Physics Journals learning from Open Science
- American Physical Society has started an open access journal, Physical Review X (X doesn’t stand for eXtreme).
- The open-access journal, New Journal of Physics has learned from the open science Quantiki’s video abstract format for the arXiv [Previously: my video abstract], and have announced video abstracts for their journal.
It is good to see some of the biggest names in physics journals embrace ideas pioneered by the open sciences community.
I hope they push further! Any comments of future directions you would like them to take?

Lazy States: Sufficient and Necessary Condition for Zero Quantum Entropy Rates under any Coupling to the Environment
Phys. Rev. Lett. 106, 050403 (2011) [arXiv version]
César A. Rodríguez-Rosario, Gen Kimura, Hideki Imai, and Alán Aspuru-Guzik
We find the necessary and sufficient conditions for the entropy rate of the system to be zero under any system-environment Hamiltonian interaction. We call the class of system-environment states that satisfy this condition lazy states. They are a generalization of classically correlated states defined by quantum discord, but based on projective measurements of any rank. The concept of lazy states permits the construction of a protocol for detecting global quantum correlations using only local dynamical information. We show how quantum correlations to the environment provide bounds to the entropy rate, and how to estimate dissipation rates for general non-Markovian open quantum systems.
