I study quantum matter in all its forms. I'm especially interested in entanglement, fractionalization (e.g. fractional quantum Hall effect and spin liquids), holographic duality, quantum information and computation, and non-equilibrium quantum dynamics.

comment Anybody have example of two-qubit non-Pauli and non-Clifford quantum gate?
It seems from your comment that you're now asking something much more general and complicated than before. The classes $C_n$ described in your reference are an infinite series of groups built from the Pauli group. Only $C_1$ and $C_2$ were mentioned in your original question, are these all you're interested in? Or do you also care about $C_n$ for $n>2$?

comment How can we define BF theory on a general 4-manifold?
Ok, I think I understand more what you're getting at. I'll edit my answer above.

comment Why is the $\langle v_{x}^{2} \rangle=\frac{1}{3} \langle v^2 \rangle$?
It's not true. The averages of two quantities can be equal without the quantities being equal. In your example above, clearly the x velocity and y velocity are two different physical quantities. It just happens that their squares have the same average value when you look at many particles.

Use dollar signs $ around your code
