Hi Group,
As your lab dropbox admin, I enabled a new thing in Dropbox called "Dropbox
Paper", which is geared to nurture collaboration. It is Beta, so don´t
blame me if the thing is not smooth :)
We can learn more about it here: https://www.dropbox.com/paper (I am just
learning about it myself).
happy new year,
Adrian

Hi Everybody,
Happy new year! David Sutter and Philipp Kammerlander (ETH Zurich) are visiting us this week (Tuesday to Friday). Please let me know if you want to schedule a meeting. David is giving a talk tomorrow. Please find details below. I will announce Philipp’s talk (happening on Thursday) in a separate email.
Best,

Title: Relative entropy, recovery maps, and approximate quantum Markov chains
Place: 6C-442
Time: 1:30 (Jan 5)
Abstract: The Shannon and von Neumann entropies quantify the uncertainty in a system. They are operationally motivated by natural information processing tasks such as compression, channel coding or randomness extraction. A mathematical consequence of the postulates of quantum physics are several entropy inequalities such as the strong subadditivity of quantum entropy and the monotonicity of quantum relative entropy under physical processes. A series of recent works showed that these inequalities can be strengthened in the context of recoverability, i.e., by considering the question of how well a physical process can be reversed. This also provides an operational definition of approximate quantum Markov chains. In this talk, I will give an overview about the recent works on recoverability, present some new results, and discuss open problems. Based on joint work with Omar Fawzi, Aram Harrow, Marius Junge, Renato Renner, Marco Tomamichel, Mark M. Wilde, and Andreas Winter (arXiv:1504.07251, arXiv:1507.00303, and arXiv:1509.07127).
