• Quantum baker map from Marcos Saraceno and Leonardo Ermann. Marcos writes very nice and has deep intuition on quantum chaos, so I make a point on reading his papers. Plus, I made friends with Leo in Benasque which is another reason to read this.


• Unifyind decoherence and Heisenberg principle. This appears to go in line with Bub and Clifton's relation between information constrains and quantum mechanics. It is a little mathematical though.


• Finally, an Introduction to entanglement measures!!!


• This paper by Schack, Caves and others, is a very nice paper indeed. It shows very interesting relations between quantum and classical chaos, pointing to the direction of characterizing the former. However, I am disappointed at the way the authors jump around the studies on the Loschmidt echo, since 2001 up to the present. Their newest reference on decay of fidelity is in the 90s. I am sure Carl has seen my talks at least, so he knows very well the subject. Are the authors pissed at the Loschmidt echo community? They were working on the problem but never quite got to the point of identifying Lyapunov exponents in their quantum decays. This is not enough reason to "not-cite" a huge bunch of papers that are obviously related.


• Yet, another paper on entanglement and quantum phase transitions (static).


• A huge, long, and obsessively detailed review on quantum simulations using cold atoms. Very nice. What's with the formatting though?


• This is a very nice paper. A little technical at some points, but the ideas and results are beautiful.


• A useful paper


• Could this have some numerical testing? I think so, but I failed to have good numerics in a reasonable time for J. Emerson with an older algorithm (it is still running though...)


• Nice, could NP-complete problems be not so NP then?
