel I: Makkelijk of Moeilijk?	Part I: Easy or Hard?
Deel II: Encryptie, bits en qubits	Part II: Encryption, bits and qubits
Deel III: Echte qubits	Part III: Real qubits

Likewise, I've written an article on The Firewall Paradox as a part of a series on black holes.
