In normal physics of three (or higher dimensions or even on the line) there are two types of particles: bosons and fermions which are distinguished by giving a +1 or a -1 phase when two identical particles are exchanged.  However, in two dimensions different physics can happen:  when two identical particles are exchanged the effect can be any phase or even a matrix valued action on the state.

Just figured out how to do some pretty neat Bloch sphere's in Mathematica 6, using Sphere[], Graphics3D and ParametricPlot3D. They're interactive too.

The following code defines "bloch" which is a Graphics3D object that can be later used again, it's a bit more complicated than strickly necessary since I've added ket labels to the axes and other tweaks to make it look nice.

Since the Bekenstein-Hawking black hole entropy made its appearance in the seventies, the idea that the ultimate number of degrees of freedom in a region depends on the area of its boundary began to gain currency. The idea sounds surprising. Entropy measures the number of degrees of freedom (“the stuff”). Normally we expect its amount to grow with volume, as with the amount of stuff we can squeeze into a bag or a box.  The research in string theory and loop quantum gravity allowed to derive the “area laws” for black hole entropy  from the first principles, with only a small amount of additional assumptions. At the same time the black hole thermodynamics was developed.

2 new Postdoc posts are now available in the QISS group. The posts are to work in the area of quantum information theory: More specifically, from the advertising material:

I just caught up with one of my 2007 Honours students, James Freckleton who did an Honours project with me on Quantum Games. What is that you ask? There is a lot written about quantum games. People seem to have made much hullabaloo that the quantized games give different paybacks than the classical games...but of course...the quantum game is a completely different game and why should it not give different results? James an

We are submitting a paper on quantum transport using qudits and continuous variables. Attached is the Matlab Code and time dependant pulses referred to in the paper. By unpacking this archive and executing the matlab code one can see that the time dependant Hamiltonian generates $\hat{U}^\prime_a$ with 99% fidelity.
