Abstract a state on a tripartite quantum system a⊗b⊗c a ⊗ b ⊗ c forms a markov chain if it can be reconstructed from its marginal on a⊗b a ⊗ b by a quantum operation from b to b⊗c b ⊗ c we show that the quantum conditional mutual information i(a : c|b) of an arbitrary state is an upper bound on its distance to the. Despite enormous theoretical and experimental progress in quantum cryptography, the security of most current implementations of quantum key distribution is still not rigorously established one significant problem is that the security of the final key strongly depends on the number, m, of signals exchanged.

Summary in  we prove two new quantum versions of the de finetti theorem, both showing that under tests formed by local measurements in each of the subsystems one can get a much improved error dependence on the dimension of the subsystems we also obtain similar results for non-signalling probability. Ph d thesis my thesis, quantum coarse-graining: an information-theoretic approach to thermodynamics, was elaborated under the supervision of renato renner in the quantum information theory group at eth zürich, and was defended in may 2016 thesis doi: 103929/ethz-a-010695790 arxiv: 160703104. Renato renner was born on december 11, 1974, in lucerne (switzerland) he studied physics, first at epf lausanne and later at eth zurich (switzerland), where he graduated in theoretical physics in 2000 he then moved to the computer science department of eth to work on a thesis in the area of. Thomas jennewein completed his phd thesis in 2002 at the university of vienna, focusing on quantum communication and teleportation experiments with entangled photon pairs he did a postdoc at icfo in the group of antonio acín in 2010-2011 and spent one year at eth zürich in the group of renato renner.

I would like to express my gratitude to my supervisors renato renner and ataç imamo˘glu almost two years ago i asked them for permission to change the topic of my phd thesis en- tirely to work on self-consistent tomography even though the study of self-consistent tomography has absolutely nothing to do with the. Irreversible information processing cannot be carried out without some inevitable thermodynamical work cost this fundamental restriction, known as landauer's principle, is increasingly relevant today, as the energy dissipation of computing devices impedes the development of their performance here we.

Abstract: we propose various new techniques in quantum information theory, including a de finetti style representation theorem for finite symmetric quantum states as an application, we give a proof for the security of quantum key distribution which applies to arbitrary protocols.
