Journal Club:

The journal club is a regular meeting to discuss current topics of interest (listed in the table below).
Regular participants are: Wilhelm Appelt , Markus Dutschke, Andreas Oestlin, Andreas Held
Past participants: Jaromir Panas, Kathrin Garb, Leonard Wossnig, Johannes Thiele
Further participants are welcome but should register in advance per mail in order to get precise information about the next meeting.


In general we meet Mondays at 13:00 at the coffee room of theo3 - this appointment is handeled on a flexible basis.

The one-way quantum computer - a non-network model of quantum computation

A one-way quantum computer works by only performing a sequence of one-qubit measurements on a particular entangled multi-qubit state, the cluster state. No non-local operations are required in the process of computation. Any quantum logic network can be simulated on the one-way quantum computer. On the other hand, the network model of quantum computation cannot explain all ways of processing quantum information possible with the one-way quantum computer. In this paper, two examples of the non-network character of the one-way quantum computer are given. First, circuits in the Clifford group can be performed in a single time step. Second, the realisation of a particular circuit --the bit-reversal gate-- on the one-way quantum computer has no network interpretation. (Submitted to J. Mod. Opt, Gdansk ESF QIT conference issue.)
